vue + element ui实现播放器功能的实例代码

没有效果图的展示都是空口无凭

1.基于audio并结合elementUI 的进度条实现
2.实现了播放器基本的功能，播放/暂停、快进、静音、调节声音大小、下载等功能

html代码，关键部分已加注释

CSS代码用的是SCSS

<style scoped lang=\"scss\">
  .right{
     width: 100%;
     padding: 10px 15px;
     display: inline-block;
     .slider {
       display: inline-block;
       position: relative;
       top: 14px;
       margin-left: 15px;
     }
     .slider_time{
       width: 550px;
       margin: 0 10px;
     }
     .slider_voice{
       width: 80px;
     }
     .download {
       color: #409EFF;
       margin-left: 15px;
     }

     .dn{
       display: none;
     }
   }

</style>
