未定义ESLint dollar($). (没有undef) [英] ESLint dollar($) is not defined. (no-undef)

问题描述

$("#ID").hide();

我将ESLint添加到我的项目中.

i add ESLint to my project .

一切正常，除了符号$.

我收到错误消息:[eslint] '$' is not defined. (no-undef)

我的.eslintrc.json(注意:它已将其他规则设置为禁止使用jquery函数如果有一个等效的javascript):

my .eslintrc.json (note: it has additional rules set to disallow jquery functions when there's an equivalent javascript one):

{
"env": {
    "browser": true,
    "commonjs": true,
    "es6": true

    "jquery/no-wrap": 2,
    "dollar-sign/dollar-sign": [
        2,
        "ignoreProperties"
    ]
}

您可以看到我添加了两个插件: eslint-plugin-dollar-签名和eslint-plugin-jquery.

you can see that I have added two plugins: eslint-plugin-dollar-sign and eslint-plugin-jquery.

为什么此规则不起作用?

why does not work this rule ?

"dollar-sign/dollar-sign": [ 2, "ignoreProperties" ]

"dollar-sign/dollar-sign": [ 2, "ignoreProperties" ]

推荐答案

您丢失了

"env": {
  "browser": true,
  "commonjs": true,
  "es6": true,
  "jquery": true
},

如果未启用jquery环境，则不会将

$声明为全局变量.因此，您将得到一个no-undef错误，表示您正在使用尚未声明的变量.

$ is not declared as a global without jquery environment enabled. Because of that, you are getting a no-undef error, saying that you are using variable that haven't been declared.
