vue + element ui实现播放器功能的实例代码

时间:2021-05-26

没有效果图的展示都是空口无凭

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" :src="url" :preload="audio.preload" @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> </div> <!-- 下载 --> <a :href="url" rel="external nofollow" v-show="!controlList.noDownload" target="_blank" class="download text-sm" download>下载</a> </div> </div> </div>

js代码

<script> // 将整数转换成 时:分:秒的格式 function realFormatSecond(second) { var secondType = typeof second if (secondType === 'number' || secondType === 'string') { second = parseInt(second) var hours = Math.floor(second / 3600) second = second - hours * 3600 var mimute = Math.floor(second / 60) second = second - mimute * 60 return hours + ':' + ('0' + mimute).slice(-2) + ':' + ('0' + second).slice(-2) } else { return '0:00:00' } } export default { name: 'voicetotext', props: { theSpeeds: { type: Array, default () { return [1, 1.5, 2] } }, theControlList: { type: String, default: '' } }, data(){ return{ url: 'https://wdd.js.org/element-audio/static/falling-star.mp3', audio: { currentTime: 0, maxTime: 0, playing: false, muted: false, speed: 1, waiting: true, preload: 'auto' }, sliderTime: 0, volume: 100, speeds: this.theSpeeds, controlList: { // 不显示下载 noDownload: false, // 不显示静音 noMuted: false, // 不显示音量条 noVolume: false, // 不显示进度条 noProcess: false, // 只能播放一个 onlyOnePlaying: false, // 不要快进按钮 noSpeed: false } } }, methods:{ setControlList () { let controlList = this.theControlList.split(' ') controlList.forEach((item) => { if(this.controlList[item] !== undefined){ this.controlList[item] = true } }) }, changeSpeed() { let index = this.speeds.indexOf(this.audio.speed) + 1 this.audio.speed = this.speeds[index % this.speeds.length] this.$refs.audio.playbackRate = this.audio.speed }, startMutedOrNot() { this.$refs.audio.muted = !this.$refs.audio.muted this.audio.muted = this.$refs.audio.muted }, // 音量条toolTip formatVolumeToolTip(index) { return '音量条: ' + index }, // 进度条toolTip formatProcessToolTip(index = 0) { index = parseInt(this.audio.maxTime / 100 * index) return '进度条: ' + realFormatSecond(index) }, // 音量改变 changeVolume(index = 0) { this.$refs.audio.volume = index / 100 this.volume = index }, // 播放跳转 changeCurrentTime(index) { this.pausePlay() this.$refs.audio.currentTime = parseInt(index / 100 * this.audio.maxTime) }, startPlayOrPause() { return this.audio.playing ? this.pausePlay() : this.startPlay() }, // 开始播放 startPlay() { this.$refs.audio.play() }, // 暂停 pausePlay() { this.$refs.audio.pause() }, // 当音频暂停 onPause () { this.audio.playing = false }, // 当发生错误, 就出现loading状态 onError () { this.audio.waiting = true }, // 当音频开始等待 onWaiting (res) { console.log(res) }, // 当音频开始播放 onPlay (res) { console.log(res) this.audio.playing = true this.audio.loading = false if(!this.controlList.onlyOnePlaying){ return } let target = res.target let audios = document.getElementsByTagName('audio'); [...audios].forEach((item) => { if(item !== target){ item.pause() } }) }, // 当timeupdate事件大概每秒一次,用来更新音频流的当前播放时间 onTimeupdate(res) { // console.log('timeupdate') // console.log(res) this.audio.currentTime = res.target.currentTime this.sliderTime = parseInt(this.audio.currentTime / this.audio.maxTime * 100) }, // 当加载语音流元数据完成后,会触发该事件的回调函数 // 语音元数据主要是语音的长度之类的数据 onLoadedmetadata(res) { this.audio.waiting = false this.audio.maxTime = parseInt(res.target.duration) } }, filters: { formatSecond(second = 0) { return realFormatSecond(second) }, transPlayPause(value) { return value ? '暂停' : '播放' }, transMutedOrNot(value) { return value ? '放音' : '静音' }, transSpeed(value) { return '快进: x' + value } }, created() { this.setControlList() } }</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>
