voice: function (event){
    var that = this;
    clearInterval(that.data.times)
    var arr = ['../../image/voice_001.png', '../../image/voice_011.png','../../image/voice_01.png']
     
    const backgroundAudioManager = wx.getBackgroundAudioManager()
    backgroundAudioManager.stop()
    backgroundAudioManager.onStop(function(){
      clearInterval(that.data.times)
      that.setData({
        bigPic: arr[2]
      })
      console.log("播放停止");
    })
    backgroundAudioManager.src = event.target.dataset.url // 设置了 src 之后会自动播放
    backgroundAudioManager.onPlay(function(){
      console.log("开始播放")
      util.play(arr, "bigPic", function (i, time) {
 
        that.setData({
          bigPic: arr[i],
          times: time
        })
      })
    })
    backgroundAudioManager.onEnded(function(){
      clearInterval(that.data.times)
      that.setData({
        bigPic: arr[2]
      })  
      console.log("播放完成");
    })
  }

现在是需要做一个点击把之前的播放停止然后重新播放的功能，现在点击之后停止了，但是重新播放无法生效，想知道有什么办法可以让重新播放生效

play:function(){
  var that = this
  const backgroundAudioManager = wx.getBackgroundAudioManager()
  backgroundAudioManager.title = '此时此刻'
  if(that.data.fg == 1){
    backgroundAudioManager.src = 'https://cos-bi-ppt-1252899312.cos.ap-shanghai.myqcloud.com/word/ci/1.mp3'
  }else{
    backgroundAudioManager.src = 'https://cos-bi-ppt-1252899312.cos.ap-shanghai.myqcloud.com/word/ci/2.mp3'
  }
   
  backgroundAudioManager.onStop(function(){
    console.log("停止")
  })
  backgroundAudioManager.onPlay(function(){
    console.log("开始")
    if (that.data.fg == 1){
      that.setData({
        fg: 2
      })
    }else{
      that.setData({
        fg: 1
      })
    }
     
  })
  backgroundAudioManager.onEnded(function(){
    if (that.data.fg == 1) {
      that.setData({
        fg: 2
      })
    } else {
      that.setData({
        fg: 1
      })
    }
  })
   
}

现在是多加了一个音频路径，在播放其中一个时，如果再次点击，就播放另一个音频。这样才能实现打断之前的播放并且__立即__重新播放的功能
