wxml代码如下：

<!--当前为停止状态  --><view style="width:250rpx;height:250rpx;left:250rpx;top:12rpx;position:relative;" wx:if="{{isplay==false}}" bindtap='play'>  <image style="width:100%;height:100%;border-radius:50%;" src='http://y.gtimg.cn/music/photo_new/T002R300x300M000003rsKF44GyaSk.jpg?max_age=2592000' />  <image src='../image/play.png' style="width:100rpx;height:100rpx;position:absolute;left:75rpx;top:75rpx;"></image></view>

<!--当前为播放状态  --><view style="width:250rpx;height:250rpx;left:250rpx;top:12rpx;position:relative;" wx:if="{{isplay==true}}" bindtap='stop'>  <image style="width:100%;height:100%;border-radius:50%;" src='http://y.gtimg.cn/music/photo_new/T002R300x300M000003rsKF44GyaSk.jpg?max_age=2592000' />  <image src='../image/stop.png' style="width:100rpx;height:100rpx;position:absolute;left:75rpx;top:75rpx;"></image></view><slider style="width:500rpx;margin-left:125rpx;"></slider>

js的代码如下：

const myaudio = wx.createInnerAudioContext();

Page({

  data: {

    isplay: false,//是否播放

     },

onShow: function ()

{    myaudio.src = "http://ws.stream.qqmusic.qq.com/M500001VfvsJ21xFqb.mp3?guid=ffffffff82def4af4b12b3cd9337d5e7&uin=346897220&vkey=6292F51E1E384E06DCBDC9AB7C49FD713D632D313AC4858BACB8DDD29067D3C601481D36E62053BF8DFEAF74C0A5CCFADD6471160CAF3E6A&fromtag=46"   },  //播放

  play: function ()

   {     myaudio.play();  

    console.log(myaudio.duration);   

    this.setData({ isplay: true }); 

    },  // 停止 

    stop: function ()

    {    myaudio.pause();   

    this.setData({ isplay: false });

     }   })
