材料/屬性/方法
讓我們開始吧
uni-app Vue同樣的先構(gòu)造DOM結(jié)構(gòu)
<view class="custom-audio">
<image v-if="audioSrc !== undefined && audioSrc !== null && audioSrc !== ''" @click="playOrStopAudio" :src="audioImg" class="audio-btn" />
<text v-else @click="tips" class="audio-btn">無音源</text>
<text>{{ fmtSecond(currentTime) }}/{{ fmtSecond(duration) }}</text></view>復(fù)制代碼
定義接受的組件
props: { audioSrc: { type: String, default: ''
},
},復(fù)制代碼
定義CustomAudio組件的初始化相關(guān)的操作，并給innerAudioContext的回調(diào)添加一些行為（之前Taro那篇我們踩過的坑這里就直接上代碼了）
import { formatSecondToHHmmss, afterAudioPlay, beforeAudioRecordOrPlay } from '../../lib/Utils'const iconPaused = '../../static/images/icon_paused.png'const iconPlaying = '../../static/images/icon_playing.png'const iconStop = '../../static/images/icon_stop.png'const iconLoading = '../../static/images/icon_loading.gif'// ...data() { return { audioCtx: null, // 音頻上下文
duration: 0, // 音頻總時長
currentTime: 0, // 音頻當(dāng)前播放的時長
audioImg: iconLoading, // 默認狀態(tài)為加載中
}
},watch: { audioSrc: {
handler(newSrc, oldSrc) { console.log('watch', newSrc, oldSrc) this.audioImg = iconLoading this.currentTime = 0
this.duration = 0
if (this.audioCtx === undefined) { this.audioCtx = uni.createInnerAudioContext() this.onTimeUpdate = this.audioCtx.onTimeUpdate this.bindAuidoCallback(this.audioCtx)
} else { this.audioCtx.src = newSrc
} if (this.audioCtx.play) { this.audioCtx.stop()
getApp().globalData.audioPlaying = false
}

同樣的scss文件
<style lang="scss" scoped>.custom-audio { border-radius: 8vw; border: #CCC 1px solid; background: #F3F6FC; color: #333; display: flex; flex-flow: row nowrap; align-items: center; justify-content: space-between; padding: 2vw; font-size: 14px;
.audio-btn { width: 10vw; height: 10vw; white-space: nowrap; display: flex; align-items: center; justify-content: center;
}
}
</style>復(fù)制代碼
