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.
