vue自定义js图片碎片轮播图切换效果的实现代码

定义一个banner.js文件，代码如下

}
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>
//css样式
<style>

}

/*

} */
.banner-btn span:hover{
 background-color: rgba(0,0,0,0.6);
}
.banner-btn span + span{
 float: right;
}
.banner-number{

 left: 0;
 top: 0;
 border-radius: 3px;
 display: block;
 height: 100％;
 width: 0;
}
</style>
// js的引用
this.obj = {
     container : '#banner1',//选择容器 必选
