vue如何导入外部js文件（自测可用）

一、ES5

var  JSElement=document.createElement("script");
JSElement.setAttribute("type","text/javascript");
JSElement.setAttribute("src","https://g.alicdn.com/dingding/dingtalk-jsapi/2.7.13/dingtalk.open.js");
document.body.appendChild(JSElement);

二、ES6

import { dd } from 'https://g.alicdn.com/dingding/dingtalk-jsapi/2.7.13/dingtalk.open.js'
