原由
同样的是因为小程序官方不维护audio组件了
音频组件的要求与限制
1、点击播放或者暂停
2、显示播放进度及总时长
3、通过图标变化显示当前音频所处状态（暂停/播放/加载中）
4、页面音频更新时刷新组件状态
5、全局有且只有一个音频处于播放状态
6、离开页面之后要自动停止播放并销毁音频实例
材料/属性/方法
让我们开始吧
uni-app Vue
- 同样的先构造
DOM结构
<view>
<image></image>
<text>无音源</text>
<text>{{ fmtSecond(currentTime) }}/{{ fmtSecond(duration) }}</text></view>复制代码
- 定义接受的组件
props: { audioSrc: { type: String, default: ''
},
},复制代码
- 定义
CustomAudio组件的初始化相关的操作，并给innerAudioContext的回调添加一些行为（之前Taro那篇我们踩过的坑这里就直接上代码了）
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, // 音频上下文
duration: 0, // 音频总时长
currentTime: 0, // 音频当前播放的时长
audioImg: iconLoading, // 默认状态为加载中
}
},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
}
}
}
},
mounted() { this.audioCtx = uni.createInnerAudioContext() this.audioCtx.src = this.audioSrc this.audioCtx.startTime = 0
this.bindAuidoCallback(this.audioCtx)
},methods: {
bindAuidoCallback(ctx) {
ctx.onTimeUpdate((e) => { this.onTimeUpdate(e)
})
ctx.onCanplay((e) => { this.onCanplay(e)
})
ctx.onWaiting((e) => { this.onWaiting(e)
})
ctx.onPlay((e) => { this.onPlay(e)
})
ctx.onPause((e) => { this.onPause(e)
})
ctx.onEnded((e) => { this.onEnded(e)
})
ctx.onError((e) => { this.onError(e)
})
},
tips(){
uni.showToast({ title: '无效音源,请先录音', icon: 'none'
})
},
playOrStopAudio() { if (this.audioCtx === null) { this.audioCtx = uni.createInnerAudioContext() this.audioCtx.src = this.audioSrc this.bindAuidoCallback(this.audioCtx)
} if (this.audioCtx.paused) { if (beforeAudioRecordOrPlay('play')) { this.audioCtx.play() this.audioImg = iconPlaying
}
} else { this.audioCtx.pause()
afterAudioPlay() this.audioImg = iconPaused
}
},
onTimeUpdate(e) { console.log('onTimeUpdate', this.audioCtx.duration, this.audioCtx.currentTime) if (this.audioCtx.currentTime > 0 && this.audioCtx.currentTime 0 && this.audioCtx.duration <h3 data-id="heading-4">同样的<code>scss</code>文件</h3><pre class="brush:php;toolbar:false;"><style>.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;
