- JSHINT is a global function. It takes two parameters.
-
- var myResult = JSHINT(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 a JSON text.
-
- The second parameter is an optional object of options which control the
- operation of JSHINT. Most of the options are booleans: They are all
- optional and have a default value of false. One of the options, predef,
- can be an array of names, which will be used to declare global variables,
- or an object whose keys are used as global names, with a boolean value
- that determines if they are assignable.
-
- If it checks out, JSHINT returns true. Otherwise, it returns false.
-
- If false, you can inspect JSHINT.errors to find out the problems.
- JSHINT.errors is an array of objects containing these members:
-
- {
- line : The line (relative to 1) at which the lint was found
- character : The character (relative to 1) 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
- JSHINT.errors array.
-
- You can request a data structure which contains JSHint's results.
-
- var myData = JSHINT.data();
-
- It returns a structure with this form:
-
- {
- errors: [
- {
- line: NUMBER,
- character: NUMBER,
- reason: STRING,
- evidence: STRING
- }
- ],
- functions: [
- name: STRING,
