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 <body>. + + 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, + line: NUMBER, + last: NUMBER, + param: [ + STRING + ], + closure: [ + STRING + ], + var: [ + STRING + ], + exception: [ + STRING + ], +
