module.exports.FragmentBanner = FragmentBanner;

在需要的组件里面引入改js

import {FragmentBanner} from '../../../static/js/banner.js'

使用方式如下

// html代码
<header class="js_header mod-header">
 <div class="banner" id="banner1" style="margin: 50px auto;margin-bottom:0px">
 <div class="banner-view"></div>
 <div class="banner-btn"></div>
 <div class="banner-number"></div>
 <div class="banner-progres"></div>
 </div>
 </header>
