麻烦大家帮我看看啊呢，

问题是：

点击“下一首”后还要手动点“播放当前”才可以真的播放，而我分明在“下一首”绑定的函数里调用了play函数。

也没报错，音源地址确定也没有问题。

首先是界面：

附上代码：

//js

audioNext: function () { 

  this.audioCtx.pause()

  console.log(“audionext pause”)

    index=index+1

    if (index>2) {index=0}   

      this.setData({

      index:index

})

    this.audioCtx.play()

    console.log(“to play audioNext”)

  },

audioPlay: function () {

    this.audioCtx.play()

    console.log(“audio play begin”)

    console.log(this.audioCtx);

    console.log(“audio play end”)

  },

audioPause: function () {

     console.log(“audio pause begin”)

    this.audioCtx.pause()

    console.log(“audio pause end”)

  },

audioFirst: function () {

      this.audioCtx.pause()

        console.log(“audionext pause”)

    index=0  

    this.setData({

   index:index

})

    this.audioCtx.play()

  },

onReady: function () {

this.audioCtx = wx.createAudioContext(‘myAudio’)

         console.log(this.audioCtx)

  },

//wxml
