- 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.
