微信小程序wx.createInnerAudioContext使用方法

1.创建audio对象

js开头：

const myaudio = wx.createInnerAudioContext({});

2.设置资源路径，onShow或者onLoad内设置

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

3.页面

<view class='audioContainer'>
  <view>录音</view>
  <!--当前为停止状态  -->
  <view class='audioImg' wx:if="{{isplay==false}}" bindtap='play'>
    <image style="width:100%;height:100%;border-radius:50%;" src='/pages/image/play.png' />
  </view>
  <!--当前为播放状态  -->
  <view class='audioImg'  wx:if="{{isplay==true}}" bindtap='stop'>
    <image style="width:100%;height:100%;border-radius:50%;" src='/pages/image/pause.png' />
  </view>
</view>
<view style='width:50%'>
<button bindtap='review' type='primary'>重新播放</button>
</view>

4.为页面注册方法，播放暂停重播

  //播放
  play: function () {
      
    myaudio.play();
    console.log(myaudio.duration);
    this.setData({ isplay: true });
  },
  // 停止
  stop: function () {
    myaudio.pause();
    this.setData({ isplay: false });
  },
  /**
   * 重播
   */
  review:function(){
   myaudio.stop();

    myaudio.play()
    this.setData({ isplay: true });
  }

5.监听事件，在onLoad或onshow中设置

  onLoad:function(){
    myaudio.onPause(function(){
      console.log('mmp')
      wx.showToast({
        title: 'heheda',
      })
    })
    
  },

6.这个组件应该可以实现背景音乐~~~
