vue项目如何使用jQuery

第一步：安装 jquery 的依赖包

cnpm install jquery --save

第二步：在程序中配置jquery，只在这一个配置文件（webpack.base.conf.js）中配置就行。

整体的配置文件如下：

'use strict'
const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueloaderconfig = require('./vue-loader.conf')


function resolve (dir) {
return path.join(__dirname, '..', dir)
}


//第一处，引入 webpack
var webpack = require('webpack')


module.exports = {
context: path.resolve(__dirname, '../'),
entry: {
app: './src/main.js'
},
output: {
path: config.build.assetsroot,
filename: '[name].js',
publicpath: process.env.node_env === 'production'
? config.build.assetspublicpath
: config.dev.assetspublicpath
},
resolve: {
extensions: ['.js', '.vue', '.json'],
alias: {
'vue$': 'vue/dist/vue.esm.js',
'@': resolve('src'),
'jqery': 'jquery'
}
},
module: {
rules: [
{
test: /\.vue$/,
loader: 'vue-loader',
options: vueloaderconfig
},
{
test: /\.js$/,
loader: 'babel-loader',
include: [resolve('src'), resolve('test'), resolve('node_modules/webpack-dev-server/client')]
},
{
test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetspath('img/[name].[hash:7].[ext]')
}
},
{
test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/,
loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetspath('media/[name].[hash:7].[ext]')
}
},
{
test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,
loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetspath('fonts/[name].[hash:7].[ext]')
}
}
]
},
node: {
// prevent webpack from injecting useless setimmediate polyfill because vue
// source contains it (although only uses it if it's native).
setimmediate: false,
// prevent webpack from injecting mocks to node native modules
// that does not make sense for the client
dgram: 'empty',
fs: 'empty',
net: 'empty',
tls: 'empty',
child_process: 'empty'
}


// 第二处配置 jquery 插件
plugins: [
new webpack.provideplugin({
$: "jqery"
jquery: "jquery"
})
]
}

第三步：使用
