效果图
在这里插入图片描述
首先引入wavesurfer.js
在这里插入图片描述
其次 封装 wavesurfer.js`

<template>
  <div class="waveformOuter">
    <div id="waveform" ref="waveform" />
    <div class="play" @click="playMusic">
      <svg-icon v-if="!isPlaying" icon-class="play" class="icon myplay" />
      <svg-icon v-else icon-class="stop" class="icon mystop" />
      <p>{{ time }}</p>
    </div>
      <!-- <p>{{ url }}</p> -->
  </div>
</template>
<script>
import WaveSurfer from '@/assets/js/wavesurfer'
export default {
  props: ['url', 'toStopMusic', 'loadWave'],
  data() {
    return {
      isPlaying: false,
      time: '00:00',
      wavesurfer: null,
    }
  },
  watch: {
    'loadWave': function() {
      this.loadMusic()
    },
    'url': function() {
      // return this.wavesurfer.getCurrentTime()
      this.loadMusic(true)
      console.log('url---------------------------------------')
    },
    'toStopMusic': function() {
      console.log('toStopMusic---------------------------------------')
      if (this.wavesurfer) {
        this.wavesurfer.pause()
      }
    }
  },
  mounted() {
    this.$nextTick(() => {
      if (this.loadWave) {
        console.log('haha')
        this.loadMusic()
      }
    })
  },
  methods: {
    itemClick(node) {
      console.log(node.model.id)
    },
    buZero(num) {
      return num > 9 ? num : '0' + num
    },
    loadMusic(bool) {
      console.log('this.WaveSurfer--------------------------------------', WaveSurfer)
      if (this.wavesurfer) {
        if (bool) {
          this.time = '00:00'
          this.wavesurfer.load(this.url)
        }
      } else {
        this.wavesurfer = WaveSurfer.create({
          container: this.$refs.waveform,
          waveColor: 'violet',
          progressColor: 'purple'
        })
        this.wavesurfer.load(this.url)
        this.wavesurfer.on('ready', () => {
          // this.wavesurfer.play()
        })
        this.wavesurfer.on('audioprocess', (e) => {
          const times = Math.floor(e)
          this.time = this.buZero(Math.floor(times / 60)) + ':' + this.buZero(times % 60)
        })
        this.wavesurfer.on('finish', () => {
          this.isPlaying = false
        })
      }
    },
    stopMusic(){
      if (this.wavesurfer) {
          this.wavesurfer.stop();
        }
    },
    playMusic() {
      console.log("开始")
      console.log(this.wavesurfer)
      console.log("点击开始播放按钮",this.url)
      if (this.wavesurfer) {
        if (this.wavesurfer.isPlaying()) {
          this.isPlaying = false
        debugger
          this.wavesurfer.pause()
        } else {
          this.isPlaying = true
          this.wavesurfer.play()
        }
      }
    }
  }
}
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
.myplay{
  position: absolute;
  top: 50%;
  font-size: 17px;
  margin: -10px 0 0 -9px;
  left: 50%;
}
.mystop{
  position: absolute;
  top: 50%;
  margin: -15px 0 0 -18px;
  left: 50%;
  font-size: 25px;
}
#waveform{
  width: calc(100% - 150px);
  height:128px;
  float: left;
  margin-right: 22px;
  background: black;
}
.play{
  position: relative;
  width: 128px;
  height:128px;
  border-radius:3px;
  background-color:#EBEEF5;
  float: left;
  text-align: center;
}
.play p{
  margin-top: 85px;
  color:  #3683FA;
}

.waveformOuter{
  margin-bottom: 20px;
  overflow: hidden;
}
</style>

再然后 在需要的组件中引入

<div class="luyin" v-if="this.isYinyin">
                <!-- {{this.isYinyin}} -->
     <my-wave-sufer ref="handleDialogClose" :url="luyinUrl" :load-wave="showDialog" :to-stop-music="!showDialog" />
</div>

 
 		  isYinyin: false,//是否加载录音组件
	      showDialog: true,  //是否初始化录音组件
	      luyinUrl: "", //录音url    
	      数据库录音格式  123.wav
