JSLINT is a global function. It takes two parameters.
|
|
|
|
var myResult = JSLINT(source, option);
|
|
|
|
The first parameter is either a string or an array of strings. If it is a
|
|
string, it will be split on '\n' or '\r'. If it is an array of strings, it
|
|
is assumed that each string represents one line. The source can be a
|
|
JavaScript text, or HTML text, or a Konfabulator text.
|
|
|
|
The second parameter is an optional object of options which control the
|
|
operation of JSLINT. Most of the options are booleans: They are all are
|
|
optional and have a default value of false.
|
|
|
|
If it checks out, JSLINT returns true. Otherwise, it returns false.
|
|
|
|
If false, you can inspect JSLINT.errors to find out the problems.
|
|
JSLINT.errors is an array of objects containing these members:
|
|
|
|
{
|
|
line : The line (relative to 0) at which the lint was found
|
|
character : The character (relative to 0) at which the lint was found
|
|
reason : The problem
|
|
evidence : The text line in which the problem occurred
|
|
raw : The raw message before the details were inserted
|
|
a : The first detail
|
|
b : The second detail
|
|
c : The third detail
|
|
d : The fourth detail
|
|
}
|
|
|
|
If a fatal error was found, a null will be the last element of the
|
|
JSLINT.errors array.
|
|
|
|
You can request a Function Report, which shows all of the functions
|
|
and the parameters and vars that they use. This can be used to find
|
|
implied global variables and other problems. The report is in HTML and
|
|
can be inserted in an HTML <body>.
|
|
|
|
var myReport = JSLINT.report(limited);
|
|
|
|
If limited is true, then the report will be limited to only errors.
|
|
|
|
You can request a data structure which contains JSLint's results.
|
|
|
|
var myData = JSLINT.data();
|
|
|
|
It returns a structure with this form:
|
|
|
|

|
|

|
|
