JSHint globals选项在.jshintrc中不起作用

Question

I'm using Brackets 1.2 and the extension brackets-jshint . Here is my .jshintrc in my project root:

{
    'bitwise': true,
    'boss': true,
    'camelcase': true,
    'curly': true,
    'devel': true,
    'eqeqeq': true,
    'eqnull': true,
    'expr': true,
    'forin': true,
    'iterator': false,
    'latedef': true,
    'multistr': false,
    'nocomma': true,
    'noarg': true,
    'noempty': true,
    'nonbsp': true,
    'nonew': true,
    'quotmark': 'single',
    'undef': true,
    'unused': true,
    'globals': {
        '$': true,
        'document': true,
        'jQuery': true,
        'window': true
    }
}

The globals option is not working and the white list of global variables are still being warned by JSHint.

I also tried these:

globals: true
jquery: true
devel: true 

But no success, $ , jquery , window , document and alert are still warned.

You must replace single quotes with double in .jshintrc : ) This answer is to short, so I'm going to add a little explanations …

Just open Debug » Developers tools try to validate some JavaScript file – you can see in debug console

JSHint: error parsing /project/path/.jshintrc. Details: SyntaxError: Unexpected token '

As method responsible for reading .jshintrc looks like:

try {
    config = JSON.parse(removeComments(content));
} catch (e) {
    console.error("JSHint: error parsing " + file.fullPath + ". Details: " + e);
    result.reject(e);
    return;
}

JSON.parse implements http://www.ietf.org/rfc/rfc4627.txt - according to ECMAScript Specification and there is no place for ' .

From rfc 4627 only valid structure to describe JSON is

 string = quotation-mark *char quotation-mark char = unescaped / escape ( %x22 / ; " quotation mark U+0022 %x5C / ; \\ reverse solidus U+005C %x2F / ; / solidus U+002F %x62 / ; b backspace U+0008 %x66 / ; f form feed U+000C %x6E / ; n line feed U+000A %x72 / ; r carriage return U+000D %x74 / ; t tab U+0009 %x75 4HEXDIG ) ; uXXXX U+XXXX escape = %x5C ; \\ quotation-mark = %x22 ; "

Please make sure you have disabled JSLint, the linter that comes with Brackets by default. You can do so by adding this snippet to your brackets.json (open via Debug > Show Preferences File ):

"language": {
    "javascript": {
        "linting.prefer": "JSHint",
        "linting.usePreferredOnly": true
    }
}
