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 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 - JSHINT.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 . - - var myReport = JSHINT.report(limited); - - If limited is true, then the report will be limited to only errors. - - 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, -
