旧版

<!-- audio.wxml -->
<audio poster="{{poster}}" name="{{name}}" author="{{author}}" src="{{src}}" id="myAudio" controls loop></audio>

<button type="primary" bindtap="audioPlay">播放</button>
<button type="primary" bindtap="audioPause">暂停</button>
<button type="primary" bindtap="audio14">设置当前播放时间为14秒</button>
<button type="primary" bindtap="audioStart">回到开头</button>

// audio.js
Page({
  onReady: function (e) {
    // 使用 wx.createAudioContext 获取 audio 上下文 context
    this.audioCtx = wx.createAudioContext('myAudio')
  },
  data: {
    poster: 'http://y.gtimg.cn/music/photo_new/T002R300x300M000003rsKF44GyaSk.jpg?max_age=2592000',

  },
  audioPlay: function () {
    this.audioCtx.play()
  },
  audioPause: function () {

  },
  audio14: function () {
    this.audioCtx.seek(14)
  },
  audioStart: function () {

  }
})

新版：wx.createInnerAudioContext的使用

const myaudio = wx.createInnerAudioContext();
