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M F ` Q 6 n g q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-aj y O { g { ppp V_ N C (ue

  • 同样的先构造DOM结构
<view class="custom-audio">
<image v-if="X c I DaudioSrc !== undef. d wined && audioSrc !== null && audioSrc !== ''" @click=h F z y E ; F 2"playOrStopAudio" :src="https://www.php.cn/uni-app/audioImg" class="audio-btn" />
<text v-else @click="tips" class="audio-btn">无音源<p 8 e / S f/text>
<text>{{ fmtSecond(currentTR 1 c R yim* B 9 E z d + : Ne) }}/{{ 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P c 8 ] Q的坑这里就直接上代码了)
