### 应用场景 ###

vue采用数据驱动，不对dom进行操作。 有的时候为了控制屏幕的宽高度等，需要引入jquery来进行处理。如何配置呢？

### package.json 配置 ###

"dependencies": {
         
      "axios": "^0.19.0", 
      "core-js": "^3.4.4", 
      "echarts": "^4.8.0", 
      "element-ui": "^2.13.0", 
      "jquery": "^3.4.1", 
      "ol": "^6.1.1", 
      "qs": "^6.9.4", 
      "screenfull": "^5.0.2", 
      "vue": "^2.6.10", 
      "vue-i18n": "^8.15.3", 
      "vue-router": "^3.1.3", 
      "vuex": "^3.1.2" 
    },

### vue.config.js配置 ###

const CopyWebpackPlugin = require('copy-webpack-plugin') 
    const webpack = require('webpack') 
    const path = require('path') 
    const debug = process.env.NODE_ENV !== 'production' 
     
    module.exports = {
         
     
        configureWebpack: {
         
     
            resolve: {
         
                alias: {
         
                    'vue$': 'vue/dist/vue.esm.js', 
                    '@': path.resolve('src') 
                } 
            }, 
            plugins: [ 
                new webpack.ProvidePlugin({
         
                    $: "jquery", 
                    jQuery: "jquery", 
                    "windows.jQuery": "jquery" 
                }), 
            ], 
     
        }, 
     
        pluginOptions: {
         
            'style-resources-loader': {
         
                preProcessor: 'less', 
                patterns: [path.resolve(__dirname, "src/css/index.less")] 
            } 
        } 
    }

### main.js配置 ###

> import $ from ‘jquery’

配置完后就可以在项目中使用$l了。
