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:
