vue + element ui實(shí)現(xiàn)播放器功能的實(shí)例代碼

 更新時(shí)間：2021年04月14日 11:20:29   作者：大海patterson  
這篇文章主要介紹了vue + element ui實(shí)現(xiàn)播放器功能，本文通過(guò)實(shí)例代碼給大家介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值，需要的朋友可以參考下

沒(méi)有效果圖的展示都是空口無(wú)憑

在這里插入圖片描述

1.基于audio并結(jié)合elementUI 的進(jìn)度條實(shí)現(xiàn)
2.實(shí)現(xiàn)了播放器基本的功能，播放/暫停、快進(jìn)、靜音、調(diào)節(jié)聲音大小、下載等功能

html代碼，關(guān)鍵部分已加注釋

CSS代碼用的是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>
