微信小程序 audio 组件实例详解

音频播放已经封装的很好！只需配合属性设置即可！ （method和data配合使用）

主要属性：

wxml

<audio
 action="{{action}}"
 src='http://sc1.111ttt.com/2016/1/09/26/202261732256.mp3'
 poster= 'http://avatar.csdn.net/E/3/9/1_u014360817.jpg'
 controls="true"
 name="钢琴曲"
 author="不详"/>

<button type="primary" bindtap="audioPlay">播放</button>
<button type="primary" bindtap="audioPause">暂停</button>
<!--正常速度-->
<button type="primary" bindtap="audioPlaybackRateNormal">调为1倍速</button>
<!--慢放-->
<button type="primary" bindtap="audioPlaybackRateSlowDown">调为0.5倍速</button>

js

Page({
 data:{
 // text:"这是一个页面"
 action: {
  method: ''
 }
 },

 audioPlay:function() {
 this.setData({
  action: {
  method: 'play'
  }
