如何在vue-cli webpack中全局引入jquery
1.首先执行:npm install jQuery --save-dev,在package.json
里加入jQuery。
2.修改build下的webpack.base.conf.js
方法一:
首先加入:
const webpack = require("webpack")
然后在module.exports 对象中加入:
plugins: [ new webpack.optimize.CommonsChunkPlugin('common.js'), new webpack.ProvidePlugin({ jQuery: "jquery", $: "jquery" }) ]
方法二:
先加入:
const webpack = require("webpack")
然后:
resolve: { extensions: ['.js', '.vue', '.json'], alias: { 'vue$': 'vue/dist/vue.esm.js', '@': resolve('src'), 'jquery': 'jquery' } },
最后:
plugins: [ new webpack.ProvidePlugin({ jQuery: "jquery", $: "jquery" }) ]
3.在app.vue中调用jquery
mounted: function() { console.log($); console.log($('#ss')[0].innerHTML); },
打印结果:
