Question

The following JS:

(function() {
  "use strict";

  $("#target").click(function(){
    console.log("clicked");
  });

}());

继承:

test.js: line 5, col 3,  $  is not defined.

当使用JHint0.5.5时。任何想法?

Answer 1

如果你使用比较近期的JHint版本,通常更可取的做法是在你的项目根基中建立一个jshintrc文档,并将这一简略列入:

{
    "globals": {
        "$": false
    }
}

这向人权联盟宣布,美元是一个全球性的变数,而错误表明,它不应凌驾于一切之上。

最初的Jshintrc案(例如,与2012年原始问题一样)没有得到支持。如果你不能或不想使用jshintrc文档,你可以在文件顶上添加:

/*globals $:false */

在上,还有一段简短的“jquery” j。 JSHint Options page .

Answer 2

你还可以在你看来增加两条。

  "globals": {
    "$": false,
    "jQuery": false
  }

这说明有两种全球变量。

这一办法界定了Jan Query Java成文图书馆所揭露的全球人物。

Answer 4

Here is a happy little list to put in your .jshintrc
I will add to this list at time passes.

{
  // other settings...
  // ENVIRONMENTS
  // "browser": true, // Is in most configs by default
  "node": true,
  // others (e.g. yui, mootools, rhino, worker, etc.)
  "globals": {
    "$":false,
    "jquery":false,
    "angular":false
    // other explicit global names to exclude
  },
}

Answer 5

如果您重新使用英特尔利J编辑,如WebStorm、PyCharm、Ruby Mine或IntelliJ IDEA:

In the Environments section of File/Settings/JavaScript/Code Quality Tools/JSHint, click on the jQuery checkbox.

Answer 6

我建议使用Module patterns来解决这个问题。它保留了你的代码“包含”并提高了业绩(基于Paul Irish s 10 。

我倾向于撰写我的模块模式,如:

(function (window) {
    // Handle dependencies
    var angular = window.angular,
        $ = window.$,
        document = window.document;

    // Your application s code
}(window))

您可以领取这些其他业绩福利(详情见 http://briancray.com/posts/javascript-module-pattern”rel=“nofollow”>here ):

When minifying code, the passed in window object declaration gets minified as well. e.g. window.alert() become m.alert().
Code inside the self-executing anonymous function only uses 1 instance of the window object.
You cut to the chase when calling in a window property or method, preventing expensive traversal of the scope chain e.g. window.alert() (faster) versus alert() (slower) performance.
Local scope of functions through "namespacing" and containment (globals are evil). If you need to break up this code into separate scripts, you can make a submodule for each of those scripts, and have them imported into one main module.

Answer 7

如果你重新使用英特尔利J编辑,主编

Preferences/Settings
- Javascript
  - Code Quality Tools
    - JSHint
      - Predefined (at bottom), click Set

你可以做任何事情,例如<代码>console:false,并将在清单(jshintrc)中加上全球。

Answer 8

在使用 :

Click "CONFIGURE" (top of the middle column on the page)
Enable "jQuery" (under the "ASSUME" section at the bottom)

Answer 9

您也许想做以下工作:

const $ = window.$

避免出现倾斜错误。
