Detailed explanation of the method of referencing js files in vue

This time I will bring you a detailed explanation of the vuequotejs file method. What are the precautions for vue to reference js files. The following is a practical case, let's take a look.

1. vue-cli webpack globally introduces jquery

(1) First npm install jquery --save (--save means Install the module into the project directory and write dependencies in the dependencies node of the package file.)

(2) Add

  var webpack = require("webpack")

(3) to webpack.base.conf.js (3) module.exports is added at the end

plugins: [
 new webpack.optimize.CommonsChunkPlugin('common.js'),
 new webpack.ProvidePlugin({
 jQuery: "jquery",
 $: "jquery"
 })
]

(4) and it is ok if it is introduced in main.js (this step is not necessary for testing)

import $ from 'jquery'

(5) Then npm run dev can use $ directly in the page.

2. The method of vue component referencing external js

The project structure is as follows:

content component code:

<template>
 <p>
   <input ref=&#39;test&#39; id="test">
   <button @click=&#39;diyfun&#39;>Click</button>
 </p>
</template>
<script>
import {myfun} from '../js/test.js' //注意路径
export default {
 data () {
  return {
   testvalue: ''
  }
 },
 methods:{
   diyfun:function(){
     myfun();
   }
 }
}
</script>

test.js code:

function myfun() {
console.log('Success')
}
export { //很关键
 myfun
}

uses es6 syntax.

3. Single vue page refers to the internal js method

(1) First npm install jquery --save (--save means Install the module into the project directory and write dependencies in the dependencies node of the package file.)

(2) Import $ in the vue page that needs to be referenced, and then use it

There is a yellow warning in this picture. If you change console.log($) to this:

export default{
  mounted: function(){
    console.log($)
  }
}
