uni.createInnerAudioContext 通过 watch 监听 src ,在微信小程序中不会触发

[monkeying-boy]

问题描述 在 globalData 中通过 uni.createInnerAudioContext 创建音频播放器设置 src 地址，并且在组件通过 watch 监听，在 h5 可以触发 watch 事件，但是在微信小程序环境下不会触发 watch 事件。

复现步骤

1. 在 globalData 中配置

// App.vue
globalData:{
    audio: uni.createInnerAudioContext(),
  }

2. 在组件中监听

<template>
  <view>
    <view>{{player.src}}</view>
    <button @click="handler">修改地址</button>
  </view>
</template>

<script>
export default {
  data(){
    return{
      player:getApp().globalData.audio
    }
  },
  watch:{
    'player.src'(n){
      console.log(n,'修改')
    }
  },
  methods:{
    handler(){
      this.player.src= 'https://bjetxgzv.cdn.bspapp.com/VKCEYUGU-hello-uniapp/2cc220e0-c27a-11ea-9dfb-6da8e309e0d8.mp3'
    }
  }
}
</script>

3. h5 运行结果

4. 微信小程序运行结果

没有任何输出但是实际上已经去获取音频文件了。

预期结果 如果可以希望小程序环境能够和 h5 保持一致，均可触发 watch
