实现效果如下,包含后退,播放暂停,前进,指定播放,音量,播放倍速修改等功能
1、常用的方法如下:
playPause() //播放时暂停,播放时暂停
skip(number) //从当前位置跳数秒(使用负值向后移动)
stop() //重放
setVolume(newVolume) //将播放音量设置为新值[0…1](0 =静音,1 =最大)
play([start[, end]]) //从当前位置开始播放。可选start且end以秒为单位可用于设置要播放的音频范围
2、使用代码如下
<template> <div class="mixin-components-container"> <el-row> <el-card class="box-card" style="text-align:left"> <div id="waveform" ref="waveform"> <!-- Here be the waveform --> </div> <div id="wave-timeline" ref="wave-timeline"> <!--时间轴 --> </div> <div> <el-button type="primary" @click="rew">后退</el-button> <el-button type="primary" @click="plays"> <i class="el-icon-video-play"></i> 播放 / <i class="el-icon-video-pausee"></i> 暂停 </el-button> <el-button type="primary" @click="speek">前进</el-button> <el-button type="primary" @click="replay">重放</el-button> <el-tooltip class="item" effect="dark" content="指定播放" placement="bottom"> <el-popover placement="top" width="200" trigger="click"> <el-input v-model="appointTime" placeholder="请输入内容" class="input-with-select"> <el-button slot="append" @click="appointPlay">播放</el-button> </el-input> <el-button slot="reference" circle> 指定播放 </el-button> </el-popover> </el-tooltip> <span style="border: 2px solid #2f4f4f;margin-left: 8px;margin-right: 4px" /> <el-tooltip class="item" effect="dark" content="音量" placement="bottom"> <el-popover placement="top-start" trigger="click" style="min-width: 38px;margin-left: 10px"> <div class="block" style="width: 42px"> <el-slider v-model="value" vertical height="100px" @change="setVolume" /> </div> <el-button slot="reference" circle> 音量 </el-button> </el-popover> </el-tooltip> <el-tooltip class="item" effect="dark" content="播放倍速" placement="bottom"> <el-popover placement="top" width="220" trigger="click" style="margin-left: 10px"> <el-input-number v-model="ds" width="180" :precision="2" :step="0.1" :min="0.5" :max="2" @change="DoubleSpeed" /> <el-button slot="reference" round> {{ ds +' X' }} </el-button> </el-popover> </el-tooltip> </div> </el-card> </el-row> </div> </template> <script> import WaveSurfer from 'wavesurfer.js' import CursorPlugin from 'wavesurfer.js/dist/plugin/wavesurfer.cursor.js' import Timeline from 'wavesurfer.js/dist/plugin/wavesurfer.timeline.js' export default { name: "Details", // components: { MyWaveSurfer }, data() { return { wavesurfer: null, // 指定播放功能的播放时间点 appointTime: 1, // 播放倍速 ds: 1.00, // 设置音量 value: 0, }; }, mounted() { this.$nextTick(() => { console.log(WaveSurfer) this.wavesurfer = WaveSurfer.create({ // 应该在其中绘制波形的CSS选择器或HTML元素。这是唯一必需的参数。 container: this.$refs.waveform, // 光标的填充颜色,指示播放头的位置。 cursorColor:'red', // 更改波形容器的背景颜色。 backgroundColor:'gray', // 光标后的波形填充颜色。 waveColor: 'violet', // 光标后面的波形部分的填充色。当progressColor和waveColor相同时,完全不渲染进度波 progressColor: 'purple', backend: 'MediaElement', // 音频播放时间轴 mediaControls: false, // 播放音频的速度 audioRate: '1', // 插件:此教程配置了光标插件和时间轴插件 plugins: [ // 光标插件 CursorPlugin.create({ showTime: true, opacity: 1, customShowTimeStyle: { 'background-color': '#000', color: '#fff', padding: '2px', 'font-size': '10px' } }), // 时间轴插件 Timeline.create({ container: '#wave-timeline' }), ] }); this.wavesurfer.on('error', function(e) { console.warn(e); }); this.wavesurfer.load(require('./peaks/sample.mp3')); // this.value = this.wavesurfer.getVolume() * 100 }) }, methods: { // 播放时暂停,播放时暂停 plays() { this.wavesurfer.playPause() }, // 后退, rew() { this.wavesurfer.skip(-3) }, // 前进, speek() { this.wavesurfer.skip(3) }, // 重放 replay() { this.wavesurfer.stop() }, // 设置音量: setVolume(val) { this.wavesurfer.setVolume(val / 100) }, // 指定播放 appointPlay() { this.wavesurfer.play([this.appointTime,]) }, } } </script> <style scoped> .mixin-components-container { background-color: #f0f2f5; padding: 30px; min-height: calc(100vh - 84px); } </style>
