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

javascript 复制代码

"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

javascript 复制代码

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。
