  29.     JSLINT is a global function. It takes two parameters.
    30. 

  30. 

  31.         var myResult = JSLINT(source, option);
    32. 

  32. 

  33.     The first parameter is either a string or an array of strings. If it is a
    34. 

  34.     string, it will be split on '\n' or '\r'. If it is an array of strings, it
    35. 

  35.     is assumed that each string represents one line. The source can be a
    36. 

  36.     JavaScript text, or HTML text, or a Konfabulator text.
    37. 

  37. 

  38.     The second parameter is an optional object of options which control the
    39. 

  39.     operation of JSLINT. Most of the options are booleans: They are all are
    40. 

  40.     optional and have a default value of false.
    41. 

  41. 

  42.     If it checks out, JSLINT returns true. Otherwise, it returns false.
    43. 

  43. 

  44.     If false, you can inspect JSLINT.errors to find out the problems.
    45. 

  45.     JSLINT.errors is an array of objects containing these members:
    46. 

  46. 

  47.     {
    48. 

  48.         line      : The line (relative to 0) at which the lint was found
    49. 

  49.         character : The character (relative to 0) at which the lint was found
    50. 

  50.         reason    : The problem
    51. 

  51.         evidence  : The text line in which the problem occurred
    52. 

  52.         raw       : The raw message before the details were inserted
    53. 

  53.         a         : The first detail
    54. 

  54.         b         : The second detail
    55. 

  55.         c         : The third detail
    56. 

  56.         d         : The fourth detail
    57. 

  57.     }
    58. 

  58. 

  59.     If a fatal error was found, a null will be the last element of the
    60. 

  60.     JSLINT.errors array.
    61. 

  61. 

  62.     You can request a Function Report, which shows all of the functions
    63.
