this.

backgroundAudioManager = wx.getBackgroundAudioManager()

this.backgroundAudioManager.title = _this.data.PlayJs_import_Data.introduce;

this.backgroundAudioManager.src = src;

this.backgroundAudioManager.onCanplay(()=>{         

console.log(“视频缓冲完毕，可以播放啦~”);               

   wx.hideLoading()           

  })
