vue + element ui实现播放器功能的实例代码

作者:大海patterson

这篇文章主要介绍了vue + element ui实现播放器功能,本文通过实例代码给大家介绍的非常详细,对大家的学习或工作具有一定的参考借鉴价值,需要的朋友可以参考下

没有效果图的展示都是空口无凭

在这里插入图片描述

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

<div class="right di main-wrap" v-loading="audio.waiting">
   <!-- 此处的ref属性,可以很方便的在vue组件中通过 this.$refs.audio获取该dom元素 -->
   <audio ref="audio" class="dn"

   @play="onPlay"
   @error="onError"
   @waiting="onWaiting"
   @pause="onPause"
   @timeupdate="onTimeupdate"
   @loadedmetadata="onLoadedmetadata"
   ></audio>

   <div class="w-full">
     <div class="flex items-center w-10/12 mx-auto">
       <!-- 当前时间 -->
       <el-tag type="info">{{ audio.currentTime | formatSecond}}</el-tag>

       <!-- 滚动条 -->
       <el-slider v-show="!controlList.noProcess" v-model="sliderTime" :format-tooltip="formatProcessToolTip" @change="changeCurrentTime" class="slider_time"></el-slider>
       <!-- 总时长 -->
       <el-tag type="info">{{ audio.maxTime | formatSecond }}</el-tag>
     </div>
     <div class="mt-3 flex items-center w-1/2 mx-auto justify-around">
       <!-- 播放/暂停 -->
       <el-button type="text" @click="startPlayOrPause">{{audio.playing | transPlayPause}}</el-button>
       <!-- 快进 -->
       <el-button v-show="!controlList.noSpeed" type="text" @click="changeSpeed">{{audio.speed | transSpeed}}</el-button>
       <!-- 静音 -->
       <el-button v-show="!controlList.noMuted" type="text" @click="startMutedOrNot">{{audio.muted | transMutedOrNot}}</el-button>
       <!-- 音量 -->
       <div class="flex items-center">
         <span class="mr-2 text-sm">音量</span>
         <el-slider v-show="!controlList.noVolume" v-model="volume" :format-tooltip="formatVolumeToolTip" @change="changeVolume" class="slider_voice"></el-slider>

</script>

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>
