JSLINT is a global function. It takes two parameters.
|
|
|
30 |
|
|
|
31 |
var myResult = JSLINT(source, option);
|
|
|
32 |
|
|
|
33 |
The first parameter is either a string or an array of strings. If it is a
|
|
|
34 |
string, it will be split on '\n' or '\r'. If it is an array of strings, it
|
|
|
35 |
is assumed that each string represents one line. The source can be a
|
|
|
36 |
JavaScript text, or HTML text, or a Konfabulator text.
|
|
|
37 |
|
|
|
38 |
The second parameter is an optional object of options which control the
|
|
|
39 |
operation of JSLINT. Most of the options are booleans: They are all are
|
|
|
40 |
optional and have a default value of false.
|
|
|
41 |
|
|
|
42 |
If it checks out, JSLINT returns true. Otherwise, it returns false.
|
|
|
43 |
|
|
|
44 |
If false, you can inspect JSLINT.errors to find out the problems.
|
|
|
45 |
JSLINT.errors is an array of objects containing these members:
|
|
|
46 |
|
|
|
47 |
{
|
|
|
48 |
line : The line (relative to 0) at which the lint was found
|
|
|
49 |
character : The character (relative to 0) at which the lint was found
|
|
|
50 |
reason : The problem
|
|
|
51 |
evidence : The text line in which the problem occurred
|
|
|
52 |
raw : The raw message before the details were inserted
|
|
|
53 |
a : The first detail
|
|
|
54 |
b : The second detail
|
|
|
55 |
c : The third detail
|
|
|
56 |
d : The fourth detail
|
|
|
57 |
}
|
|
|
58 |
|
|
|
59 |
If a fatal error was found, a null will be the last element of the
|
|
|
60 |
JSLINT.errors array.
|
|
|
61 |
|
|
|
62 |
You can request a Function Report, which shows all of the functions
|
|
|
63 |
and the parameters and vars that they use. This can be used to find
|
|
|
64 |
implied global variables and other problems. The report is in HTML and
|
|
|
65 |
can be inserted in an HTML <body>.
|
|
|
66 |
|
|
|
67 |
var myReport = JSLINT.report(limited);
|
|
|
68 |
|
|
|
69 |
If limited is true, then the report will be limited to only errors.
|
|
|
70 |
|
|
|
71 |
You can request a data structure which contains JSLint's results.
|
|
|
72 |
|
|
|
73 |
var myData = JSLINT.data();
|
|
|
74 |
|
|
|
75 |
It returns a structure with this form:
