+// COMPUTED PROPERTY
+//
+
+/**
+ A computed property transforms an objects function into a property.
+
+ By default the function backing the computed property will only be called
+ once and the result will be cached. You can specify various properties
+ that your computed property is dependent on. This will force the cached
+ result to be recomputed if the dependencies are modified.
+
+ In the following example we declare a computed property (by calling
+ `.property()` on the fullName function) and setup the properties
+ dependencies (depending on firstName and lastName). The fullName function
+ will be called once (regardless of how many times it is accessed) as long
+ as it's dependencies have not been changed. Once firstName or lastName are updated
+ any future calls (or anything bound) to fullName will incorporate the new
+ values.
+
+ ```javascript
+ Person = Ember.Object.extend({
+ // these will be supplied by `create`
+ firstName: null,
+ lastName: null,
+
+ fullName: function() {
+ var firstName = this.get('firstName');
+ var lastName = this.get('lastName');
+
+ return firstName + ' ' + lastName;
+ }.property('firstName', 'lastName')
+ });
+
+ var tom = Person.create({
+ firstName: "Tom",
+ lastName: "Dale"
+ });
+
+ tom.get('fullName') // "Tom Dale"
+ ```
+
+ You can also define what Ember should do when setting a computed property.
+ If you try to set a computed property, it will be invoked with the key and
+ value you want to set it to. You can also accept the previous value as the
+ third parameter.
+
+ ```javascript
+
+ Person = Ember.Object.extend({
+ // these will be supplied by `create`
+ firstName: null,
+ lastName: null,
+
+ fullName: function(key, value, oldValue) {
+ // getter
+ if (arguments.length === 1) {
+ var firstName = this.get('firstName');
+ var lastName = this.get('lastName');
+
+ return firstName + ' ' + lastName;
+
+ // setter
+ } else {
+ var name = value.split(" ");
+
+ this.set('firstName', name[0]);
+ this.set('lastName', name[1]);
+
+ return value;
+ }
+ }.property('firstName', 'lastName')
+ });

+ data flow, `computed.oneWay` only provides an aliased `get`. The `set` will
+ not mutate the upstream property, rather causes the current property to
+ become the value set. This causes the downstream property to permentantly
+ diverge from the upstream property.
+
+ Example
+
+ ```javascript
+ User = Ember.Object.extend({
+ firstName: null,
+ lastName: null,
+ nickName: Ember.computed.oneWay('firstName')
+ });
+
+ user = User.create({
+ firstName: 'Teddy',
+ lastName: 'Zeenny'
+ });
+
+ user.get('nickName');
+ # 'Teddy'
+
+ user.set('nickName', 'TeddyBear');
+ # 'TeddyBear'
+
+ user.get('firstName');
+ # 'Teddy'
+ ```
+
+ @method computed.oneWay
+ @for Ember
+ @param {String} dependentKey
+ @return {Ember.ComputedProperty} computed property which creates a
+ one way computed property to the original value for property.
+*/

+ return Ember.computed(dependentKey, function() {
+ return get(this, dependentKey);
+ });
+};
+
+
+/**
+ A computed property that acts like a standard getter and setter,
+ but returns the value at the provided `defaultPath` if the
+ property itself has not been set to a value
+
+ Example
+
+ ```javascript
+ var Hamster = Ember.Object.extend({
+ wishList: Ember.computed.defaultTo('favoriteFood')

+
+ ```javascript

+ ```
+
+ Multiple operations scheduled with `Ember.run.next` will coalesce

+ scheduled by `Ember.run.later` that expire right around the same
+ time that `Ember.run.next` operations will fire.
+
+ Note that there are often alternatives to using `Ember.run.next`.
+ For instance, if you'd like to schedule an operation to happen
+ after all DOM element operations have completed within the current
+ run loop, you can make use of the `afterRender` run loop queue (added
+ by the `ember-views` package, along with the preceding `render` queue
+ where all the DOM element operations happen). Example:
+
+ ```javascript
+ App.MyCollectionView = Ember.CollectionView.extend({
+ didInsertElement: function() {
+ Ember.run.scheduleOnce('afterRender', this, 'processChildElements');
+ },
+ processChildElements: function() {
+ // ... do something with collectionView's child view
+ // elements after they've finished rendering, which
+ // can't be done within the CollectionView's
+ // `didInsertElement` hook because that gets run
+ // before the child elements have been added to the DOM.
+ }
+ });
+ ```
+
+ One benefit of the above approach compared to using `Ember.run.next` is
+ that you will be able to perform DOM/CSS operations before unprocessed
+ elements are rendered to the screen, which may prevent flickering or
+ other artifacts caused by delaying processing until after rendering.
+
+ The other major benefit to the above approach is that `Ember.run.next`
+ introduces an element of non-determinism, which can make things much
+ harder to test, due to its reliance on `setTimeout`; it's much harder
+ to guarantee the order of scheduled operations when they are scheduled
+ outside of the current run loop, i.e. with `Ember.run.next`.

+ An `Ember.Binding` connects the properties of two objects so that whenever
+ the value of one property changes, the other property will be changed also.
+
+ ## Automatic Creation of Bindings with `/^*Binding/`-named Properties
+
+ You do not usually create Binding objects directly but instead describe
+ bindings in your class or object definition using automatic binding
+ detection.
+
+ Properties ending in a `Binding` suffix will be converted to `Ember.Binding`
+ instances. The value of this property should be a string representing a path
+ to another object or a custom binding instanced created using Binding helpers
+ (see "One Way Bindings"):
+
+ ```
+ valueBinding: "MyApp.someController.title"
+ ```
+
+ This will create a binding from `MyApp.someController.title` to the `value`
+ property of your object instance automatically. Now the two values will be
+ kept in sync.
+
+ ## One Way Bindings
+
+ One especially useful binding customization you can use is the `oneWay()`
+ helper. This helper tells Ember that you are only interested in
+ receiving changes on the object you are binding from. For example, if you
+ are binding to a preference and you want to be notified if the preference
+ has changed, but your object will not be changing the preference itself, you
+ could do:
+
+ ```
+ bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles")
+ ```
+
+ This way if the value of `MyApp.preferencesController.bigTitles` changes the
+ `bigTitles` property of your object will change also. However, if you
+ change the value of your `bigTitles` property, it will not update the
+ `preferencesController`.
+
+ One way bindings are almost twice as fast to setup and twice as fast to
+ execute because the binding only has to worry about changes to one side.
+
+ You should consider using one way bindings anytime you have an object that
+ may be created frequently and you do not intend to change a property; only
+ to monitor it for changes (such as in the example above).
+
+ ## Adding Bindings Manually
+
+ All of the examples above show you how to configure a custom binding, but the
+ result of these customizations will be a binding template, not a fully active
+ Binding instance. The binding will actually become active only when you
+ instantiate the object the binding belongs to. It is useful however, to
+ understand what actually happens when the binding is activated.
+
+ For a binding to function it must have at least a `from` property and a `to`
+ property. The `from` property path points to the object/key that you want to
+ bind from while the `to` path points to the object/key you want to bind to.
+
+ When you define a custom binding, you are usually describing the property
+ you want to bind from (such as `MyApp.someController.value` in the examples
+ above). When your object is created, it will automatically assign the value
+ you want to bind `to` based on the name of your binding key. In the
+ examples above, during init, Ember objects will effectively call
+ something like this on your binding:
+
+ ```javascript
+ binding = Ember.Binding.from(this.valueBinding).to("value");
+ ```
+
+ This creates a new binding instance based on the template you provide, and
+ sets the to path to the `value` property of the new object. Now that the
+ binding is fully configured with a `from` and a `to`, it simply needs to be
+ connected to become active. This is done through the `connect()` method:
+
+ ```javascript
+ binding.connect(this);
+ ```
+
+ Note that when you connect a binding you pass the object you want it to be
+ connected to. This object will be used as the root for both the from and
+ to side of the binding when inspecting relative paths. This allows the
+ binding to be automatically inherited by subclassed objects as well.
+
+ Now that the binding is connected, it will observe both the from and to side
+ and relay changes.
+
+ If you ever needed to do so (you almost never will, but it is useful to
+ understand this anyway), you could manually create an active binding by
+ using the `Ember.bind()` helper method. (This is the same method used by
+ to setup your bindings on objects):
+
+ ```javascript
+ Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value");
+ ```
+
+ Both of these code fragments have the same effect as doing the most friendly
+ form of binding creation like so:
+
+ ```javascript
+ MyApp.anotherObject = Ember.Object.create({
+ valueBinding: "MyApp.someController.value",
+
+ // OTHER CODE FOR THIS OBJECT...
+ });
+ ```
+
+ Ember's built in binding creation method makes it easy to automatically
+ create bindings for you. You should always use the highest-level APIs
+ available, even if you understand how it works underneath.

+ `RSVP.denodeify` takes a "node-style" function and returns a function that
+ will return an `RSVP.Promise`. You can use `denodeify` in Node.js or the
+ browser when you'd prefer to use promises over using callbacks. For example,
+ `denodeify` transforms the following:
+
+ ```javascript
+ var fs = require('fs');
+
+ fs.readFile('myfile.txt', function(err, data){
+ if (err) return handleError(err);
+ handleData(data);
+ });
+ ```
+
+ into:
+
+ ```javascript
+ var fs = require('fs');
+
+ var readFile = RSVP.denodeify(fs.readFile);
+
+ readFile('myfile.txt').then(handleData, handleError);
+ ```
+
+ Using `denodeify` makes it easier to compose asynchronous operations instead
+ of using callbacks. For example, instead of:
+
+ ```javascript
+ var fs = require('fs');
+ var log = require('some-async-logger');
+
+ fs.readFile('myfile.txt', function(err, data){
+ if (err) return handleError(err);
+ fs.writeFile('myfile2.txt', data, function(err){
+ if (err) throw err;
+ log('success', function(err) {
+ if (err) throw err;
+ });
+ });
+ });
+ ```
+
+ You can chain the operations together using `then` from the returned promise:
+
+ ```javascript
+ var fs = require('fs');
+ var denodeify = RSVP.denodeify;
+ var readFile = denodeify(fs.readFile);
+ var writeFile = denodeify(fs.writeFile);
+ var log = denodeify(require('some-async-logger'));
+
+ readFile('myfile.txt').then(function(data){
+ return writeFile('myfile2.txt', data);
+ }).then(function(){
+ return log('SUCCESS');
+ }).then(function(){
+ // success handler
+ }, function(reason){
+ // rejection handler
+ });

+ /**
+ Promise objects represent the eventual result of an asynchronous operation. The
+ primary way of interacting with a promise is through its `then` method, which
+ registers callbacks to receive either a promise���s eventual value or the reason
+ why the promise cannot be fulfilled.
+
+ Terminology
+ -----------
+
+ - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
+ - `thenable` is an object or function that defines a `then` method.
+ - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
+ - `exception` is a value that is thrown using the throw statement.
+ - `reason` is a value that indicates why a promise was rejected.
+ - `settled` the final resting state of a promise, fulfilled or rejected.
+
+ A promise can be in one of three states: pending, fulfilled, or rejected.
+
+ Promises that are fulfilled have a fulfillment value and are in the fulfilled
+ state. Promises that are rejected have a rejection reason and are in the
+ rejected state. A fulfillment value is never a thenable. Similarly, a
+ rejection reason is never a thenable.
+
+ Promises can also be said to *resolve* a value. If this value is also a
+ promise, then the original promise's settled state will match the value's
+ settled state. So a promise that *resolves* a promise that rejects will
+ itself reject, and a promise that *resolves* a promise that fulfills will
+ itself fulfill.
+
+
+ Basic Usage:
+ ------------
+
+ ```js
+ var promise = new Promise(function(resolve, reject) {
+ // on success
+ resolve(value);
+
+ // on failure
+ reject(reason);
+ });
+
+ promise.then(function(value) {
+ // on fulfillment
+ }, function(reason) {
+ // on rejection
+ });
+ ```
+
+ Advanced Usage:
+ ---------------
+
+ Promises shine when abstracting away asynchronous interactions such as
+ `XMLHttpRequest`s.
+
+ ```js
+ function getJSON(url) {
+ return new Promise(function(resolve, reject){
+ var xhr = new XMLHttpRequest();
+
+ xhr.open('GET', url);
+ xhr.onreadystatechange = handler;
+ xhr.responseType = 'json';
+ xhr.setRequestHeader('Accept', 'application/json');
+ xhr.send();
+
+ function handler() {
+ if (this.readyState === this.DONE) {
+ if (this.status === 200) {
+ resolve(this.response);
+ } else {
+ reject(new Error("getJSON: `" + url + "` failed with status: [" + this.status + "]");
+ }
+ }
+ };
+ });
+ }
+
+ getJSON('/posts.json').then(function(json) {
+ // on fulfillment
+ }, function(reason) {
+ // on rejection
+ });
+ ```
+
+ Unlike callbacks, promises are great composable primitives.
+
+ ```js
+ Promise.all([
+ getJSON('/posts'),
+ getJSON('/comments')
+ ]).then(function(values){
+ values[0] // => postsJSON
+ values[1] // => commentsJSON
+
+ return values;
+ });
+ ```

+ The primary way of interacting with a promise is through its `then` method,
+ which registers callbacks to receive either a promise's eventual value or the

+
+ ```js
+ findUser().then(function(user){
+ // user is available
+ }, function(reason){
+ // user is unavailable, and you are given the reason why
+ });
+ ```
+
+ Chaining
+ --------
+
+ The return value of `then` is itself a promise. This second, "downstream"
+ promise is resolved with the return value of the first promise's fulfillment
+ or rejection handler, or rejected if the handler throws an exception.
+
+ ```js
+ findUser().then(function (user) {
+ return user.name;
+ }, function (reason) {
+ return "default name";
+ }).then(function (userName) {
+ // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
+ // will be `"default name"`
+ });
+
+ findUser().then(function (user) {
+ throw new Error("Found user, but still unhappy");
+ }, function (reason) {
+ throw new Error("`findUser` rejected and we're unhappy");
+ }).then(function (value) {
+ // never reached
+ }, function (reason) {
+ // if `findUser` fulfilled, `reason` will be "Found user, but still unhappy".
+ // If `findUser` rejected, `reason` will be "`findUser` rejected and we're unhappy".
+ });
+ ```
+ If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
+
+ ```js
+ findUser().then(function (user) {
+ throw new PedagogicalException("Upstream error");
+ }).then(function (value) {
+ // never reached
+ }).then(function (value) {
+ // never reached
+ }, function (reason) {
+ // The `PedgagocialException` is propagated all the way down to here
+ });
+ ```
+
+ Assimilation
+ ------------
+
+ Sometimes the value you want to propagate to a downstream promise can only be
+ retrieved asynchronously. This can be achieved by returning a promise in the
+ fulfillment or rejection handler. The downstream promise will then be pending
+ until the returned promise is settled. This is called *assimilation*.
+
+ ```js
+ findUser().then(function (user) {
+ return findCommentsByAuthor(user);
+ }).then(function (comments) {
+ // The user's comments are now available
+ });
+ ```
+
+ If the assimliated promise rejects, then the downstream promise will also reject.
+
+ ```js
+ findUser().then(function (user) {
+ return findCommentsByAuthor(user);
+ }).then(function (comments) {
+ // If `findCommentsByAuthor` fulfills, we'll have the value here
+ }, function (reason) {
+ // If `findCommentsByAuthor` rejects, we'll have the reason here
+ });
+ ```
+
+ Simple Example
+ --------------
+
+ Synchronous Example
+
+ ```javascript
+ var result;
+
+ try {
+ result = findResult();
+ // success
+ } catch(reason) {
+ // failure
+ }
+ ```

+ });
+
+ RSVP.Promise.race([promise1, promise2]).then(function(result){
+ // result === "promise 2" because it was resolved before promise1
+ // was resolved.
+ });
+ ```
+
+ `RSVP.Promise.race` is deterministic in that only the state of the first
+ settled promise matters. For example, even if other promises given to the
+ `promises` array argument are resolved, but the first settled promise has
+ become rejected before the other promises became fulfilled, the returned
+ promise will become rejected:
+
+ ```javascript
+ var promise1 = new RSVP.Promise(function(resolve, reject){
+ setTimeout(function(){
+ resolve("promise 1");
+ }, 200);
+ });
+
+ var promise2 = new RSVP.Promise(function(resolve, reject){
+ setTimeout(function(){
+ reject(new Error("promise 2"));
+ }, 100);
+ });
+
+ RSVP.Promise.race([promise1, promise2]).then(function(result){
+ // Code here never runs
+ }, function(reason){
+ // reason.message === "promise2" because promise 2 became rejected before
+ // promise 1 became fulfilled
+ });
+ ```
+
+ An example real-world use case is implementing timeouts:
+
+ ```javascript
+ RSVP.Promise.race([ajax('foo.json'), timeout(5000)])
+ ```
+
+ @method race
+ @param {Array} promises array of promises to observe
+ @param {String} label optional string for describing the promise returned.
+ Useful for tooling.

+/**
+ ## Overview
+
+ This mixin provides properties and property observing functionality, core
+ features of the Ember object model.
+
+ Properties and observers allow one object to observe changes to a
+ property on another object. This is one of the fundamental ways that
+ models, controllers and views communicate with each other in an Ember
+ application.
+
+ Any object that has this mixin applied can be used in observer
+ operations. That includes `Ember.Object` and most objects you will
+ interact with as you write your Ember application.
+
+ Note that you will not generally apply this mixin to classes yourself,
+ but you will use the features provided by this module frequently, so it
+ is important to understand how to use it.
+
+ ## Using `get()` and `set()`
+
+ Because of Ember's support for bindings and observers, you will always
+ access properties using the get method, and set properties using the
+ set method. This allows the observing objects to be notified and
+ computed properties to be handled properly.
+
+ More documentation about `get` and `set` are below.
+
+ ## Observing Property Changes
+
+ You typically observe property changes simply by adding the `observes`
+ call to the end of your method declarations in classes that you write.
+ For example:
+
+ ```javascript
+ Ember.Object.extend({
+ valueObserver: function() {
+ // Executes whenever the "value" property changes
+ }.observes('value')
+ });
+ ```
+
+ Although this is the most common way to add an observer, this capability
+ is actually built into the `Ember.Object` class on top of two methods
+ defined in this mixin: `addObserver` and `removeObserver`. You can use
+ these two methods to add and remove observers yourself if you need to
+ do so at runtime.
+
+ To add an observer for a property, call:
+
+ ```javascript
+ object.addObserver('propertyKey', targetObject, targetAction)
+ ```
+
+ This will call the `targetAction` method on the `targetObject` whenever
+ the value of the `propertyKey` changes.
+
+ Note that if `propertyKey` is a computed property, the observer will be
+ called when any of the property dependencies are changed, even if the
+ resulting value of the computed property is unchanged. This is necessary
+ because computed properties are not computed until `get` is called.
+
+ @class Observable
+ @namespace Ember
+*/
+Ember.Observable = Ember.Mixin.create({
+
+ /**
+ Retrieves the value of a property from the object.
+
+ This method is usually similar to using `object[keyName]` or `object.keyName`,
+ however it supports both computed properties and the unknownProperty
+ handler.
+
+ Because `get` unifies the syntax for accessing all these kinds
+ of properties, it can make many refactorings easier, such as replacing a
+ simple property with a computed property, or vice versa.
+
+ ### Computed Properties
+
+ Computed properties are methods defined with the `property` modifier
+ declared at the end, such as:
+
+ ```javascript
+ fullName: function() {
+ return this.get('firstName') + ' ' + this.get('lastName');
+ }.property('firstName', 'lastName')
+ ```
+
+ When you call `get` on a computed property, the function will be
+ called and the return value will be returned instead of the function
+ itself.
+
+ ### Unknown Properties
+
+ Likewise, if you try to call `get` on a property whose value is
+ `undefined`, the `unknownProperty()` method will be called on the object.
+ If this method returns any value other than `undefined`, it will be returned
+ instead. This allows you to implement "virtual" properties that are
+ not defined upfront.
+
+ @method get
+ @param {String} keyName The property to retrieve
+ @return {Object} The property value or undefined.
+ */
+ get: function(keyName) {
+ return get(this, keyName);
+ },
+
+ /**
+ To get multiple properties at once, call `getProperties`
+ with a list of strings or an array:
+
+ ```javascript
+ record.getProperties('firstName', 'lastName', 'zipCode'); // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
+ ```
+
+ is equivalent to:
+
+ ```javascript
+ record.getProperties(['firstName', 'lastName', 'zipCode']); // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
+ ```
+
+ @method getProperties
+ @param {String...|Array} list of keys to get
+ @return {Hash}
+ */
+ getProperties: function() {
+ return getProperties.apply(null, [this].concat(slice.call(arguments)));
+ },
+
+ /**
+ Sets the provided key or path to the value.
+
+ This method is generally very similar to calling `object[key] = value` or
+ `object.key = value`, except that it provides support for computed
+ properties, the `setUnknownProperty()` method and property observers.
+
+ ### Computed Properties
+
+ If you try to set a value on a key that has a computed property handler
+ defined (see the `get()` method for an example), then `set()` will call
+ that method, passing both the value and key instead of simply changing
+ the value itself. This is useful for those times when you need to
+ implement a property that is composed of one or more member
+ properties.
+
+ ### Unknown Properties
+
+ If you try to set a value on a key that is undefined in the target
+ object, then the `setUnknownProperty()` handler will be called instead. This
+ gives you an opportunity to implement complex "virtual" properties that
+ are not predefined on the object. If `setUnknownProperty()` returns
+ undefined, then `set()` will simply set the value on the object.
+
+ ### Property Observers
+
+ In addition to changing the property, `set()` will also register a property
+ change with the object. Unless you have placed this call inside of a
+ `beginPropertyChanges()` and `endPropertyChanges(),` any "local" observers
+ (i.e. observer methods declared on the same object), will be called
+ immediately. Any "remote" observers (i.e. observer methods declared on
+ another object) will be placed in a queue and called at a later time in a
+ coalesced manner.
+
+ ### Chaining
+
+ In addition to property changes, `set()` returns the value of the object
+ itself so you can do chaining like this:
+
+ ```javascript
+ record.set('firstName', 'Charles').set('lastName', 'Jolley');
+ ```
+
+ @method set
+ @param {String} keyName The property to set
+ @param {Object} value The value to set or `null`.
+ @return {Ember.Observable}
+ */

+ a single `beginPropertyChanges` and `endPropertyChanges` batch, so

+
+ Once you call this method, any time the key's value is set, your observer
+ will be notified. Note that the observers are triggered any time the
+ value is set, regardless of whether it has actually changed. Your
+ observer should be prepared to handle that.
+
+ You can also pass an optional context parameter to this method. The
+ context will be passed to your observer method whenever it is triggered.
+ Note that if you add the same target/method pair on a key multiple times
+ with different context parameters, your observer will only be called once
+ with the last context you passed.
+
+ ### Observer Methods
+
+ Observer methods you pass should generally have the following signature if
+ you do not pass a `context` parameter:
+
+ ```javascript
+ fooDidChange: function(sender, key, value, rev) { };
+ ```
+
+ The sender is the object that changed. The key is the property that
+ changes. The value property is currently reserved and unused. The rev
+ is the last property revision of the object when it changed, which you can
+ use to detect if the key value has really changed or not.
+
+ If you pass a `context` parameter, the context will be passed before the
+ revision like so:
+
+ ```javascript
+ fooDidChange: function(sender, key, value, context, rev) { };
+ ```
+
+ Usually you will not need the value, context or revision parameters at
+ the end. In this case, it is common to write observer methods that take
+ only a sender and key value as parameters or, if you aren't interested in
+ any of these values, to write an observer that has no parameters at all.

+ fooBarView.get('someNonConcatenatedProperty'); // ['foo']
+ fooBarView.get('classNames'); // ['ember-view', 'bar', 'foo']
+ ```
+
+ This behavior extends to object creation as well. Continuing the
+ above example:
+
+ ```javascript
+ var view = App.FooBarView.create({
+ someNonConcatenatedProperty: ['baz'],
+ classNames: ['baz']
+ })
+ view.get('someNonConcatenatedProperty'); // ['baz']
+ view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
+ ```
+ Adding a single property that is not an array will just add it in the array:
+
+ ```javascript
+ var view = App.FooBarView.create({
+ classNames: 'baz'
+ })
+ view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
+ ```
+
+ Using the `concatenatedProperties` property, we can tell to Ember that mix
+ the content of the properties.
+
+ In `Ember.View` the `classNameBindings` and `attributeBindings` properties
+ are also concatenated, in addition to `classNames`.
+
+ This feature is available for you to use throughout the Ember object model,
+ although typical app developers are likely to use it infrequently. Since
+ it changes expectations about behavior of properties, you should properly
+ document its usage in each individual concatenated property (to not
+ mislead your users to think they can override the property in a subclass).

+ Creates a new subclass.
+
+ ```javascript
+ App.Person = Ember.Object.extend({

+ alert(thing);
+ }
+ });
+ ```
+
+ This defines a new subclass of Ember.Object: `App.Person`. It contains one method: `say()`.
+
+ You can also create a subclass from any existing class by calling its `extend()` method. For example, you might want to create a subclass of Ember's built-in `Ember.View` class:
+
+ ```javascript
+ App.PersonView = Ember.View.extend({
+ tagName: 'li',
+ classNameBindings: ['isAdministrator']
+ });
+ ```
+
+ When defining a subclass, you can override methods but still access the implementation of your parent class by calling the special `_super()` method:
+
+ ```javascript
+ App.Person = Ember.Object.extend({
+ say: function(thing) {
+ var name = this.get('name');
+ alert(name + ' says: ' + thing);
+ }
+ });
+
+ App.Soldier = App.Person.extend({

+ this._super(thing + ", sir!");
+ },
+ march: function(numberOfHours) {
+ alert(this.get('name') + ' marches for ' + numberOfHours + ' hours.')
+ }
+ });
+
+ var yehuda = App.Soldier.create({
+ name: "Yehuda Katz"
+ });
+
+ yehuda.say("Yes"); // alerts "Yehuda Katz says: Yes, sir!"
+ ```
+
+ The `create()` on line #17 creates an *instance* of the `App.Soldier` class. The `extend()` on line #8 creates a *subclass* of `App.Person`. Any instance of the `App.Person` class will *not* have the `march()` method.
+
+ You can also pass `Ember.Mixin` classes to add additional properties to the subclass.
+
+ ```javascript
+ App.Person = Ember.Object.extend({
+ say: function(thing) {
+ alert(this.get('name') + ' says: ' + thing);

+ dance: function() {
+ alert(this.get('name') + ' dances: tap tap tap tap ');
+ }
+ });
+ ```
+
+ The `App.BroadwayStar` class contains three methods: `say()`, `sing()`, and `dance()`.

+/**
+ This mixin defines the common interface implemented by enumerable objects
+ in Ember. Most of these methods follow the standard Array iteration
+ API defined up to JavaScript 1.8 (excluding language-specific features that
+ cannot be emulated in older versions of JavaScript).
+
+ This mixin is applied automatically to the Array class on page load, so you
+ can use any of these methods on simple arrays. If Array already implements
+ one of these methods, the mixin will not override them.
+
+ ## Writing Your Own Enumerable
+
+ To make your own custom class enumerable, you need two items:
+
+ 1. You must have a length property. This property should change whenever
+ the number of items in your enumerable object changes. If you using this
+ with an `Ember.Object` subclass, you should be sure to change the length
+ property using `set().`
+
+ 2. You must implement `nextObject().` See documentation.
+
+ Once you have these two methods implement, apply the `Ember.Enumerable` mixin
+ to your class and you will be able to enumerate the contents of your object
+ like any other collection.
+
+ ## Using Ember Enumeration with Other Libraries
+
+ Many other libraries provide some kind of iterator or enumeration like
+ facility. This is often where the most common API conflicts occur.
+ Ember's API is designed to be as friendly as possible with other
+ libraries by implementing only methods that mostly correspond to the
+ JavaScript 1.8 API.

+ Implement this method to make your class enumerable.
+
+ This method will be call repeatedly during enumeration. The index value
+ will always begin with 0 and increment monotonically. You don't have to
+ rely on the index value to determine what object to return, but you should
+ always check the value and start from the beginning when you see the
+ requested index is 0.
+
+ The `previousObject` is the object that was returned from the last call
+ to `nextObject` for the current iteration. This is a useful way to
+ manage iteration if you are tracing a linked list, for example.
+
+ Finally the context parameter will always contain a hash you can use as
+ a "scratchpad" to maintain any other state you need in order to iterate
+ properly. The context object is reused and is not reset between
+ iterations so make sure you setup the context with a fresh state whenever
+ the index parameter is 0.
+
+ Generally iterators will continue to call `nextObject` until the index
+ reaches the your current length-1. If you run out of data before this
+ time for some reason, you should simply return undefined.
+
+ The default implementation of this method simply looks up the index.
+ This works great on any Array-like objects.

+/**
+ This module implements Observer-friendly Array-like behavior. This mixin is
+ picked up by the Array class as well as other controllers, etc. that want to
+ appear to be arrays.
+
+ Unlike `Ember.Enumerable,` this mixin defines methods specifically for
+ collections that provide index-ordered access to their contents. When you
+ are designing code that needs to accept any kind of Array-like object, you
+ should use these methods instead of Array primitives because these will
+ properly notify observers of changes to the array.
+
+ Although these methods are efficient, they do add a layer of indirection to
+ your application so it is a good idea to use them only when you need the
+ flexibility of using both true JavaScript arrays and "virtual" arrays such
+ as controllers and collections.
+
+ You can use the methods defined in this module to access and modify array
+ contents in a KVO-friendly way. You can also be notified whenever the
+ membership of an array changes by changing the syntax of the property to
+ `.observes('*myProperty.[]')`.
+
+ To support `Ember.Array` in your own class, you must override two
+ primitives to use it: `replace()` and `objectAt()`.
+
+ Note that the Ember.Array mixin also incorporates the `Ember.Enumerable`
+ mixin. All `Ember.Array`-like objects are also enumerable.

+/**
+ Creates a computed property which operates on dependent arrays and
+ is updated with "one at a time" semantics. When items are added or
+ removed from the dependent array(s) a reduce computed only operates
+ on the change instead of re-evaluating the entire array.
+
+ If there are more than one arguments the first arguments are
+ considered to be dependent property keys. The last argument is
+ required to be an options object. The options object can have the
+ following four properties:
+
+ `initialValue` - A value or function that will be used as the initial
+ value for the computed. If this property is a function the result of calling
+ the function will be used as the initial value. This property is required.
+
+ `initialize` - An optional initialize function. Typically this will be used
+ to set up state on the instanceMeta object.
+
+ `removedItem` - A function that is called each time an element is removed
+ from the array.
+
+ `addedItem` - A function that is called each time an element is added to
+ the array.
+
+
+ The `initialize` function has the following signature:
+
+ ```javascript
+ function (initialValue, changeMeta, instanceMeta)
+ ```
+
+ `initialValue` - The value of the `initialValue` property from the
+ options object.
+
+ `changeMeta` - An object which contains meta information about the
+ computed. It contains the following properties:
+
+ - `property` the computed property
+ - `propertyName` the name of the property on the object
+
+ `instanceMeta` - An object that can be used to store meta
+ information needed for calculating your computed. For example a
+ unique computed might use this to store the number of times a given
+ element is found in the dependent array.
+
+
+ The `removedItem` and `addedItem` functions both have the following signature:
+
+ ```javascript
+ function (accumulatedValue, item, changeMeta, instanceMeta)
+ ```
+
+ `accumulatedValue` - The value returned from the last time
+ `removedItem` or `addedItem` was called or `initialValue`.
+
+ `item` - the element added or removed from the array
+
+ `changeMeta` - An object which contains meta information about the
+ change. It contains the following properties:
+
+ - `property` the computed property
+ - `propertyName` the name of the property on the object
+ - `index` the index of the added or removed item
+ - `item` the added or removed item: this is exactly the same as
+ the second arg
+ - `arrayChanged` the array that triggered the change. Can be
+ useful when depending on multiple arrays.
+
+ For property changes triggered on an item property change (when
+ depKey is something like `someArray.@each.someProperty`),
+ `changeMeta` will also contain the following property:
+
+ - `previousValues` an object whose keys are the properties that changed on
+ the item, and whose values are the item's previous values.
+
+ `previousValues` is important Ember coalesces item property changes via
+ Ember.run.once. This means that by the time removedItem gets called, item has
+ the new values, but you may need the previous value (eg for sorting &
+ filtering).
+
+ `instanceMeta` - An object that can be used to store meta
+ information needed for calculating your computed. For example a
+ unique computed might use this to store the number of times a given
+ element is found in the dependent array.
+
+ The `removedItem` and `addedItem` functions should return the accumulated
+ value. It is acceptable to not return anything (ie return undefined)
+ to invalidate the computation. This is generally not a good idea for
+ arrayComputed but it's used in eg max and min.
+
+ Note that observers will be fired if either of these functions return a value
+ that differs from the accumulated value. When returning an object that
+ mutates in response to array changes, for example an array that maps
+ everything from some other array (see `Ember.computed.map`), it is usually
+ important that the *same* array be returned to avoid accidentally triggering observers.
+
+ Example
+
+ ```javascript
+ Ember.computed.max = function (dependentKey) {
+ return Ember.reduceComputed.call(null, dependentKey, {
+ initialValue: -Infinity,
+
+ addedItem: function (accumulatedValue, item, changeMeta, instanceMeta) {
+ return Math.max(accumulatedValue, item);
+ },
+
+ removedItem: function (accumulatedValue, item, changeMeta, instanceMeta) {
+ if (item < accumulatedValue) {
+ return accumulatedValue;
+ }
+ }
+ });
+ };
+ ```
+
+ Dependent keys may refer to `@this` to observe changes to the object itself,
+ which must be array-like, rather than a property of the object. This is
+ mostly useful for array proxies, to ensure objects are retrieved via
+ `objectAtContent`. This is how you could sort items by properties defined on an item controller.
+
+ Example
+
+ ```javascript
+ App.PeopleController = Ember.ArrayController.extend({
+ itemController: 'person',
+
+ sortedPeople: Ember.computed.sort('@this.@each.reversedName', function(personA, personB) {
+ // `reversedName` isn't defined on Person, but we have access to it via
+ // the item controller App.PersonController. If we'd used
+ // `content.@each.reversedName` above, we would be getting the objects
+ // directly and not have access to `reversedName`.
+ //
+ var reversedNameA = get(personA, 'reversedName'),
+ reversedNameB = get(personB, 'reversedName');
+
+ return Ember.compare(reversedNameA, reversedNameB);
+ })
+ });
+
+ App.PersonController = Ember.ObjectController.extend({
+ reversedName: function () {
+ return reverse(get(this, 'name'));
+ }.property('name')
+ })
+ ```
+
+ Dependent keys whose values are not arrays are treated as regular
+ dependencies: when they change, the computed property is completely
+ recalculated. It is sometimes useful to have dependent arrays with similar
+ semantics. Dependent keys which end in `.[]` do not use "one at a time"
+ semantics. When an item is added or removed from such a dependency, the
+ computed property is completely recomputed.
+
+ Example
+
+ ```javascript
+ Ember.Object.extend({
+ // When `string` is changed, `computed` is completely recomputed.
+ string: 'a string',
+
+ // When an item is added to `array`, `addedItem` is called.
+ array: [],
+
+ // When an item is added to `anotherArray`, `computed` is completely
+ // recomputed.
+ anotherArray: [],
+
+ computed: Ember.reduceComputed('string', 'array', 'anotherArray.[]', {
+ addedItem: addedItemCallback,
+ removedItem: removedItemCallback
+ })
+ });
+ ```

+ Computed properties allow you to treat a function like a property:
+
+ ```javascript

+ lastName: '',
+
+ fullName: function() {

+
+ Treating a function like a property is useful because they can work with
+ bindings, just like any other property.
+
+ Many computed properties have dependencies on other properties. For
+ example, in the above example, the `fullName` property depends on
+ `firstName` and `lastName` to determine its value. You can tell Ember
+ about these dependencies like this:
+
+ ```javascript
+ MyApp.President = Ember.Object.extend({
+ firstName: '',
+ lastName: '',
+
+ fullName: function() {

+
+ // Tell Ember.js that this computed property depends on firstName
+ // and lastName
+ }.property('firstName', 'lastName')
+ });
+ ```
+
+ Make sure you list these dependencies so Ember knows when to update
+ bindings that connect to a computed property. Changing a dependency
+ will not immediately trigger an update of the computed property, but
+ will instead clear the cache so that it is updated when the next `get`
+ is called on the property.

+/**
+ The `Ember.Freezable` mixin implements some basic methods for marking an
+ object as frozen. Once an object is frozen it should be read only. No changes
+ may be made the internal state of the object.
+
+ ## Enforcement
+
+ To fully support freezing in your subclass, you must include this mixin and
+ override any method that might alter any property on the object to instead
+ raise an exception. You can check the state of an object by checking the
+ `isFrozen` property.
+
+ Although future versions of JavaScript may support language-level freezing
+ object objects, that is not the case today. Even if an object is freezable,
+ it is still technically possible to modify the object, even though it could
+ break other parts of your application that do not expect a frozen object to
+ change. It is, therefore, very important that you always respect the
+ `isFrozen` property on all freezable objects.
+
+ ## Example Usage
+
+ The example below shows a simple object that implement the `Ember.Freezable`
+ protocol.
+
+ ```javascript
+ Contact = Ember.Object.extend(Ember.Freezable, {
+ firstName: null,
+ lastName: null,
+
+ // swaps the names
+ swapNames: function() {
+ if (this.get('isFrozen')) throw Ember.FROZEN_ERROR;
+ var tmp = this.get('firstName');
+ this.set('firstName', this.get('lastName'));
+ this.set('lastName', tmp);
+ return this;
+ }
+
+ });
+
+ c = Contact.create({ firstName: "John", lastName: "Doe" });
+ c.swapNames(); // returns c
+ c.freeze();
+ c.swapNames(); // EXCEPTION
+ ```
+
+ ## Copying
+
+ Usually the `Ember.Freezable` protocol is implemented in cooperation with the
+ `Ember.Copyable` protocol, which defines a `frozenCopy()` method that will
+ return a frozen object, if the object implements this method as well.
+
+ @class Freezable
+ @namespace Ember
+ @since Ember 0.9

+ For example, a MappedEnumerable cannot be directly modified but if its

+
+ ## Adding Objects
+
+ To add an object to an enumerable, use the `addObject()` method. This

+
+ ```javascript

+ ```
+
+ ## Implementing In Your Own Code
+
+ If you are implementing an object and want to support this API, just include

+
+ These functions will be invoked when a matching `{{action}}` is triggered
+ from within a template and the application's current route is this route.
+
+ Actions can also be invoked from other parts of your application
+ via `ActionHandler#send`.
+
+ The `actions` hash will inherit action handlers from
+ the `actions` hash defined on extended parent classes
+ or mixins rather than just replace the entire hash, e.g.:
+
+ ```js
+ App.CanDisplayBanner = Ember.Mixin.create({

+ // ...
+ }
+ }
+ });
+

+ // `WelcomeRoute`, when active, will be able to respond
+ // to both actions, since the actions hash is merged rather
+ // then replaced when extending mixins / parent classes.
+ this.send('displayBanner');
+ this.send('playMusic');
+ ```
+
+ Within a Controller, Route, View or Component's action handler,
+ the value of the `this` context is the Controller, Route, View or
+ Component object:
+
+ ```js
+ App.SongRoute = Ember.Route.extend({
+ actions: {
+ myAction: function() {
+ this.controllerFor("song");
+ this.transitionTo("other.route");
+ ...
+ }
+ }
+ });
+ ```
+
+ It is also possible to call `this._super()` from within an
+ action handler if it overrides a handler defined on a parent
+ class or mixin:
+
+ Take for example the following routes:
+
+ ```js
+ App.DebugRoute = Ember.Mixin.create({
+ actions: {
+ debugRouteInformation: function() {
+ console.debug("trololo");
+ }
+ }
+ });

+ this._super();
+
+ // show additional annoyance
+ window.alert(...);
+ }
+ }
+ });
+ ```
+
+ ## Bubbling
+
+ By default, an action will stop bubbling once a handler defined
+ on the `actions` hash handles it. To continue bubbling the action,
+ you must return `true` from the handler:
+
+ ```js
+ App.Router.map(function() {
+ this.resource("album", function() {
+ this.route("song");
+ });
+ });
+
+ App.AlbumRoute = Ember.Route.extend({

+/**
+ An unordered collection of objects.
+
+ A Set works a bit like an array except that its items are not ordered. You
+ can create a set to efficiently test for membership for an object. You can
+ also iterate through a set just like an array, even accessing objects by
+ index, however there is no guarantee as to their order.
+
+ All Sets are observable via the Enumerable Observer API - which works
+ on any enumerable object including both Sets and Arrays.
+
+ ## Creating a Set
+
+ You can create a set like you would most objects using
+ `new Ember.Set()`. Most new sets you create will be empty, but you can
+ also initialize the set with some content by passing an array or other
+ enumerable of objects to the constructor.
+
+ Finally, you can pass in an existing set and the set will be copied. You
+ can also create a copy of a set by calling `Ember.Set#copy()`.
+
+ ```javascript
+ // creates a new empty set
+ var foundNames = new Ember.Set();
+
+ // creates a set with four names in it.
+ var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P
+
+ // creates a copy of the names set.
+ var namesCopy = new Ember.Set(names);
+
+ // same as above.
+ var anotherNamesCopy = names.copy();
+ ```
+
+ ## Adding/Removing Objects
+
+ You generally add or remove objects from a set using `add()` or
+ `remove()`. You can add any type of object including primitives such as
+ numbers, strings, and booleans.
+
+ Unlike arrays, objects can only exist one time in a set. If you call `add()`
+ on a set with the same object multiple times, the object will only be added
+ once. Likewise, calling `remove()` with the same object multiple times will
+ remove the object the first time and have no effect on future calls until
+ you add the object to the set again.
+
+ NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do
+ so will be ignored.
+
+ In addition to add/remove you can also call `push()`/`pop()`. Push behaves
+ just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary
+ object, remove it and return it. This is a good way to use a set as a job
+ queue when you don't care which order the jobs are executed in.
+
+ ## Testing for an Object
+
+ To test for an object's presence in a set you simply call
+ `Ember.Set#contains()`.
+
+ ## Observing changes
+
+ When using `Ember.Set`, you can observe the `"[]"` property to be
+ alerted whenever the content changes. You can also add an enumerable
+ observer to the set to be notified of specific objects that are added and
+ removed from the set. See [Ember.Enumerable](/api/classes/Ember.Enumerable.html)
+ for more information on enumerables.
+
+ This is often unhelpful. If you are filtering sets of objects, for instance,
+ it is very inefficient to re-filter all of the items each time the set
+ changes. It would be better if you could just adjust the filtered set based
+ on what was changed on the original set. The same issue applies to merging
+ sets, as well.
+
+ ## Other Methods
+
+ `Ember.Set` primary implements other mixin APIs. For a complete reference
+ on the methods you will use with `Ember.Set`, please consult these mixins.
+ The most useful ones will be `Ember.Enumerable` and
+ `Ember.MutableEnumerable` which implement most of the common iterator
+ methods you are used to on Array.
+
+ Note that you can also use the `Ember.Copyable` and `Ember.Freezable`
+ APIs on `Ember.Set` as well. Once a set is frozen it can no longer be
+ modified. The benefit of this is that when you call `frozenCopy()` on it,
+ Ember will avoid making copies of the set. This allows you to write
+ code that can know with certainty when the underlying set data will or
+ will not be modified.

+/**
+ `Ember.ArrayController` provides a way for you to publish a collection of
+ objects so that you can easily bind to the collection from a Handlebars
+ `#each` helper, an `Ember.CollectionView`, or other controllers.
+
+ The advantage of using an `ArrayController` is that you only have to set up
+ your view bindings once; to change what's displayed, simply swap out the
+ `content` property on the controller.
+
+ For example, imagine you wanted to display a list of items fetched via an XHR
+ request. Create an `Ember.ArrayController` and set its `content` property:
+
+ ```javascript
+ MyApp.listController = Ember.ArrayController.create();
+
+ $.get('people.json', function(data) {
+ MyApp.listController.set('content', data);
+ });
+ ```
+
+ Then, create a view that binds to your new controller:
+
+ ```handlebars
+ {{#each MyApp.listController}}
+ {{firstName}} {{lastName}}
+ {{/each}}
+ ```
+
+ Although you are binding to the controller, the behavior of this controller
+ is to pass through any methods or properties to the underlying array. This
+ capability comes from `Ember.ArrayProxy`, which this class inherits from.
+
+ Sometimes you want to display computed properties within the body of an
+ `#each` helper that depend on the underlying items in `content`, but are not
+ present on those items. To do this, set `itemController` to the name of a
+ controller (probably an `ObjectController`) that will wrap each individual item.
+
+ For example:
+
+ ```handlebars
+ {{#each post in controller}}
+ <li>{{title}} ({{titleLength}} characters)</li>
+ {{/each}}
+ ```
+
+ ```javascript
+ App.PostsController = Ember.ArrayController.extend({
+ itemController: 'post'
+ });
+
+ App.PostController = Ember.ObjectController.extend({
+ // the `title` property will be proxied to the underlying post.
+
+ titleLength: function() {
+ return this.get('title').length;
+ }.property('title')
+ });
+ ```
+
+ In some cases it is helpful to return a different `itemController` depending
+ on the particular item. Subclasses can do this by overriding
+ `lookupItemController`.
+
+ For example:
+
+ ```javascript
+ App.MyArrayController = Ember.ArrayController.extend({
+ lookupItemController: function( object ) {
+ if (object.get('isSpecial')) {
+ return "special"; // use App.SpecialController
+ } else {
+ return "regular"; // use App.RegularController
+ }
+ }
+ });
+ ```
+
+ The itemController instances will have a `parentController` property set to
+ either the the `parentController` property of the `ArrayController`
+ or to the `ArrayController` instance itself.

+/**
+ `Ember.View` is the class in Ember responsible for encapsulating templates of
+ HTML content, combining templates with data to render as sections of a page's
+ DOM, and registering and responding to user-initiated events.
+
+ ## HTML Tag
+
+ The default HTML tag name used for a view's DOM representation is `div`. This
+ can be customized by setting the `tagName` property. The following view
+ class:
+
+ ```javascript
+ ParagraphView = Ember.View.extend({
+ tagName: 'em'
+ });
+ ```
+
+ Would result in instances with the following HTML:
+
+ ```html
+ <em id="ember1" class="ember-view"></em>
+ ```
+
+ ## HTML `class` Attribute
+
+ The HTML `class` attribute of a view's tag can be set by providing a
+ `classNames` property that is set to an array of strings:
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNames: ['my-class', 'my-other-class']
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view my-class my-other-class"></div>
+ ```
+
+ `class` attribute values can also be set by providing a `classNameBindings`
+ property set to an array of properties names for the view. The return value
+ of these properties will be added as part of the value for the view's `class`
+ attribute. These properties can be computed properties:
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNameBindings: ['propertyA', 'propertyB'],
+ propertyA: 'from-a',
+ propertyB: function() {
+ if (someLogic) { return 'from-b'; }
+ }.property()
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view from-a from-b"></div>
+ ```
+
+ If the value of a class name binding returns a boolean the property name
+ itself will be used as the class name if the property is true. The class name
+ will not be added if the value is `false` or `undefined`.
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNameBindings: ['hovered'],
+ hovered: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view hovered"></div>
+ ```
+
+ When using boolean class name bindings you can supply a string value other
+ than the property name for use as the `class` HTML attribute by appending the
+ preferred value after a ":" character when defining the binding:
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNameBindings: ['awesome:so-very-cool'],
+ awesome: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view so-very-cool"></div>
+ ```
+
+ Boolean value class name bindings whose property names are in a
+ camelCase-style format will be converted to a dasherized format:
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNameBindings: ['isUrgent'],
+ isUrgent: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view is-urgent"></div>
+ ```
+
+ Class name bindings can also refer to object values that are found by
+ traversing a path relative to the view itself:
+
+ ```javascript
+ MyView = Ember.View.extend({
+ classNameBindings: ['messages.empty']
+ messages: Ember.Object.create({
+ empty: true
+ })
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view empty"></div>
+ ```
+
+ If you want to add a class name for a property which evaluates to true and
+ and a different class name if it evaluates to false, you can pass a binding
+ like this:
+
+ ```javascript
+ // Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false
+ Ember.View.extend({
+ classNameBindings: ['isEnabled:enabled:disabled']
+ isEnabled: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view enabled"></div>
+ ```
+
+ When isEnabled is `false`, the resulting HTML reprensentation looks like
+ this:
+
+ ```html
+ <div id="ember1" class="ember-view disabled"></div>
+ ```
+
+ This syntax offers the convenience to add a class if a property is `false`:
+
+ ```javascript
+ // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false
+ Ember.View.extend({
+ classNameBindings: ['isEnabled::disabled']
+ isEnabled: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view"></div>
+ ```
+
+ When the `isEnabled` property on the view is set to `false`, it will result
+ in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view disabled"></div>
+ ```
+
+ Updates to the the value of a class name binding will result in automatic
+ update of the HTML `class` attribute in the view's rendered HTML
+ representation. If the value becomes `false` or `undefined` the class name
+ will be removed.
+
+ Both `classNames` and `classNameBindings` are concatenated properties. See
+ [Ember.Object](/api/classes/Ember.Object.html) documentation for more
+ information about concatenated properties.
+
+ ## HTML Attributes
+
+ The HTML attribute section of a view's tag can be set by providing an
+ `attributeBindings` property set to an array of property names on the view.
+ The return value of these properties will be used as the value of the view's
+ HTML associated attribute:
+
+ ```javascript
+ AnchorView = Ember.View.extend({
+ tagName: 'a',
+ attributeBindings: ['href'],
+ href: 'http://google.com'
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <a id="ember1" class="ember-view" href="http://google.com"></a>
+ ```
+
+ If the return value of an `attributeBindings` monitored property is a boolean
+ the property will follow HTML's pattern of repeating the attribute's name as
+ its value:
+
+ ```javascript
+ MyTextInput = Ember.View.extend({
+ tagName: 'input',
+ attributeBindings: ['disabled'],
+ disabled: true
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <input id="ember1" class="ember-view" disabled="disabled" />
+ ```
+
+ `attributeBindings` can refer to computed properties:
+
+ ```javascript
+ MyTextInput = Ember.View.extend({
+ tagName: 'input',
+ attributeBindings: ['disabled'],
+ disabled: function() {
+ if (someLogic) {
+ return true;
+ } else {
+ return false;
+ }
+ }.property()
+ });
+ ```
+
+ Updates to the the property of an attribute binding will result in automatic
+ update of the HTML attribute in the view's rendered HTML representation.
+
+ `attributeBindings` is a concatenated property. See [Ember.Object](/api/classes/Ember.Object.html)
+ documentation for more information about concatenated properties.
+
+ ## Templates
+
+ The HTML contents of a view's rendered representation are determined by its
+ template. Templates can be any function that accepts an optional context
+ parameter and returns a string of HTML that will be inserted within the
+ view's tag. Most typically in Ember this function will be a compiled
+ `Ember.Handlebars` template.
+
+ ```javascript
+ AView = Ember.View.extend({
+ template: Ember.Handlebars.compile('I am the template')
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view">I am the template</div>
+ ```
+
+ Within an Ember application is more common to define a Handlebars templates as
+ part of a page:
+
+ ```html
+ <script type='text/x-handlebars' data-template-name='some-template'>
+ Hello
+ </script>
+ ```
+
+ And associate it by name using a view's `templateName` property:
+
+ ```javascript
+ AView = Ember.View.extend({
+ templateName: 'some-template'
+ });
+ ```
+
+ If you have nested resources, your Handlebars template will look like this:
+
+ ```html
+ <script type='text/x-handlebars' data-template-name='posts/new'>
+ <h1>New Post</h1>
+ </script>
+ ```
+
+ And `templateName` property:
+
+ ```javascript
+ AView = Ember.View.extend({
+ templateName: 'posts/new'
+ });
+ ```
+
+ Using a value for `templateName` that does not have a Handlebars template
+ with a matching `data-template-name` attribute will throw an error.
+
+ For views classes that may have a template later defined (e.g. as the block
+ portion of a `{{view}}` Handlebars helper call in another template or in
+ a subclass), you can provide a `defaultTemplate` property set to compiled
+ template function. If a template is not later provided for the view instance
+ the `defaultTemplate` value will be used:
+
+ ```javascript
+ AView = Ember.View.extend({
+ defaultTemplate: Ember.Handlebars.compile('I was the default'),
+ template: null,
+ templateName: null
+ });
+ ```
+
+ Will result in instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view">I was the default</div>
+ ```
+
+ If a `template` or `templateName` is provided it will take precedence over
+ `defaultTemplate`:
+
+ ```javascript
+ AView = Ember.View.extend({
+ defaultTemplate: Ember.Handlebars.compile('I was the default')
+ });
+
+ aView = AView.create({
+ template: Ember.Handlebars.compile('I was the template, not default')
+ });
+ ```
+
+ Will result in the following HTML representation when rendered:
+
+ ```html
+ <div id="ember1" class="ember-view">I was the template, not default</div>
+ ```
+
+ ## View Context
+
+ The default context of the compiled template is the view's controller:
+
+ ```javascript
+ AView = Ember.View.extend({
+ template: Ember.Handlebars.compile('Hello {{excitedGreeting}}')
+ });
+
+ aController = Ember.Object.create({
+ firstName: 'Barry',
+ excitedGreeting: function() {
+ return this.get("content.firstName") + "!!!"
+ }.property()
+ });
+
+ aView = AView.create({
+ controller: aController,
+ });
+ ```
+
+ Will result in an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view">Hello Barry!!!</div>
+ ```
+
+ A context can also be explicitly supplied through the view's `context`
+ property. If the view has neither `context` nor `controller` properties, the
+ `parentView`'s context will be used.
+
+ ## Layouts
+
+ Views can have a secondary template that wraps their main template. Like
+ primary templates, layouts can be any function that accepts an optional
+ context parameter and returns a string of HTML that will be inserted inside
+ view's tag. Views whose HTML element is self closing (e.g. `<input />`)
+ cannot have a layout and this property will be ignored.
+
+ Most typically in Ember a layout will be a compiled `Ember.Handlebars`
+ template.
+
+ A view's layout can be set directly with the `layout` property or reference
+ an existing Handlebars template by name with the `layoutName` property.
+
+ A template used as a layout must contain a single use of the Handlebars
+ `{{yield}}` helper. The HTML contents of a view's rendered `template` will be
+ inserted at this location:
+
+ ```javascript
+ AViewWithLayout = Ember.View.extend({
+ layout: Ember.Handlebars.compile("<div class='my-decorative-class'>{{yield}}</div>")
+ template: Ember.Handlebars.compile("I got wrapped"),
+ });
+ ```
+
+ Will result in view instances with an HTML representation of:
+
+ ```html
+ <div id="ember1" class="ember-view">
+ <div class="my-decorative-class">
+ I got wrapped
+ </div>
+ </div>
+ ```
+
+ See [Ember.Handlebars.helpers.yield](/api/classes/Ember.Handlebars.helpers.html#method_yield)
+ for more information.
+
+ ## Responding to Browser Events
+
+ Views can respond to user-initiated events in one of three ways: method
+ implementation, through an event manager, and through `{{action}}` helper use
+ in their template or layout.
+
+ ### Method Implementation
+
+ Views can respond to user-initiated events by implementing a method that
+ matches the event name. A `jQuery.Event` object will be passed as the
+ argument to this method.
+
+ ```javascript
+ AView = Ember.View.extend({
+ click: function(event) {
+ // will be called when when an instance's
+ // rendered element is clicked
+ }
+ });
+ ```
+
+ ### Event Managers
+
+ Views can define an object as their `eventManager` property. This object can
+ then implement methods that match the desired event names. Matching events
+ that occur on the view's rendered HTML or the rendered HTML of any of its DOM
+ descendants will trigger this method. A `jQuery.Event` object will be passed
+ as the first argument to the method and an `Ember.View` object as the
+ second. The `Ember.View` will be the view whose rendered HTML was interacted
+ with. This may be the view with the `eventManager` property or one of its
+ descendent views.
+
+ ```javascript
+ AView = Ember.View.extend({
+ eventManager: Ember.Object.create({
+ doubleClick: function(event, view) {
+ // will be called when when an instance's
+ // rendered element or any rendering
+ // of this views's descendent
+ // elements is clicked
+ }
+ })
+ });
+ ```
+
+ An event defined for an event manager takes precedence over events of the
+ same name handled through methods on the view.
+
+ ```javascript
+ AView = Ember.View.extend({
+ mouseEnter: function(event) {
+ // will never trigger.
+ },
+ eventManager: Ember.Object.create({
+ mouseEnter: function(event, view) {
+ // takes precedence over AView#mouseEnter
+ }
+ })
+ });
+ ```
+
+ Similarly a view's event manager will take precedence for events of any views
+ rendered as a descendent. A method name that matches an event name will not
+ be called if the view instance was rendered inside the HTML representation of
+ a view that has an `eventManager` property defined that handles events of the
+ name. Events not handled by the event manager will still trigger method calls
+ on the descendent.
+
+ ```javascript
+ OuterView = Ember.View.extend({
+ template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"),
+ eventManager: Ember.Object.create({
+ mouseEnter: function(event, view) {
+ // view might be instance of either
+ // OuterView or InnerView depending on
+ // where on the page the user interaction occured
+ }
+ })
+ });
+
+ InnerView = Ember.View.extend({
+ click: function(event) {
+ // will be called if rendered inside
+ // an OuterView because OuterView's
+ // eventManager doesn't handle click events
+ },
+ mouseEnter: function(event) {
+ // will never be called if rendered inside
+ // an OuterView.
+ }
+ });
+ ```
+
+ ### Handlebars `{{action}}` Helper
+
+ See [Handlebars.helpers.action](/api/classes/Ember.Handlebars.helpers.html#method_action).
+
+ ### Event Names
+
+ All of the event handling approaches described above respond to the same set
+ of events. The names of the built-in events are listed below. (The hash of
+ built-in events exists in `Ember.EventDispatcher`.) Additional, custom events
+ can be registered by using `Ember.Application.customEvents`.
+
+ Touch events:
+
+ * `touchStart`
+ * `touchMove`
+ * `touchEnd`
+ * `touchCancel`
+
+ Keyboard events
+
+ * `keyDown`
+ * `keyUp`
+ * `keyPress`
+
+ Mouse events
+
+ * `mouseDown`
+ * `mouseUp`
+ * `contextMenu`
+ * `click`
+ * `doubleClick`
+ * `mouseMove`
+ * `focusIn`
+ * `focusOut`
+ * `mouseEnter`
+ * `mouseLeave`
+
+ Form events:
+
+ * `submit`
+ * `change`
+ * `focusIn`
+ * `focusOut`
+ * `input`
+
+ HTML5 drag and drop events:
+
+ * `dragStart`
+ * `drag`
+ * `dragEnter`
+ * `dragLeave`
+ * `drop`
+ * `dragEnd`
+
+ ## Handlebars `{{view}}` Helper
+
+ Other `Ember.View` instances can be included as part of a view's template by
+ using the `{{view}}` Handlebars helper. See [Ember.Handlebars.helpers.view](/api/classes/Ember.Handlebars.helpers.html#method_view)
+ for additional information.

+ A `ContainerView` is an `Ember.View` subclass that implements `Ember.MutableArray`
+ allowing programmatic management of its child views.
+
+ ## Setting Initial Child Views
+
+ The initial array of child views can be set in one of two ways. You can
+ provide a `childViews` property at creation time that contains instance of
+ `Ember.View`:
+
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ childViews: [Ember.View.create(), Ember.View.create()]
+ });
+ ```
+
+ You can also provide a list of property names whose values are instances of
+ `Ember.View`:
+
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ childViews: ['aView', 'bView', 'cView'],
+ aView: Ember.View.create(),
+ bView: Ember.View.create(),
+ cView: Ember.View.create()
+ });
+ ```
+
+ The two strategies can be combined:
+
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ childViews: ['aView', Ember.View.create()],
+ aView: Ember.View.create()
+ });
+ ```
+
+ Each child view's rendering will be inserted into the container's rendered
+ HTML in the same order as its position in the `childViews` property.
+
+ ## Adding and Removing Child Views
+
+ The container view implements `Ember.MutableArray` allowing programmatic management of its child views.
+
+ To remove a view, pass that view into a `removeObject` call on the container view.
+
+ Given an empty `<body>` the following code
+
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ classNames: ['the-container'],
+ childViews: ['aView', 'bView'],
+ aView: Ember.View.create({
+ template: Ember.Handlebars.compile("A")
+ }),
+ bView: Ember.View.create({
+ template: Ember.Handlebars.compile("B")
+ })
+ });
+
+ aContainer.appendTo('body');
+ ```
+
+ Results in the HTML
+
+ ```html
+ <div class="ember-view the-container">
+ <div class="ember-view">A</div>
+ <div class="ember-view">B</div>
+ </div>
+ ```
+
+ Removing a view
+
+ ```javascript
+ aContainer.toArray(); // [aContainer.aView, aContainer.bView]
+ aContainer.removeObject(aContainer.get('bView'));
+ aContainer.toArray(); // [aContainer.aView]
+ ```
+
+ Will result in the following HTML
+
+ ```html
+ <div class="ember-view the-container">
+ <div class="ember-view">A</div>
+ </div>
+ ```
+
+ Similarly, adding a child view is accomplished by adding `Ember.View` instances to the
+ container view.
+
+ Given an empty `<body>` the following code
+
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ classNames: ['the-container'],
+ childViews: ['aView', 'bView'],
+ aView: Ember.View.create({
+ template: Ember.Handlebars.compile("A")
+ }),
+ bView: Ember.View.create({
+ template: Ember.Handlebars.compile("B")
+ })
+ });
+
+ aContainer.appendTo('body');
+ ```
+
+ Results in the HTML
+
+ ```html
+ <div class="ember-view the-container">
+ <div class="ember-view">A</div>
+ <div class="ember-view">B</div>
+ </div>
+ ```
+
+ Adding a view
+
+ ```javascript
+ AnotherViewClass = Ember.View.extend({
+ template: Ember.Handlebars.compile("Another view")
+ });
+
+ aContainer.toArray(); // [aContainer.aView, aContainer.bView]
+ aContainer.pushObject(AnotherViewClass.create());
+ aContainer.toArray(); // [aContainer.aView, aContainer.bView, <AnotherViewClass instance>]
+ ```
+
+ Will result in the following HTML
+
+ ```html
+ <div class="ember-view the-container">
+ <div class="ember-view">A</div>
+ <div class="ember-view">B</div>
+ <div class="ember-view">Another view</div>
+ </div>
+ ```
+
+ ## Templates and Layout
+
+ A `template`, `templateName`, `defaultTemplate`, `layout`, `layoutName` or
+ `defaultLayout` property on a container view will not result in the template
+ or layout being rendered. The HTML contents of a `Ember.ContainerView`'s DOM
+ representation will only be the rendered HTML of its child views.

+
+/**
+ `Ember.CollectionView` is an `Ember.View` descendent responsible for managing
+ a collection (an array or array-like object) by maintaining a child view object
+ and associated DOM representation for each item in the array and ensuring
+ that child views and their associated rendered HTML are updated when items in
+ the array are added, removed, or replaced.
+
+ ## Setting content
+
+ The managed collection of objects is referenced as the `Ember.CollectionView`
+ instance's `content` property.
+
+ ```javascript
+ someItemsView = Ember.CollectionView.create({
+ content: ['A', 'B','C']
+ })
+ ```
+
+ The view for each item in the collection will have its `content` property set
+ to the item.
+
+ ## Specifying itemViewClass
+
+ By default the view class for each item in the managed collection will be an
+ instance of `Ember.View`. You can supply a different class by setting the
+ `CollectionView`'s `itemViewClass` property.
+
+ Given an empty `<body>` and the following code:
+
+ ```javascript
+ someItemsView = Ember.CollectionView.create({
+ classNames: ['a-collection'],
+ content: ['A','B','C'],
+ itemViewClass: Ember.View.extend({
+ template: Ember.Handlebars.compile("the letter: {{view.content}}")
+ })
+ });
+
+ someItemsView.appendTo('body');
+ ```
+
+ Will result in the following HTML structure
+
+ ```html
+ <div class="ember-view a-collection">
+ <div class="ember-view">the letter: A</div>
+ <div class="ember-view">the letter: B</div>
+ <div class="ember-view">the letter: C</div>
+ </div>
+ ```
+
+ ## Automatic matching of parent/child tagNames
+
+ Setting the `tagName` property of a `CollectionView` to any of
+ "ul", "ol", "table", "thead", "tbody", "tfoot", "tr", or "select" will result
+ in the item views receiving an appropriately matched `tagName` property.
+
+ Given an empty `<body>` and the following code:
+
+ ```javascript
+ anUndorderedListView = Ember.CollectionView.create({
+ tagName: 'ul',
+ content: ['A','B','C'],
+ itemViewClass: Ember.View.extend({
+ template: Ember.Handlebars.compile("the letter: {{view.content}}")
+ })
+ });
+
+ anUndorderedListView.appendTo('body');
+ ```
+
+ Will result in the following HTML structure
+
+ ```html
+ <ul class="ember-view a-collection">
+ <li class="ember-view">the letter: A</li>
+ <li class="ember-view">the letter: B</li>
+ <li class="ember-view">the letter: C</li>
+ </ul>
+ ```
+
+ Additional `tagName` pairs can be provided by adding to
+ `Ember.CollectionView.CONTAINER_MAP `
+
+ ```javascript
+ Ember.CollectionView.CONTAINER_MAP['article'] = 'section'
+ ```
+
+ ## Programmatic creation of child views
+
+ For cases where additional customization beyond the use of a single
+ `itemViewClass` or `tagName` matching is required CollectionView's
+ `createChildView` method can be overidden:
+
+ ```javascript
+ CustomCollectionView = Ember.CollectionView.extend({
+ createChildView: function(viewClass, attrs) {
+ if (attrs.content.kind == 'album') {
+ viewClass = App.AlbumView;
+ } else {
+ viewClass = App.SongView;
+ }
+ return this._super(viewClass, attrs);
+ }
+ });
+ ```
+
+ ## Empty View
+
+ You can provide an `Ember.View` subclass to the `Ember.CollectionView`
+ instance as its `emptyView` property. If the `content` property of a
+ `CollectionView` is set to `null` or an empty array, an instance of this view
+ will be the `CollectionView`s only child.
+
+ ```javascript
+ aListWithNothing = Ember.CollectionView.create({
+ classNames: ['nothing']
+ content: null,
+ emptyView: Ember.View.extend({
+ template: Ember.Handlebars.compile("The collection is empty")
+ })
+ });
+
+ aListWithNothing.appendTo('body');
+ ```
+
+ Will result in the following HTML structure
+
+ ```html
+ <div class="ember-view nothing">
+ <div class="ember-view">
+ The collection is empty
+ </div>
+ </div>
+ ```
+
+ ## Adding and Removing items
+
+ The `childViews` property of a `CollectionView` should not be directly
+ manipulated. Instead, add, remove, replace items from its `content` property.
+ This will trigger appropriate changes to its rendered HTML.

+/**
+ An `Ember.Component` is a view that is completely
+ isolated. Property access in its templates go
+ to the view object and actions are targeted at
+ the view object. There is no access to the
+ surrounding context or outer controller; all
+ contextual information must be passed in.
+
+ The easiest way to create an `Ember.Component` is via
+ a template. If you name a template
+ `components/my-foo`, you will be able to use
+ `{{my-foo}}` in other templates, which will make
+ an instance of the isolated component.
+
+ ```html
+ {{app-profile person=currentUser}}
+ ```
+
+ ```html
+ <!-- app-profile template -->
+ <h1>{{person.title}}</h1>
+ <img {{bind-attr src=person.avatar}}>
+ <p class='signature'>{{person.signature}}</p>
+ ```
+
+ You can use `yield` inside a template to
+ include the **contents** of any block attached to
+ the component. The block will be executed in the
+ context of the surrounding context or outer controller:
+
+ ```handlebars
+ {{#app-profile person=currentUser}}
+ <p>Admin mode</p>
+ {{! Executed in the controllers context. }}
+ {{/app-profile}}
+ ```
+
+ ```handlebars
+ <!-- app-profile template -->
+ <h1>{{person.title}}</h1>
+ {{! Executed in the components context. }}
+ {{yield}} {{! block contents }}
+ ```
+
+ If you want to customize the component, in order to
+ handle events or actions, you implement a subclass
+ of `Ember.Component` named after the name of the
+ component. Note that `Component` needs to be appended to the name of
+ your subclass like `AppProfileComponent`.
+
+ For example, you could implement the action
+ `hello` for the `app-profile` component:
+
+ ```javascript
+ App.AppProfileComponent = Ember.Component.extend({
+ actions: {
+ hello: function(name) {
+ console.log("Hello", name);
+ }
+ }
+ });
+ ```
+
+ And then use it in the component's template:
+
+ ```html
+ <!-- app-profile template -->
+
+ <h1>{{person.title}}</h1>
+ {{yield}} <!-- block contents -->
+
+ <button {{action 'hello' person.name}}>
+ Say Hello to {{person.name}}
+ </button>
+ ```
+
+ Components must have a `-` in their name to avoid
+ conflicts with built-in controls that wrap HTML
+ elements. This is consistent with the same
+ requirement in web components.

+/**
+ Register a bound handlebars helper. Bound helpers behave similarly to regular
+ handlebars helpers, with the added ability to re-render when the underlying data
+ changes.
+
+ ## Simple example
+
+ ```javascript
+ Ember.Handlebars.registerBoundHelper('capitalize', function(value) {
+ return value.toUpperCase();
+ });
+ ```
+
+ The above bound helper can be used inside of templates as follows:
+
+ ```handlebars
+ {{capitalize name}}
+ ```
+
+ In this case, when the `name` property of the template's context changes,
+ the rendered value of the helper will update to reflect this change.
+
+ ## Example with options
+
+ Like normal handlebars helpers, bound helpers have access to the options
+ passed into the helper call.
+
+ ```javascript
+ Ember.Handlebars.registerBoundHelper('repeat', function(value, options) {
+ var count = options.hash.count;
+ var a = [];
+ while(a.length < count) {
+ a.push(value);
+ }
+ return a.join('');
+ });
+ ```
+
+ This helper could be used in a template as follows:
+
+ ```handlebars
+ {{repeat text count=3}}
+ ```
+
+ ## Example with bound options
+
+ Bound hash options are also supported. Example:
+
+ ```handlebars
+ {{repeat text countBinding="numRepeats"}}
+ ```
+
+ In this example, count will be bound to the value of
+ the `numRepeats` property on the context. If that property
+ changes, the helper will be re-rendered.
+
+ ## Example with extra dependencies
+
+ The `Ember.Handlebars.registerBoundHelper` method takes a variable length
+ third parameter which indicates extra dependencies on the passed in value.
+ This allows the handlebars helper to update when these dependencies change.
+
+ ```javascript
+ Ember.Handlebars.registerBoundHelper('capitalizeName', function(value) {
+ return value.get('name').toUpperCase();
+ }, 'name');
+ ```
+
+ ## Example with multiple bound properties
+
+ `Ember.Handlebars.registerBoundHelper` supports binding to
+ multiple properties, e.g.:
+
+ ```javascript
+ Ember.Handlebars.registerBoundHelper('concatenate', function() {
+ var values = Array.prototype.slice.call(arguments, 0, -1);
+ return values.join('||');
+ });
+ ```
+
+ Which allows for template syntax such as `{{concatenate prop1 prop2}}` or
+ `{{concatenate prop1 prop2 prop3}}`. If any of the properties change,
+ the helpr will re-render. Note that dependency keys cannot be
+ using in conjunction with multi-property helpers, since it is ambiguous
+ which property the dependent keys would belong to.
+
+ ## Use with unbound helper
+
+ The `{{unbound}}` helper can be used with bound helper invocations
+ to render them in their unbound form, e.g.
+
+ ```handlebars
+ {{unbound capitalize name}}
+ ```
+
+ In this example, if the name property changes, the helper
+ will not re-render.
+
+ ## Use with blocks not supported
+
+ Bound helpers do not support use with Handlebars blocks or
+ the addition of child views of any kind.

+ Use the `{{with}}` helper when you want to scope context. Take the following code as an example:

+ <h6>{{user.role.label}}</h6>
+ <span class="role-id">{{user.role.id}}</span>
+
+ <p class="role-desc">{{user.role.description}}</p>
+ </div>
+ ```
+
+ `{{with}}` can be our best friend in these cases,
+ instead of writing `user.role.*` over and over, we use `{{#with user.role}}`.
+ Now the context within the `{{#with}} .. {{/with}}` block is `user.role` so you can do the following:
+
+ ```handlebars
+ <h5>{{user.name}}</h5>
+
+ <div class="role">
+ {{#with user.role}}
+ <h6>{{label}}</h6>
+ <span class="role-id">{{id}}</span>
+
+ <p class="role-desc">{{description}}</p>
+ {{/with}}
+ </div>
+ ```
+
+ ### `as` operator
+
+ This operator aliases the scope to a new name. It's helpful for semantic clarity and to retain
+ default scope or to reference from another `{{with}}` block.
+
+ ```handlebars
+ // posts might not be
+ {{#with user.posts as blogPosts}}
+ <div class="notice">
+ There are {{blogPosts.length}} blog posts written by {{user.name}}.
+ </div>
+
+ {{#each post in blogPosts}}
+ <li>{{post.title}}</li>
+ {{/each}}
+ {{/with}}
+ ```
+
+ Without the `as` operator, it would be impossible to reference `user.name` in the example above.

+ `bind-attr` allows you to create a binding between DOM element attributes and
+ Ember objects. For example:
+
+ ```handlebars
+ <img {{bind-attr src="imageUrl" alt="imageTitle"}}>
+ ```
+
+ The above handlebars template will fill the `<img>`'s `src` attribute will
+ the value of the property referenced with `"imageUrl"` and its `alt`
+ attribute with the value of the property referenced with `"imageTitle"`.
+
+ If the rendering context of this template is the following object:
+
+ ```javascript
+ {
+ imageUrl: 'http://lolcats.info/haz-a-funny',
+ imageTitle: 'A humorous image of a cat'
+ }
+ ```
+
+ The resulting HTML output will be:
+
+ ```html
+ <img src="http://lolcats.info/haz-a-funny" alt="A humorous image of a cat">
+ ```
+
+ `bind-attr` cannot redeclare existing DOM element attributes. The use of `src`
+ in the following `bind-attr` example will be ignored and the hard coded value
+ of `src="/failwhale.gif"` will take precedence:
+
+ ```handlebars
+ <img src="/failwhale.gif" {{bind-attr src="imageUrl" alt="imageTitle"}}>
+ ```
+
+ ### `bind-attr` and the `class` attribute
+
+ `bind-attr` supports a special syntax for handling a number of cases unique
+ to the `class` DOM element attribute. The `class` attribute combines
+ multiple discrete values into a single attribute as a space-delimited
+ list of strings. Each string can be:
+
+ * a string return value of an object's property.
+ * a boolean return value of an object's property
+ * a hard-coded value
+
+ A string return value works identically to other uses of `bind-attr`. The
+ return value of the property will become the value of the attribute. For
+ example, the following view and template:
+
+ ```javascript
+ AView = Ember.View.extend({
+ someProperty: function() {
+ return "aValue";
+ }.property()
+ })
+ ```
+
+ ```handlebars
+ <img {{bind-attr class="view.someProperty}}>
+ ```
+
+ Result in the following rendered output:
+
+ ```html
+ <img class="aValue">
+ ```
+
+ A boolean return value will insert a specified class name if the property
+ returns `true` and remove the class name if the property returns `false`.
+
+ A class name is provided via the syntax
+ `somePropertyName:class-name-if-true`.
+
+ ```javascript
+ AView = Ember.View.extend({
+ someBool: true
+ })
+ ```
+
+ ```handlebars
+ <img {{bind-attr class="view.someBool:class-name-if-true"}}>
+ ```
+
+ Result in the following rendered output:
+
+ ```html
+ <img class="class-name-if-true">
+ ```
+
+ An additional section of the binding can be provided if you want to
+ replace the existing class instead of removing it when the boolean
+ value changes:
+
+ ```handlebars
+ <img {{bind-attr class="view.someBool:class-name-if-true:class-name-if-false"}}>
+ ```
+
+ A hard-coded value can be used by prepending `:` to the desired
+ class name: `:class-name-to-always-apply`.
+
+ ```handlebars
+ <img {{bind-attr class=":class-name-to-always-apply"}}>
+ ```
+
+ Results in the following rendered output:
+
+ ```html
+ <img class="class-name-to-always-apply">
+ ```
+
+ All three strategies - string return value, boolean return value, and
+ hard-coded value ��� can be combined in a single declaration:
+
+ ```handlebars
+ <img {{bind-attr class=":class-name-to-always-apply view.someBool:class-name-if-true view.someProperty"}}>
+ ```

+ `{{view}}` inserts a new instance of `Ember.View` into a template passing its

+
+ An empty `<body>` and the following template:
+
+ ```handlebars
+ A span:
+ {{#view tagName="span"}}
+ hello.
+ {{/view}}
+ ```
+
+ Will result in HTML structure:
+
+ ```html
+ <body>
+ <!-- Note: the handlebars template script
+ also results in a rendered Ember.View
+ which is the outer <div> here -->
+
+ <div class="ember-view">
+ A span:
+ <span id="ember1" class="ember-view">
+ Hello.
+ </span>
+ </div>
+ </body>
+ ```
+
+ ### `parentView` setting
+
+ The `parentView` property of the new `Ember.View` instance created through
+ `{{view}}` will be set to the `Ember.View` instance of the template where
+ `{{view}}` was called.
+
+ ```javascript
+ aView = Ember.View.create({
+ template: Ember.Handlebars.compile("{{#view}} my parent: {{parentView.elementId}} {{/view}}")
+ });
+
+ aView.appendTo('body');
+ ```
+
+ Will result in HTML structure:
+
+ ```html
+ <div id="ember1" class="ember-view">
+ <div id="ember2" class="ember-view">
+ my parent: ember1
+ </div>
+ </div>
+ ```
+
+ ### Setting CSS id and class attributes
+
+ The HTML `id` attribute can be set on the `{{view}}`'s resulting element with
+ the `id` option. This option will _not_ be passed to `Ember.View.create`.
+
+ ```handlebars
+ {{#view tagName="span" id="a-custom-id"}}
+ hello.
+ {{/view}}
+ ```
+
+ Results in the following HTML structure:
+
+ ```html
+ <div class="ember-view">
+ <span id="a-custom-id" class="ember-view">
+ hello.
+ </span>
+ </div>
+ ```
+
+ The HTML `class` attribute can be set on the `{{view}}`'s resulting element
+ with the `class` or `classNameBindings` options. The `class` option will
+ directly set the CSS `class` attribute and will not be passed to
+ `Ember.View.create`. `classNameBindings` will be passed to `create` and use
+ `Ember.View`'s class name binding functionality:
+
+ ```handlebars
+ {{#view tagName="span" class="a-custom-class"}}
+ hello.
+ {{/view}}
+ ```
+
+ Results in the following HTML structure:
+
+ ```html
+ <div class="ember-view">
+ <span id="ember2" class="ember-view a-custom-class">
+ hello.
+ </span>
+ </div>
+ ```
+
+ ### Supplying a different view class
+
+ `{{view}}` can take an optional first argument before its supplied options to
+ specify a path to a custom view class.
+
+ ```handlebars
+ {{#view "MyApp.CustomView"}}
+ hello.
+ {{/view}}
+ ```
+
+ The first argument can also be a relative path accessible from the current
+ context.
+
+ ```javascript
+ MyApp = Ember.Application.create({});
+ MyApp.OuterView = Ember.View.extend({
+ innerViewClass: Ember.View.extend({
+ classNames: ['a-custom-view-class-as-property']
+ }),
+ template: Ember.Handlebars.compile('{{#view "view.innerViewClass"}} hi {{/view}}')
+ });
+
+ MyApp.OuterView.create().appendTo('body');
+ ```
+
+ Will result in the following HTML:
+
+ ```html
+ <div id="ember1" class="ember-view">
+ <div id="ember2" class="ember-view a-custom-view-class-as-property">
+ hi
+ </div>
+ </div>
+ ```
+
+ ### Blockless use
+
+ If you supply a custom `Ember.View` subclass that specifies its own template
+ or provide a `templateName` option to `{{view}}` it can be used without
+ supplying a block. Attempts to use both a `templateName` option and supply a
+ block will throw an error.
+
+ ```handlebars
+ {{view "MyApp.ViewWithATemplateDefined"}}
+ ```
+
+ ### `viewName` property
+
+ You can supply a `viewName` option to `{{view}}`. The `Ember.View` instance
+ will be referenced as a property of its parent view by this name.
+
+ ```javascript
+ aView = Ember.View.create({
+ template: Ember.Handlebars.compile('{{#view viewName="aChildByName"}} hi {{/view}}')
+ });
+
+ aView.appendTo('body');
+ aView.get('aChildByName') // the instance of Ember.View created by {{view}} helper
+ ```

+ if (path && path.data && path.data.isRenderData) {

+ `{{collection}}` is a `Ember.Handlebars` helper for adding instances of
+ `Ember.CollectionView` to a template. See [Ember.CollectionView](/api/classes/Ember.CollectionView.html)
+ for additional information on how a `CollectionView` functions.
+
+ `{{collection}}`'s primary use is as a block helper with a `contentBinding`
+ option pointing towards an `Ember.Array`-compatible object. An `Ember.View`
+ instance will be created for each item in its `content` property. Each view
+ will have its own `content` property set to the appropriate item in the
+ collection.
+
+ The provided block will be applied as the template for each item's view.
+
+ Given an empty `<body>` the following template:
+
+ ```handlebars
+ {{#collection contentBinding="App.items"}}
+ Hi {{view.content.name}}
+ {{/collection}}
+ ```
+
+ And the following application code
+
+ ```javascript
+ App = Ember.Application.create()
+ App.items = [
+ Ember.Object.create({name: 'Dave'}),
+ Ember.Object.create({name: 'Mary'}),
+ Ember.Object.create({name: 'Sara'})
+ ]
+ ```
+
+ Will result in the HTML structure below
+
+ ```html
+ <div class="ember-view">
+ <div class="ember-view">Hi Dave</div>
+ <div class="ember-view">Hi Mary</div>
+ <div class="ember-view">Hi Sara</div>
+ </div>
+ ```
+
+ ### Blockless Use
+
+ If you provide an `itemViewClass` option that has its own `template` you can
+ omit the block.
+
+ The following template:
+
+ ```handlebars
+ {{collection contentBinding="App.items" itemViewClass="App.AnItemView"}}
+ ```
+
+ And application code
+
+ ```javascript
+ App = Ember.Application.create();
+ App.items = [
+ Ember.Object.create({name: 'Dave'}),
+ Ember.Object.create({name: 'Mary'}),
+ Ember.Object.create({name: 'Sara'})
+ ];
+
+ App.AnItemView = Ember.View.extend({
+ template: Ember.Handlebars.compile("Greetings {{view.content.name}}")
+ });
+ ```
+
+ Will result in the HTML structure below
+
+ ```html
+ <div class="ember-view">
+ <div class="ember-view">Greetings Dave</div>
+ <div class="ember-view">Greetings Mary</div>
+ <div class="ember-view">Greetings Sara</div>
+ </div>
+ ```
+
+ ### Specifying a CollectionView subclass
+
+ By default the `{{collection}}` helper will create an instance of
+ `Ember.CollectionView`. You can supply a `Ember.CollectionView` subclass to
+ the helper by passing it as the first argument:
+
+ ```handlebars
+ {{#collection App.MyCustomCollectionClass contentBinding="App.items"}}
+ Hi {{view.content.name}}
+ {{/collection}}
+ ```
+
+ ### Forwarded `item.*`-named Options
+
+ As with the `{{view}}`, helper options passed to the `{{collection}}` will be
+ set on the resulting `Ember.CollectionView` as properties. Additionally,
+ options prefixed with `item` will be applied to the views rendered for each
+ item (note the camelcasing):
+
+ ```handlebars
+ {{#collection contentBinding="App.items"
+ itemTagName="p"
+ itemClassNames="greeting"}}
+ Howdy {{view.content.name}}
+ {{/collection}}
+ ```
+
+ Will result in the following HTML structure:
+
+ ```html
+ <div class="ember-view">
+ <p class="ember-view greeting">Howdy Dave</p>
+ <p class="ember-view greeting">Howdy Mary</p>
+ <p class="ember-view greeting">Howdy Sara</p>
+ </div>
+ ```

+/**
+ The `{{#each}}` helper loops over elements in a collection, rendering its
+ block once for each item. It is an extension of the base Handlebars `{{#each}}`
+ helper:
+
+ ```javascript
+ Developers = [{name: 'Yehuda'},{name: 'Tom'}, {name: 'Paul'}];
+ ```
+
+ ```handlebars
+ {{#each Developers}}
+ {{name}}
+ {{/each}}
+ ```
+
+ `{{each}}` supports an alternative syntax with element naming:
+
+ ```handlebars
+ {{#each person in Developers}}
+ {{person.name}}
+ {{/each}}
+ ```
+
+ When looping over objects that do not have properties, `{{this}}` can be used
+ to render the object:
+
+ ```javascript
+ DeveloperNames = ['Yehuda', 'Tom', 'Paul']
+ ```
+
+ ```handlebars
+ {{#each DeveloperNames}}
+ {{this}}
+ {{/each}}
+ ```
+ ### {{else}} condition
+ `{{#each}}` can have a matching `{{else}}`. The contents of this block will render
+ if the collection is empty.
+
+ ```
+ {{#each person in Developers}}
+ {{person.name}}
+ {{else}}
+ <p>Sorry, nobody is available for this task.</p>
+ {{/each}}
+ ```
+ ### Specifying a View class for items
+ If you provide an `itemViewClass` option that references a view class
+ with its own `template` you can omit the block.
+
+ The following template:
+
+ ```handlebars
+ {{#view App.MyView }}
+ {{each view.items itemViewClass="App.AnItemView"}}
+ {{/view}}
+ ```
+
+ And application code
+
+ ```javascript
+ App = Ember.Application.create({
+ MyView: Ember.View.extend({
+ items: [
+ Ember.Object.create({name: 'Dave'}),
+ Ember.Object.create({name: 'Mary'}),
+ Ember.Object.create({name: 'Sara'})
+ ]
+ })
+ });
+
+ App.AnItemView = Ember.View.extend({
+ template: Ember.Handlebars.compile("Greetings {{name}}")
+ });
+ ```
+
+ Will result in the HTML structure below
+
+ ```html
+ <div class="ember-view">
+ <div class="ember-view">Greetings Dave</div>
+ <div class="ember-view">Greetings Mary</div>
+ <div class="ember-view">Greetings Sara</div>
+ </div>
+ ```
+
+ If an `itemViewClass` is defined on the helper, and therefore the helper is not
+ being used as a block, an `emptyViewClass` can also be provided optionally.
+ The `emptyViewClass` will match the behavior of the `{{else}}` condition
+ described above. That is, the `emptyViewClass` will render if the collection
+ is empty.
+
+ ### Representing each item with a Controller.
+ By default the controller lookup within an `{{#each}}` block will be
+ the controller of the template where the `{{#each}}` was used. If each
+ item needs to be presented by a custom controller you can provide a
+ `itemController` option which references a controller by lookup name.
+ Each item in the loop will be wrapped in an instance of this controller
+ and the item itself will be set to the `content` property of that controller.
+
+ This is useful in cases where properties of model objects need transformation
+ or synthesis for display:
+
+ ```javascript
+ App.DeveloperController = Ember.ObjectController.extend({
+ isAvailableForHire: function() {
+ return !this.get('content.isEmployed') && this.get('content.isSeekingWork');
+ }.property('isEmployed', 'isSeekingWork')
+ })
+ ```
+
+ ```handlebars
+ {{#each person in developers itemController="developer"}}
+ {{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}}
+ {{/each}}
+ ```
+
+ Each itemController will receive a reference to the current controller as
+ a `parentController` property.
+
+ ### (Experimental) Grouped Each
+
+ When used in conjunction with the experimental [group helper](https://github.com/emberjs/group-helper),
+ you can inform Handlebars to re-render an entire group of items instead of
+ re-rendering them one at a time (in the event that they are changed en masse
+ or an item is added/removed).
+
+ ```handlebars
+ {{#group}}
+ {{#each people}}
+ {{firstName}} {{lastName}}
+ {{/each}}
+ {{/group}}
+ ```
+
+ This can be faster than the normal way that Handlebars re-renders items
+ in some cases.
+
+ If for some reason you have a group with more than one `#each`, you can make
+ one of the collections be updated in normal (non-grouped) fashion by setting
+ the option `groupedRows=true` (counter-intuitive, I know).
+
+ For example,
+
+ ```handlebars
+ {{dealershipName}}
+
+ {{#group}}
+ {{#each dealers}}
+ {{firstName}} {{lastName}}
+ {{/each}}
+
+ {{#each car in cars groupedRows=true}}
+ {{car.make}} {{car.model}} {{car.color}}
+ {{/each}}
+ {{/group}}
+ ```
+ Any change to `dealershipName` or the `dealers` collection will cause the
+ entire group to be re-rendered. However, changes to the `cars` collection
+ will be re-rendered individually (as normal).
+
+ Note that `group` behavior is also disabled by specifying an `itemViewClass`.

+ {{#with loggedInUser}}
+ Last Login: {{lastLogin}}

+ When used in a Handlebars template that is assigned to an `Ember.View`
+ instance's `layout` property Ember will render the layout template first,
+ inserting the view's own rendered output at the `{{yield}}` location.
+
+ An empty `<body>` and the following application code:
+
+ ```javascript

+ </div>

+ <!-- application.hbs -->
+ {{#labeled-textfield value=someProperty}}

+/**
+ The `Ember.Select` view class renders a
+ [select](https://developer.mozilla.org/en/HTML/Element/select) HTML element,
+ allowing the user to choose from a list of options.
+
+ The text and `value` property of each `<option>` element within the
+ `<select>` element are populated from the objects in the `Element.Select`'s
+ `content` property. The underlying data object of the selected `<option>` is
+ stored in the `Element.Select`'s `value` property.
+
+ ## The Content Property (array of strings)
+
+ The simplest version of an `Ember.Select` takes an array of strings as its
+ `content` property. The string will be used as both the `value` property and
+ the inner text of each `<option>` element inside the rendered `<select>`.
+
+ Example:
+
+ ```javascript
+ App.ApplicationController = Ember.Controller.extend({
+ names: ["Yehuda", "Tom"]
+ });
+ ```
+
+ ```handlebars
+ {{view Ember.Select content=names}}
+ ```
+
+ Would result in the following HTML:
+
+ ```html
+ <select class="ember-select">
+ <option value="Yehuda">Yehuda</option>
+ <option value="Tom">Tom</option>
+ </select>
+ ```
+
+ You can control which `<option>` is selected through the `Ember.Select`'s
+ `value` property:
+
+ ```javascript
+ App.ApplicationController = Ember.Controller.extend({
+ selectedName: 'Tom',
+ names: ["Yehuda", "Tom"]
+ });
+ ```
+
+ ```handlebars
+ {{view Ember.Select
+ content=names
+ value=selectedName
+ }}
+ ```
+
+ Would result in the following HTML with the `<option>` for 'Tom' selected:
+
+ ```html
+ <select class="ember-select">
+ <option value="Yehuda">Yehuda</option>
+ <option value="Tom" selected="selected">Tom</option>
+ </select>
+ ```
+
+ A user interacting with the rendered `<select>` to choose "Yehuda" would
+ update the value of `selectedName` to "Yehuda".
+
+ ## The Content Property (array of Objects)
+
+ An `Ember.Select` can also take an array of JavaScript or Ember objects as
+ its `content` property.
+
+ When using objects you need to tell the `Ember.Select` which property should
+ be accessed on each object to supply the `value` attribute of the `<option>`
+ and which property should be used to supply the element text.
+
+ The `optionValuePath` option is used to specify the path on each object to
+ the desired property for the `value` attribute. The `optionLabelPath`
+ specifies the path on each object to the desired property for the
+ element's text. Both paths must reference each object itself as `content`:
+
+ ```javascript
+ App.ApplicationController = Ember.Controller.extend({
+ programmers: [
+ {firstName: "Yehuda", id: 1},
+ {firstName: "Tom", id: 2}
+ ]
+ });
+ ```
+
+ ```handlebars
+ {{view Ember.Select
+ content=programmers
+ optionValuePath="content.id"
+ optionLabelPath="content.firstName"}}
+ ```
+
+ Would result in the following HTML:
+
+ ```html
+ <select class="ember-select">
+ <option value="1">Yehuda</option>
+ <option value="2">Tom</option>
+ </select>
+ ```
+
+ The `value` attribute of the selected `<option>` within an `Ember.Select`
+ can be bound to a property on another object:
+
+ ```javascript
+ App.ApplicationController = Ember.Controller.extend({
+ programmers: [
+ {firstName: "Yehuda", id: 1},
+ {firstName: "Tom", id: 2}
+ ],
+ currentProgrammer: {
+ id: 2
+ }
+ });
+ ```
+
+ ```handlebars
+ {{view Ember.Select
+ content=programmers
+ optionValuePath="content.id"
+ optionLabelPath="content.firstName"
+ value=currentProgrammer.id}}
+ ```
+
+ Would result in the following HTML with a selected option:
+
+ ```html
+ <select class="ember-select">
+ <option value="1">Yehuda</option>
+ <option value="2" selected="selected">Tom</option>
+ </select>
+ ```
+
+ Interacting with the rendered element by selecting the first option
+ ('Yehuda') will update the `id` of `currentProgrammer`
+ to match the `value` property of the newly selected `<option>`.
+
+ Alternatively, you can control selection through the underlying objects
+ used to render each object by binding the `selection` option. When the selected
+ `<option>` is changed, the property path provided to `selection`
+ will be updated to match the content object of the rendered `<option>`
+ element:
+
+ ```javascript
+ App.ApplicationController = Ember.Controller.extend({
+ selectedPerson: null,
+ programmers: [
+ {firstName: "Yehuda", id: 1},
+ {firstName: "Tom", id: 2}
+ ]
+ });
+ ```
+
+ ```handlebars
+ {{view Ember.Select
+ content=programmers
+ optionValuePath="content.id"
+ optionLabelPath="content.firstName"
+ selection=selectedPerson}}
+ ```
+
+ Would result in the following HTML with a selected option:
+
+ ```html
+ <select class="ember-select">
+ <option value="1">Yehuda</option>
+ <option value="2" selected="selected">Tom</option>
+ </select>
+ ```
+
+ Interacting with the rendered element by selecting the first option
+ ('Yehuda') will update the `selectedPerson` to match the object of
+ the newly selected `<option>`. In this case it is the first object
+ in the `programmers`
+
+ ## Supplying a Prompt
+
+ A `null` value for the `Ember.Select`'s `value` or `selection` property
+ results in there being no `<option>` with a `selected` attribute:
+
+ ```javascript
+ App.ApplicationController = Ember.Controller.extend({
+ selectedProgrammer: null,
+ programmers: [
+ "Yehuda",
+ "Tom"
+ ]
+ });
+ ```
+
+ ``` handlebars
+ {{view Ember.Select
+ content=programmers
+ value=selectedProgrammer
+ }}
+ ```
+
+ Would result in the following HTML:
+
+ ```html
+ <select class="ember-select">
+ <option value="Yehuda">Yehuda</option>
+ <option value="Tom">Tom</option>
+ </select>
+ ```
+
+ Although `selectedProgrammer` is `null` and no `<option>`
+ has a `selected` attribute the rendered HTML will display the
+ first item as though it were selected. You can supply a string
+ value for the `Ember.Select` to display when there is no selection
+ with the `prompt` option:
+
+ ```javascript
+ App.ApplicationController = Ember.Controller.extend({
+ selectedProgrammer: null,
+ programmers: [
+ "Yehuda",
+ "Tom"
+ ]
+ });
+ ```
+
+ ```handlebars
+ {{view Ember.Select
+ content=programmers
+ value=selectedProgrammer
+ prompt="Please select a name"
+ }}
+ ```
+
+ Would result in the following HTML:
+
+ ```html
+ <select class="ember-select">
+ <option>Please select a name</option>
+ <option value="Yehuda">Yehuda</option>
+ <option value="Tom">Tom</option>
+ </select>
+ ```

+/**
+
+ The `{{input}}` helper inserts an HTML `<input>` tag into the template,
+ with a `type` value of either `text` or `checkbox`. If no `type` is provided,
+ `text` will be the default value applied. The attributes of `{{input}}`
+ match those of the native HTML tag as closely as possible for these two types.
+
+ ## Use as text field
+ An `{{input}}` with no `type` or a `type` of `text` will render an HTML text input.
+ The following HTML attributes can be set via the helper:
+
+* `value`
+* `size`
+* `name`
+* `pattern`
+* `placeholder`
+* `disabled`
+* `maxlength`
+* `tabindex`
+
+
+ When set to a quoted string, these values will be directly applied to the HTML
+ element. When left unquoted, these values will be bound to a property on the
+ template's current rendering context (most typically a controller instance).
+
+ ## Unbound:
+
+ ```handlebars
+ {{input value="http://www.facebook.com"}}
+ ```
+
+
+ ```html
+ <input type="text" value="http://www.facebook.com"/>
+ ```
+
+ ## Bound:
+
+ ```javascript
+ App.ApplicationController = Ember.Controller.extend({
+ firstName: "Stanley",
+ entryNotAllowed: true
+ });
+ ```
+
+
+ ```handlebars
+ {{input type="text" value=firstName disabled=entryNotAllowed size="50"}}
+ ```
+
+
+ ```html
+ <input type="text" value="Stanley" disabled="disabled" size="50"/>
+ ```
+
+ ## Extension
+
+ Internally, `{{input type="text"}}` creates an instance of `Ember.TextField`, passing
+ arguments from the helper to `Ember.TextField`'s `create` method. You can extend the
+ capablilties of text inputs in your applications by reopening this class. For example,
+ if you are deploying to browsers where the `required` attribute is used, you
+ can add this to the `TextField`'s `attributeBindings` property:
+
+
+ ```javascript
+ Ember.TextField.reopen({
+ attributeBindings: ['required']
+ });
+ ```
+
+ Keep in mind when writing `Ember.TextField` subclasses that `Ember.TextField`
+ itself extends `Ember.Component`, meaning that it does NOT inherit
+ the `controller` of the parent view.
+
+ See more about [Ember components](api/classes/Ember.Component.html)
+
+
+ ## Use as checkbox
+
+ An `{{input}}` with a `type` of `checkbox` will render an HTML checkbox input.
+ The following HTML attributes can be set via the helper:
+
+* `checked`
+* `disabled`
+* `tabindex`
+* `indeterminate`
+* `name`
+
+
+ When set to a quoted string, these values will be directly applied to the HTML
+ element. When left unquoted, these values will be bound to a property on the
+ template's current rendering context (most typically a controller instance).
+
+ ## Unbound:
+
+ ```handlebars
+ {{input type="checkbox" name="isAdmin"}}
+ ```
+
+ ```html
+ <input type="checkbox" name="isAdmin" />
+ ```
+
+ ## Bound:
+
+ ```javascript
+ App.ApplicationController = Ember.Controller.extend({
+ isAdmin: true
+ });
+ ```
+
+
+ ```handlebars
+ {{input type="checkbox" checked=isAdmin }}
+ ```
+
+
+ ```html
+ <input type="checkbox" checked="checked" />
+ ```
+
+ ## Extension
+
+ Internally, `{{input type="checkbox"}}` creates an instance of `Ember.Checkbox`, passing
+ arguments from the helper to `Ember.Checkbox`'s `create` method. You can extend the
+ capablilties of checkbox inputs in your applications by reopening this class. For example,
+ if you wanted to add a css class to all checkboxes in your application:
+
+
+ ```javascript
+ Ember.Checkbox.reopen({
+ classNames: ['my-app-checkbox']
+ });
+ ```
+
+
+ @method input
+ @for Ember.Handlebars.helpers
+ @param {Hash} options
+*/
+Ember.Handlebars.registerHelper('input', function(options) {
+ Ember.assert('You can only pass attributes to the `input` helper, not arguments', arguments.length < 2);
+
+ var hash = options.hash,
+ types = options.hashTypes,
+ inputType = hash.type,
+ onEvent = hash.on;
+
+ delete hash.type;
+ delete hash.on;
+
+ if (inputType === 'checkbox') {

+ } else {

+ return Ember.Handlebars.helpers.view.call(this, Ember.TextField, options);
+ }
+});
+
+/**
+ `{{textarea}}` inserts a new instance of `<textarea>` tag into the template.
+ The attributes of `{{textarea}}` match those of the native HTML tags as
+ closely as possible.
+
+ The following HTML attributes can be set:
+
+ * `value`
+ * `name`
+ * `rows`
+ * `cols`
+ * `placeholder`
+ * `disabled`
+ * `maxlength`
+ * `tabindex`
+
+ When set to a quoted string, these value will be directly applied to the HTML
+ element. When left unquoted, these values will be bound to a property on the
+ template's current rendering context (most typically a controller instance).
+
+ Unbound:
+
+ ```handlebars
+ {{textarea value="Lots of static text that ISN'T bound"}}
+ ```
+
+ Would result in the following HTML:
+
+ ```html
+ <textarea class="ember-text-area">
+ Lots of static text that ISN'T bound
+ </textarea>
+ ```
+
+ Bound:
+
+ In the following example, the `writtenWords` property on `App.ApplicationController`
+ will be updated live as the user types 'Lots of text that IS bound' into
+ the text area of their browser's window.
+
+ ```javascript
+ App.ApplicationController = Ember.Controller.extend({
+ writtenWords: "Lots of text that IS bound"
+ });
+ ```
+
+ ```handlebars
+ {{textarea value=writtenWords}}
+ ```
+
+ Would result in the following HTML:
+
+ ```html
+ <textarea class="ember-text-area">
+ Lots of text that IS bound
+ </textarea>
+ ```
+
+ If you wanted a one way binding between the text area and a div tag
+ somewhere else on your screen, you could use `Ember.computed.oneWay`:
+
+ ```javascript
+ App.ApplicationController = Ember.Controller.extend({
+ writtenWords: "Lots of text that IS bound",
+ outputWrittenWords: Ember.computed.oneWay("writtenWords")
+ });
+ ```
+
+ ```handlebars
+ {{textarea value=writtenWords}}
+
+ <div>
+ {{outputWrittenWords}}
+ </div>
+ ```
+
+ Would result in the following HTML:
+
+ ```html
+ <textarea class="ember-text-area">
+ Lots of text that IS bound
+ </textarea>
+
+ <-- the following div will be updated in real time as you type -->
+
+ <div>
+ Lots of text that IS bound
+ </div>
+ ```
+
+ Finally, this example really shows the power and ease of Ember when two
+ properties are bound to eachother via `Ember.computed.alias`. Type into
+ either text area box and they'll both stay in sync. Note that
+ `Ember.computed.alias` costs more in terms of performance, so only use it when
+ your really binding in both directions:
+
+ ```javascript
+ App.ApplicationController = Ember.Controller.extend({
+ writtenWords: "Lots of text that IS bound",
+ twoWayWrittenWords: Ember.computed.alias("writtenWords")
+ });
+ ```
+
+ ```handlebars
+ {{textarea value=writtenWords}}
+ {{textarea value=twoWayWrittenWords}}
+ ```
+
+ ```html
+ <textarea id="ember1" class="ember-text-area">
+ Lots of text that IS bound
+ </textarea>
+
+ <-- both updated in real time -->
+
+ <textarea id="ember2" class="ember-text-area">
+ Lots of text that IS bound
+ </textarea>
+ ```
+
+ ## Extension
+
+ Internally, `{{textarea}}` creates an instance of `Ember.TextArea`, passing

+ extend the capabilities of text areas in your application by reopening this
+ class. For example, if you are deploying to browsers where the `required`
+ attribute is used, you can globally add support for the `required` attribute
+ on all `{{textarea}}`s' in your app by reopening `Ember.TextArea` or
+ `Ember.TextSupport` and adding it to the `attributeBindings` concatenated
+ property:
+
+ ```javascript

+ The collection of functions, keyed by name, available on this route as

+
+ These functions will be invoked when a matching `{{action}}` is triggered
+ from within a template and the application's current route is this route.
+
+ Actions can also be invoked from other parts of your application via `Route#send`
+ or `Controller#send`.
+
+ The `actions` hash will inherit action handlers from
+ the `actions` hash defined on extended Route parent classes
+ or mixins rather than just replace the entire hash, e.g.:
+
+ ```js
+ App.CanDisplayBanner = Ember.Mixin.create({
+ actions: {
+ displayBanner: function(msg) {
+ // ...
+ }
+ }
+ });
+
+ App.WelcomeRoute = Ember.Route.extend(App.CanDisplayBanner, {
+ actions: {
+ playMusic: function() {
+ // ...
+ }
+ }
+ });
+
+ // `WelcomeRoute`, when active, will be able to respond
+ // to both actions, since the actions hash is merged rather
+ // then replaced when extending mixins / parent classes.
+ this.send('displayBanner');
+ this.send('playMusic');
+ ```
+
+ Within a route's action handler, the value of the `this` context
+ is the Route object:
+
+ ```js
+ App.SongRoute = Ember.Route.extend({
+ actions: {
+ myAction: function() {
+ this.controllerFor("song");
+ this.transitionTo("other.route");
+ ...
+ }
+ }
+ });
+ ```
+
+ It is also possible to call `this._super()` from within an
+ action handler if it overrides a handler defined on a parent
+ class or mixin:
+
+ Take for example the following routes:
+
+ ```js
+ App.DebugRoute = Ember.Mixin.create({
+ actions: {
+ debugRouteInformation: function() {
+ console.debug("trololo");
+ }
+ }
+ });
+
+ App.AnnoyingDebugRoute = Ember.Route.extend(App.DebugRoute, {
+ actions: {
+ debugRouteInformation: function() {
+ // also call the debugRouteInformation of mixed in App.DebugRoute
+ this._super();
+
+ // show additional annoyance
+ window.alert(...);
+ }
+ }
+ });
+ ```
+
+ ## Bubbling
+
+ By default, an action will stop bubbling once a handler defined
+ on the `actions` hash handles it. To continue bubbling the action,
+ you must return `true` from the handler:
+
+ ```js
+ App.Router.map(function() {
+ this.resource("album", function() {
+ this.route("song");
+ });
+ });
+
+ App.AlbumRoute = Ember.Route.extend({
+ actions: {
+ startPlaying: function() {
+ }
+ }
+ });
+
+ App.AlbumSongRoute = Ember.Route.extend({
+ actions: {
+ startPlaying: function() {
+ // ...
+
+ if (actionShouldAlsoBeTriggeredOnParentRoute) {
+ return true;
+ }
+ }
+ }
+ });
+ ```
+
+ ## Built-in actions
+
+ There are a few built-in actions pertaining to transitions that you
+ can use to customize transition behavior: `willTransition` and
+ `error`.
+
+ ### `willTransition`
+
+ The `willTransition` action is fired at the beginning of any
+ attempted transition with a `Transition` object as the sole
+ argument. This action can be used for aborting, redirecting,
+ or decorating the transition from the currently active routes.
+
+ A good example is preventing navigation when a form is
+ half-filled out:
+
+ ```js
+ App.ContactFormRoute = Ember.Route.extend({
+ actions: {
+ willTransition: function(transition) {
+ if (this.controller.get('userHasEnteredData')) {
+ this.controller.displayNavigationConfirm();
+ transition.abort();
+ }
+ }
+ }
+ });
+ ```
+
+ You can also redirect elsewhere by calling
+ `this.transitionTo('elsewhere')` from within `willTransition`.
+ Note that `willTransition` will not be fired for the
+ redirecting `transitionTo`, since `willTransition` doesn't
+ fire when there is already a transition underway. If you want
+ subsequent `willTransition` actions to fire for the redirecting
+ transition, you must first explicitly call
+ `transition.abort()`.
+
+ ### `error`
+
+ When attempting to transition into a route, any of the hooks
+ may return a promise that rejects, at which point an `error`
+ action will be fired on the partially-entered routes, allowing
+ for per-route error handling logic, or shared error handling
+ logic defined on a parent route.
+
+ Here is an example of an error handler that will be invoked
+ for rejected promises from the various hooks on the route,
+ as well as any unhandled errors from child routes:
+
+ ```js
+ App.AdminRoute = Ember.Route.extend({
+ beforeModel: function() {
+ return Ember.RSVP.reject("bad things!");
+ },
+
+ actions: {
+ error: function(error, transition) {
+ // Assuming we got here due to the error in `beforeModel`,
+ // we can expect that error === "bad things!",
+ // but a promise model rejecting would also
+ // call this hook, as would any errors encountered
+ // in `afterModel`.
+
+ // The `error` hook is also provided the failed
+ // `transition`, which can be stored and later
+ // `.retry()`d if desired.
+
+ this.transitionTo('login');
+ }
+ }
+ });
+ ```
+
+ `error` actions that bubble up all the way to `ApplicationRoute`
+ will fire a default error handler that logs the error. You can
+ specify your own global default error handler by overriding the
+ `error` handler on `ApplicationRoute`:
+
+ ```js
+ App.ApplicationRoute = Ember.Route.extend({
+ actions: {
+ error: function(error, transition) {
+ this.controllerFor('banner').displayError(error.message);
+ }
+ }
+ });
+ ```
+

+ moveToSecret: function(context){
+ if (authorized()){
+ this.transitionTo('secret', context);
+ }
+ this.transitionTo('fourOhFour');
+ }
+ }
+ });
+ ```
+
+ Transition to a nested route
+
+ ```javascript
+ App.Router.map(function() {
+ this.resource('articles', { path: '/articles' }, function() {
+ this.route('new');
+ });
+ });
+
+ App.IndexRoute = Ember.Route.extend({
+ actions: {
+ transitionToNewArticle: function() {
+ this.transitionTo('articles.new');
+ }
+ }
+ });
+ ```
+
+ Multiple Models Example
+
+ ```javascript
+ App.Router.map(function() {
+ this.route("index");
+ this.resource('breakfast', {path:':breakfastId'}, function(){
+ this.resource('cereal', {path: ':cerealId'});
+ });
+ });
+

+
+ 1) A decision can be made to redirect elsewhere without
+ needing to resolve the model first.
+ 2) Any async operations need to occur first before the
+ model is attempted to be resolved.
+
+ This hook is provided the current `transition` attempt
+ as a parameter, which can be used to `.abort()` the transition,
+ save it for a later `.retry()`, or retrieve values set
+ on it from a previous hook. You can also just call
+ `this.transitionTo` to another route to implicitly
+ abort the `transition`.
+
+ You can return a promise from this hook to pause the
+ transition until the promise resolves (or rejects). This could
+ be useful, for instance, for retrieving async code from
+ the server that is required to enter a route.
+
+ ```js

+ If `App.Post` doesn't exist in the above example,
+ `beforeModel` will use jQuery's `getScript`, which
+ returns a promise that resolves after the server has
+ successfully retrieved and executed the code from the
+ server. Note that if an error were to occur, it would
+ be passed to the `error` hook on `Ember.Route`, but
+ it's also possible to handle errors specific to
+ `beforeModel` right from within the hook (to distinguish
+ from the shared error handling behavior of the `error`
+ hook):
+
+ ```js
+ App.PostRoute = Ember.Route.extend({

+ var self = this;
+ return Ember.$.getScript('post.js').then(null, function(e) {

+ // halt the transition. If you were to return

+ // error so that it'd be handled by the `error`
+ // hook, you would have to either

+ element:
+
+ ```handlebars
+ {{#link-to 'photoGallery'}}
+ Great Hamster Photos
+ {{/link-to}}
+ ```
+
+ ```html
+ <a href="/hamster-photos">
+ Great Hamster Photos
+ </a>
+ ```
+
+ ### Supplying a tagName
+ By default `{{link-to}}` renders an `<a>` element. This can
+ be overridden for a single use of `{{link-to}}` by supplying
+ a `tagName` option:
+
+ ```handlebars
+ {{#link-to 'photoGallery' tagName="li"}}
+ Great Hamster Photos
+ {{/link-to}}
+ ```
+
+ ```html
+ <li>
+ Great Hamster Photos
+ </li>
+ ```
+
+ To override this option for your entire application, see
+ "Overriding Application-wide Defaults".
+
+ ### Disabling the `link-to` helper
+ By default `{{link-to}}` is enabled.
+ any passed value to `disabled` helper property will disable the `link-to` helper.
+
+ static use: the `disabled` option:
+
+ ```handlebars
+ {{#link-to 'photoGallery' disabled=true}}
+ Great Hamster Photos
+ {{/link-to}}
+ ```
+
+ dynamic use: the `disabledWhen` option:
+
+ ```handlebars
+ {{#link-to 'photoGallery' disabledWhen=controller.someProperty}}
+ Great Hamster Photos
+ {{/link-to}}
+ ```
+
+ any passed value to `disabled` will disable it except `undefined`.
+ to ensure that only `true` disable the `link-to` helper you can
+ override the global behaviour of `Ember.LinkView`.
+
+ ```javascript
+ Ember.LinkView.reopen({
+ disabled: Ember.computed(function(key, value) {
+ if (value !== undefined) {
+ this.set('_isDisabled', value === true);
+ }
+ return value === true ? get(this, 'disabledClass') : false;
+ })
+ });
+ ```
+
+ see "Overriding Application-wide Defaults" for more.
+
+ ### Handling `href`
+ `{{link-to}}` will use your application's Router to
+ fill the element's `href` property with a url that
+ matches the path to the supplied `routeName` for your
+ routers's configured `Location` scheme, which defaults
+ to Ember.HashLocation.
+
+ ### Handling current route
+ `{{link-to}}` will apply a CSS class name of 'active'
+ when the application's current route matches
+ the supplied routeName. For example, if the application's
+ current route is 'photoGallery.recent' the following
+ use of `{{link-to}}`:
+
+ ```handlebars
+ {{#link-to 'photoGallery.recent'}}
+ Great Hamster Photos from the last week
+ {{/link-to}}
+ ```
+
+ will result in
+
+ ```html
+ <a href="/hamster-photos/this-week" class="active">
+ Great Hamster Photos
+ </a>
+ ```
+
+ The CSS class name used for active classes can be customized
+ for a single use of `{{link-to}}` by passing an `activeClass`
+ option:
+
+ ```handlebars
+ {{#link-to 'photoGallery.recent' activeClass="current-url"}}
+ Great Hamster Photos from the last week
+ {{/link-to}}
+ ```
+
+ ```html
+ <a href="/hamster-photos/this-week" class="current-url">
+ Great Hamster Photos
+ </a>
+ ```
+
+ To override this option for your entire application, see
+ "Overriding Application-wide Defaults".
+
+ ### Supplying a model
+ An optional model argument can be used for routes whose
+ paths contain dynamic segments. This argument will become
+ the model context of the linked route:
+
+ ```javascript
+ App.Router.map(function() {
+ this.resource("photoGallery", {path: "hamster-photos/:photo_id"});
+ });
+ ```
+
+ ```handlebars
+ {{#link-to 'photoGallery' aPhoto}}
+ {{aPhoto.title}}
+ {{/link-to}}
+ ```
+
+ ```html
+ <a href="/hamster-photos/42">
+ Tomster
+ </a>
+ ```
+
+ ### Supplying multiple models
+ For deep-linking to route paths that contain multiple
+ dynamic segments, multiple model arguments can be used.
+ As the router transitions through the route path, each
+ supplied model argument will become the context for the
+ route with the dynamic segments:
+
+ ```javascript
+ App.Router.map(function() {
+ this.resource("photoGallery", {path: "hamster-photos/:photo_id"}, function() {
+ this.route("comment", {path: "comments/:comment_id"});
+ });
+ });
+ ```
+ This argument will become the model context of the linked route:
+
+ ```handlebars
+ {{#link-to 'photoGallery.comment' aPhoto comment}}
+ {{comment.body}}
+ {{/link-to}}
+ ```
+
+ ```html
+ <a href="/hamster-photos/42/comment/718">
+ A+++ would snuggle again.
+ </a>
+ ```
+
+ ### Supplying an explicit dynamic segment value
+ If you don't have a model object available to pass to `{{link-to}}`,
+ an optional string or integer argument can be passed for routes whose
+ paths contain dynamic segments. This argument will become the value
+ of the dynamic segment:
+
+ ```javascript
+ App.Router.map(function() {
+ this.resource("photoGallery", {path: "hamster-photos/:photo_id"});
+ });
+ ```
+
+ ```handlebars
+ {{#link-to 'photoGallery' aPhotoId}}
+ {{aPhoto.title}}
+ {{/link-to}}
+ ```
+
+ ```html
+ <a href="/hamster-photos/42">
+ Tomster
+ </a>
+ ```
+
+ When transitioning into the linked route, the `model` hook will
+ be triggered with parameters including this passed identifier.
+
+ ### Allowing Default Action
+
+ By default the `{{link-to}}` helper prevents the default browser action
+ by calling `preventDefault()` as this sort of action bubbling is normally
+ handled internally and we do not want to take the browser to a new URL (for
+ example).
+
+ If you need to override this behavior specify `preventDefault=false` in
+ your template:
+
+ ```handlebars
+ {{#link-to 'photoGallery' aPhotoId preventDefault=false}}
+ {{aPhotoId.title}}
+ {{/link-to}}
+ ```
+
+ ### Overriding attributes
+ You can override any given property of the Ember.LinkView
+ that is generated by the `{{link-to}}` helper by passing
+ key/value pairs, like so:
+
+ ```handlebars
+ {{#link-to aPhoto tagName='li' title='Following this link will change your life' classNames='pic sweet'}}
+ Uh-mazing!
+ {{/link-to}}
+ ```
+
+ See [Ember.LinkView](/api/classes/Ember.LinkView.html) for a
+ complete list of overrideable properties. Be sure to also
+ check out inherited properties of `LinkView`.
+
+ ### Overriding Application-wide Defaults
+ ``{{link-to}}`` creates an instance of Ember.LinkView
+ for rendering. To override options for your entire
+ application, reopen Ember.LinkView and supply the
+ desired values:
+
+ ``` javascript
+ Ember.LinkView.reopen({
+ activeClass: "is-active",
+ tagName: 'li'
+ })
+ ```
+
+ It is also possible to override the default event in
+ this manner:
+
+ ``` javascript
+ Ember.LinkView.reopen({
+ eventName: 'customEventName'
+ });
+ ```
+
+ @method link-to
+ @for Ember.Handlebars.helpers
+ @param {String} routeName
+ @param {Object} [context]*
+ @param [options] {Object} Handlebars key/value pairs of options, you can override any property of Ember.LinkView

+ route's `renderTemplate` hook. The following will render the `favoritePost`
+ template into the `outlet`.
+
+ ``` javascript
+ App.PostsRoute = Ember.Route.extend({
+ renderTemplate: function() {
+ this.render('favoritePost');
+ }
+ });
+ ```
+
+ You can create custom named outlets for more control.
+
+ ``` handlebars
+ {{outlet 'favoritePost'}}
+ {{outlet 'posts'}}
+ ```
+
+ Then you can define what template is rendered into each outlet in your
+ route.
+
+
+ ``` javascript
+ App.PostsRoute = Ember.Route.extend({
+ renderTemplate: function() {
+ this.render('favoritePost', { outlet: 'favoritePost' });
+ this.render('posts', { outlet: 'posts' });
+ }
+ });
+ ```
+
+ You can specify the view that the outlet uses to contain and manage the
+ templates rendered into it.
+
+ ``` handlebars
+ {{outlet view='sectionContainer'}}
+ ```
+
+ ``` javascript
+ App.SectionContainer = Ember.ContainerView.extend({
+ tagName: 'section',
+ classNames: ['special']
+ });
+ ```

+ /**
+ The `{{action}}` helper registers an HTML element within a template for DOM
+ event handling and forwards that interaction to the templates's controller
+ or supplied `target` option (see 'Specifying a Target').
+
+ If the controller does not implement the event, the event is sent
+ to the current route, and it bubbles up the route hierarchy from there.
+
+ User interaction with that element will invoke the supplied action name on
+ the appropriate target.
+
+ Given the following application Handlebars template on the page
+
+ ```handlebars
+ <div {{action 'anActionName'}}>
+ click me
+ </div>
+ ```
+
+ And application code
+
+ ```javascript
+ App.ApplicationController = Ember.Controller.extend({
+ actions: {
+ anActionName: function() {
+ }
+ }
+ });
+ ```
+
+ Will result in the following rendered HTML
+
+ ```html
+ <div class="ember-view">
+ <div data-ember-action="1">
+ click me
+ </div>
+ </div>
+ ```
+
+ Clicking "click me" will trigger the `anActionName` action of the
+ `App.ApplicationController`. In this case, no additional parameters will be passed.
+
+ If you provide additional parameters to the helper:
+
+ ```handlebars
+ <button {{action 'edit' post}}>Edit</button>
+ ```
+
+ Those parameters will be passed along as arguments to the JavaScript
+ function implementing the action.
+
+ ### Event Propagation
+
+ Events triggered through the action helper will automatically have
+ `.preventDefault()` called on them. You do not need to do so in your event
+ handlers. If you need to allow event propagation (to handle file inputs for
+ example) you can supply the `preventDefault=false` option to the `{{action}}` helper:
+
+ ```handlebars
+ <div {{action "sayHello" preventDefault=false}}>
+ <input type="file" />
+ <input type="checkbox" />
+ </div>
+ ```
+
+ To disable bubbling, pass `bubbles=false` to the helper:
+
+ ```handlebars
+ <button {{action 'edit' post bubbles=false}}>Edit</button>
+ ```
+
+ If you need the default handler to trigger you should either register your
+ own event handler, or use event methods on your view class. See [Ember.View](/api/classes/Ember.View.html)
+ 'Responding to Browser Events' for more information.
+
+ ### Specifying DOM event type
+
+ By default the `{{action}}` helper registers for DOM `click` events. You can
+ supply an `on` option to the helper to specify a different DOM event name:
+
+ ```handlebars
+ <div {{action "anActionName" on="doubleClick"}}>
+ click me
+ </div>
+ ```
+
+ See `Ember.View` 'Responding to Browser Events' for a list of
+ acceptable DOM event names.
+
+ NOTE: Because `{{action}}` depends on Ember's event dispatch system it will
+ only function if an `Ember.EventDispatcher` instance is available. An
+ `Ember.EventDispatcher` instance will be created when a new `Ember.Application`
+ is created. Having an instance of `Ember.Application` will satisfy this
+ requirement.
+
+ ### Specifying whitelisted modifier keys
+
+ By default the `{{action}}` helper will ignore click event with pressed modifier
+ keys. You can supply an `allowedKeys` option to specify which keys should not be ignored.
+
+ ```handlebars
+ <div {{action "anActionName" allowedKeys="alt"}}>
+ click me
+ </div>
+ ```
+
+ This way the `{{action}}` will fire when clicking with the alt key pressed down.
+
+ Alternatively, supply "any" to the `allowedKeys` option to accept any combination of modifier keys.
+
+ ```handlebars
+ <div {{action "anActionName" allowedKeys="any"}}>
+ click me with any key pressed
+ </div>
+ ```
+
+ ### Specifying a Target
+
+ There are several possible target objects for `{{action}}` helpers:
+
+ In a typical Ember application, where views are managed through use of the
+ `{{outlet}}` helper, actions will bubble to the current controller, then
+ to the current route, and then up the route hierarchy.
+
+ Alternatively, a `target` option can be provided to the helper to change
+ which object will receive the method call. This option must be a path
+ to an object, accessible in the current context:
+
+ ```handlebars
+ {{! the application template }}
+ <div {{action "anActionName" target=view}}>
+ click me
+ </div>
+ ```
+
+ ```javascript
+ App.ApplicationView = Ember.View.extend({
+ actions: {
+ anActionName: function(){}
+ }
+ });
+
+ ```
+
+ ### Additional Parameters
+
+ You may specify additional parameters to the `{{action}}` helper. These
+ parameters are passed along as the arguments to the JavaScript function
+ implementing the action.
+
+ ```handlebars
+ {{#each person in people}}
+ <div {{action "edit" person}}>
+ click me
+ </div>
+ {{/each}}
+ ```
+
+ Clicking "click me" will trigger the `edit` method on the current controller
+ with the value of `person` as a parameter.

+
+ ## Implementations
+
+ You can pass an implementation name (`hash`, `history`, `none`) to force a
+ particular implementation to be used in your application.
+
+ ### HashLocation
+
+ Using `HashLocation` results in URLs with a `#` (hash sign) separating the
+ server side URL portion of the URL from the portion that is used by Ember.
+ This relies upon the `hashchange` event existing in the browser.
+
+ Example:
+
+ ```javascript
+ App.Router.map(function() {
+ this.resource('posts', function() {
+ this.route('new');
+ });
+ });
+
+ App.Router.reopen({
+ location: 'hash'
+ });
+ ```
+
+ This will result in a posts.new url of `/#/posts/new`.
+
+ ### HistoryLocation
+
+ Using `HistoryLocation` results in URLs that are indistinguishable from a
+ standard URL. This relies upon the browser's `history` API.
+
+ Example:
+
+ ```javascript
+ App.Router.map(function() {
+ this.resource('posts', function() {
+ this.route('new');
+ });
+ });
+
+ App.Router.reopen({
+ location: 'history'
+ });
+ ```
+
+ This will result in a posts.new url of `/posts/new`.
+
+ ### NoneLocation
+
+ Using `NoneLocation` causes Ember to not store the applications URL state
+ in the actual URL. This is generally used for testing purposes, and is one
+ of the changes made when calling `App.setupForTesting()`.
+
+ ## Location API
+
+ Each location implementation must provide the following methods:
+
+ * implementation: returns the string name used to reference the implementation.
+ * getURL: returns the current URL.
+ * setURL(path): sets the current URL.
+ * replaceURL(path): replace the current URL (optional).
+ * onUpdateURL(callback): triggers the callback when the URL changes.
+ * formatURL(url): formats `url` to be placed into `href` attribute.
+
+ Calling setURL or replaceURL will not trigger onUpdateURL callbacks.

+/**
+ The DefaultResolver defines the default lookup rules to resolve
+ container lookups before consulting the container for registered
+ items:
+
+* templates are looked up on `Ember.TEMPLATES`
+* other names are looked up on the application after converting
+ the name. For example, `controller:post` looks up
+ `App.PostController` by default.
+* there are some nuances (see examples below)
+
+ ### How Resolving Works
+
+ The container calls this object's `resolve` method with the
+ `fullName` argument.
+
+ It first parses the fullName into an object using `parseName`.
+
+ Then it checks for the presence of a type-specific instance
+ method of the form `resolve[Type]` and calls it if it exists.
+ For example if it was resolving 'template:post', it would call
+ the `resolveTemplate` method.
+
+ Its last resort is to call the `resolveOther` method.
+
+ The methods of this object are designed to be easy to override
+ in a subclass. For example, you could enhance how a template
+ is resolved like so:
+
+ ```javascript
+ App = Ember.Application.create({
+ Resolver: Ember.DefaultResolver.extend({
+ resolveTemplate: function(parsedName) {
+ var resolvedTemplate = this._super(parsedName);
+ if (resolvedTemplate) { return resolvedTemplate; }
+ return Ember.TEMPLATES['not_found'];
+ }
+ })
+ });
+ ```
+
+ Some examples of how names are resolved:
+
+ ```
+ 'template:post' //=> Ember.TEMPLATES['post']
+ 'template:posts/byline' //=> Ember.TEMPLATES['posts/byline']
+ 'template:posts.byline' //=> Ember.TEMPLATES['posts/byline']
+ 'template:blogPost' //=> Ember.TEMPLATES['blogPost']
+ // OR
+ // Ember.TEMPLATES['blog_post']
+ 'controller:post' //=> App.PostController
+ 'controller:posts.index' //=> App.PostsIndexController
+ 'controller:blog/post' //=> Blog.PostController
+ 'controller:basic' //=> Ember.Controller
+ 'route:post' //=> App.PostRoute
+ 'route:posts.index' //=> App.PostsIndexRoute
+ 'route:blog/post' //=> Blog.PostRoute
+ 'route:basic' //=> Ember.Route
+ 'view:post' //=> App.PostView
+ 'view:posts.index' //=> App.PostsIndexView
+ 'view:blog/post' //=> Blog.PostView
+ 'view:basic' //=> Ember.View
+ 'foo:post' //=> App.PostFoo
+ 'model:post' //=> App.Post
+ ```

+ An instance of `Ember.Application` is the starting point for every Ember
+ application. It helps to instantiate, initialize and coordinate the many
+ objects that make up your app.
+
+ Each Ember app has one and only one `Ember.Application` object. In fact, the
+ very first thing you should do in your application is create the instance:
+
+ ```javascript
+ window.App = Ember.Application.create();
+ ```
+
+ Typically, the application object is the only global variable. All other
+ classes in your app should be properties on the `Ember.Application` instance,
+ which highlights its first role: a global namespace.
+
+ For example, if you define a view class, it might look like this:
+
+ ```javascript
+ App.MyView = Ember.View.extend();
+ ```
+
+ By default, calling `Ember.Application.create()` will automatically initialize
+ your application by calling the `Ember.Application.initialize()` method. If
+ you need to delay initialization, you can call your app's `deferReadiness()`
+ method. When you are ready for your app to be initialized, call its
+ `advanceReadiness()` method.
+
+ You can define a `ready` method on the `Ember.Application` instance, which
+ will be run by Ember when the application is initialized.
+
+ Because `Ember.Application` inherits from `Ember.Namespace`, any classes
+ you create will have useful string representations when calling `toString()`.
+ See the `Ember.Namespace` documentation for more information.
+
+ While you can think of your `Ember.Application` as a container that holds the
+ other classes in your application, there are several other responsibilities
+ going on under-the-hood that you may want to understand.
+
+ ### Event Delegation
+
+ Ember uses a technique called _event delegation_. This allows the framework
+ to set up a global, shared event listener instead of requiring each view to
+ do it manually. For example, instead of each view registering its own
+ `mousedown` listener on its associated element, Ember sets up a `mousedown`
+ listener on the `body`.
+
+ If a `mousedown` event occurs, Ember will look at the target of the event and
+ start walking up the DOM node tree, finding corresponding views and invoking
+ their `mouseDown` method as it goes.
+
+ `Ember.Application` has a number of default events that it listens for, as
+ well as a mapping from lowercase events to camel-cased view method names. For
+ example, the `keypress` event causes the `keyPress` method on the view to be
+ called, the `dblclick` event causes `doubleClick` to be called, and so on.
+
+ If there is a bubbling browser event that Ember does not listen for by
+ default, you can specify custom events and their corresponding view method
+ names by setting the application's `customEvents` property:
+
+ ```javascript
+ App = Ember.Application.create({
+ customEvents: {
+ // add support for the paste event
+ paste: "paste"
+ }
+ });
+ ```
+
+ By default, the application sets up these event listeners on the document
+ body. However, in cases where you are embedding an Ember application inside
+ an existing page, you may want it to set up the listeners on an element
+ inside the body.
+
+ For example, if only events inside a DOM element with the ID of `ember-app`
+ should be delegated, set your application's `rootElement` property:
+
+ ```javascript
+ window.App = Ember.Application.create({
+ rootElement: '#ember-app'
+ });
+ ```
+
+ The `rootElement` can be either a DOM element or a jQuery-compatible selector
+ string. Note that *views appended to the DOM outside the root element will
+ not receive events.* If you specify a custom root element, make sure you only
+ append views inside it!
+
+ To learn more about the advantages of event delegation and the Ember view
+ layer, and a list of the event listeners that are setup by default, visit the
+ [Ember View Layer guide](http://emberjs.com/guides/understanding-ember/the-view-layer/#toc_event-delegation).
+
+ ### Initializers
+
+ Libraries on top of Ember can register additional initializers, like so:
+
+ ```javascript
+ Ember.Application.initializer({
+ name: "store",
+
+ initialize: function(container, application) {
+ container.register('store:main', application.Store);
+ }
+ });
+ ```
+
+ ### Routing
+
+ In addition to creating your application's router, `Ember.Application` is
+ also responsible for telling the router when to start routing. Transitions
+ between routes can be logged with the `LOG_TRANSITIONS` flag, and more
+ detailed intra-transition logging can be logged with
+ the `LOG_TRANSITIONS_INTERNAL` flag:
+
+ ```javascript
+ window.App = Ember.Application.create({
+ LOG_TRANSITIONS: true, // basic logging of successful transitions
+ LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps
+ });
+ ```
+
+ By default, the router will begin trying to translate the current URL into
+ application state once the browser emits the `DOMContentReady` event. If you
+ need to defer routing, you can call the application's `deferReadiness()`
+ method. Once routing can begin, call the `advanceReadiness()` method.
+
+ If there is any setup required before routing begins, you can implement a
+ `ready()` method on your app that will be invoked immediately before routing
+ begins.
+ ```
