在vue項目中，為了使用ztree樹插件，我引入了jquery，然后在vue文件中使用jquery的語法：
$.fn.zTree.init($('#treeDemo'), this.setting, this.zNodes)

控制臺報了一下警告：

我的eslint.rc文件是這樣的：

// https://eslint.org/docs/user-guide/configuring

module.exports = {
  root: true,
  parserOptions: {
    parser: 'babel-eslint'
  },
  env: {
    browser: true,
  },
  extends: [
    // https://github.com/vuejs/eslint-plugin-vue#priority-a-essential-error-prevention
    // consider switching to `plugin:vue/strongly-recommended` or `plugin:vue/recommended` for stricter rules.
    'plugin:vue/essential',
    // https://github.com/standard/standard/blob/master/docs/RULES-en.md
    'standard'
  ],
  // required to lint *.vue files
  plugins: [
    'vue'
  ],
  // add your custom rules here
  rules: {
      // allow async-await
      'generator-star-spacing': 'off',
      // allow debugger during development
      'no-debugger': process.env.NODE_ENV === 'production' ? 'error' : 'off',
      'eol-last': 0,
      'space-before-function-paren': 0,
      'indent': 'off',
      "no-undef": 2
  }
}

問題：我想關(guān)閉no-undef規(guī)則的校驗，該怎么設(shè)置？查看了eslint的官網(wǎng)沒有找到地方。
