vue实现自定义音乐播放器

项目中遇到了，让实现一个音乐播放器的功能。修改其样式要求自定义，切需要有，进度条，时间，开关，应用于H5需要兼容ios与android。简单看一下如图播放器

完成代码

audioCom.vue

<template>
  <div class="myaudio">
    <audio
      @timeupdate="updateProgress"
      controls
      ref="audioRef"
      style="display: none"
      @canplay="getDuration"
    >
      <source :src="fileurl" type="audio/mpeg" />
      您的浏览器不支持音频播放
    </audio>
    <div class="audioPanel">
      <div class="playBtn" @click="playAudio">
        <img
          v-show="audioStatus == 0"
          src="@/assets/images/main/icon_play.png"
          alt=""
        />
        <img
          v-show="audioStatus == 1"
          src="@/assets/images/main/icon_stop.png"
          alt=""
        />
      </div>
      <div class="slidList">

为了更好地处理IOS duration兼容问题

我们在mounted中添加了自动触发touchstart方法，去进入页面触发一次，这里goole新版本不允许立即播放，会抛出异常，但无关紧要。

  mounted() {
    if (this.fileurl&&!this.isToPla) {
      this.$nextTick(() => {
        document.addEventListener(
          "touchstart",
          () => {
            if(this.isToPla){
                return
            }
            this.$refs.audioRef.play();
            this.$refs.audioRef.pause();
          },
          false
        );
      });
    }
  },

isToPla：目的是触发一次后停止继续触发该touch函数
