JSHINT is a global function. It takes two parameters.
|
| 35 |
|
| 36 |
var myResult = JSHINT(source, option);
|
| 37 |
|
| 38 |
The first parameter is either a string or an array of strings. If it is a
|
| 39 |
string, it will be split on '\n' or '\r'. If it is an array of strings, it
|
| 40 |
is assumed that each string represents one line. The source can be a
|
| 41 |
JavaScript text or a JSON text.
|
| 42 |
|
| 43 |
The second parameter is an optional object of options which control the
|
| 44 |
operation of JSHINT. Most of the options are booleans: They are all
|
| 45 |
optional and have a default value of false. One of the options, predef,
|
| 46 |
can be an array of names, which will be used to declare global variables,
|
| 47 |
or an object whose keys are used as global names, with a boolean value
|
| 48 |
that determines if they are assignable.
|
| 49 |
|
| 50 |
If it checks out, JSHINT returns true. Otherwise, it returns false.
|
| 51 |
|
| 52 |
If false, you can inspect JSHINT.errors to find out the problems.
|
| 53 |
JSHINT.errors is an array of objects containing these members:
|
| 54 |
|
| 55 |
{
|
| 56 |
line : The line (relative to 1) at which the lint was found
|
| 57 |
character : The character (relative to 1) at which the lint was found
|
| 58 |
reason : The problem
|
| 59 |
evidence : The text line in which the problem occurred
|
| 60 |
raw : The raw message before the details were inserted
|
| 61 |
a : The first detail
|
| 62 |
b : The second detail
|
| 63 |
c : The third detail
|
| 64 |
d : The fourth detail
|
| 65 |
}
|
| 66 |
|
| 67 |
If a fatal error was found, a null will be the last element of the
|
| 68 |
JSHINT.errors array.
|
| 69 |
|
| 70 |
You can request a data structure which contains JSHint's results.
|
| 71 |
|
| 72 |
var myData = JSHINT.data();
|
| 73 |
|
| 74 |
It returns a structure with this form:
