vue-cli項目中單文件組件引入bootstrap.js異常的解決方案

0.修改webpack.base.conf.js

 1 var webpack = require ("webpack") //add
 2 
 3 //...
 4 
 5 module.exports = {
 6   resolve: {
 7     extensions: ['.js', '.vue', '.json'],
 8     alias: {
 9       'vue$': 'vue/dist/vue.esm.js',
10       '@': resolve('src'),
11       'jquery' : 'jquery' //add
12     }
13   },
14   // add
15   plugins : [
16     new webpack.ProvidePlugin ({
17       // 將jquery及其別名註冊到全局
18       $ : "jquery" ,
19       jQuery : "jquery",
20       'window.jQuery' : 'jquery' ,
21       // 將Popper及其別名註冊到全局
22       Popper : ['popper.js' , 'default']
23     })
24   ] 
25 //...
26 }

1.修改bootstrap源碼

 1 (function (global, factory) {
 2     typeof exports === 'object' && typeof module !== 'undefined' ? factory(exports, require('jquery'), require('popper.js')) :
 3     typeof define === 'function' && define.amd ? define(['exports', 'jquery', 'popper.js'], factory) :
 4     (factory((global.bootstrap = {}),global.jQuery,global.Popper));
 5 }(
 6   window , // 此參數本來爲this,改成window
 7   (function (exports,$,Popper) { 'use strict';
 8 
 9 $ = $ && $.hasOwnProperty('default') ? $['default'] : $;
10 Popper = Popper && Popper.hasOwnProperty('default') ? Popper['default'] : Popper;
11 //...
12 }))) ;

2.在單文件組件(.vue)或main.js中引入bootstrap.js

import '/the/path/of/bootstrap.js'
