vue

上效果：

1.安装wavesurfer

npm install wavesurfer.js

2.在页面导入

import WaveSurfer from 'wavesurfer.js'

注:我没有使用时间轴，所以没有引入，如果需要再引入

import Timeline from 'wavesurfer.js/dist/plugin/wavesurfer.timeline.js'

3.上源码

<template>
  <el-row>
    <el-card class="card" :body-style="{ padding: '10px' }">
      <div id="waveform" ref="waveform">
      </div>
    </el-card>
  </el-row>
  <div>
        <el-button type="primary" @click="playMusic">
          <i class="el-icon-video-play"></i>
          播放 /
          <i class="el-icon-video-pausee"></i>
          暂停
        </el-button>
      </div>
</template>
<script>
import WaveSurfer from "wavesurfer.js";
// import Timeline from "wavesurfer.js/dist/plugin/wavesurfer.timeline.js";
export default {
  name: "Details",
  data() {
    return {
      wavesurfer: null,
    };
  },
  mounted() {
    this.$nextTick(() => {
      this.wavesurfer = WaveSurfer.create({
        container: this.$refs.waveform,
        // waveColor: '#409EFF',
        barWidth: 1,
        cursorColor: "black",
        progressColor: "blue",
        backend: "MediaElement",
        // mediaControls: false,
        audioRate: "1",
        //使用时间轴插件
      });
      // 特别提醒：此处需要使用require(相对路径)，否则会报错
      this.wavesurfer.load(require("../mp3/living.mp3"));
    });
  },
  methods: {
    playMusic() {
      //"播放/暂停"按钮的单击触发事件，暂停的话单击则播放，正在播放的话单击则暂停播放
      this.wavesurfer.playPause.bind(this.wavesurfer)();
    },
  },
};
