微信小程序多音频播放进度条问题

真的脑子疼，小程序的音频组件居然没有进度控制的功能，网上的方法又很少，逻辑通了就好写了。

1.所有音频播放、停止按钮使用状态切换控制
2.当点击某个音频播放时，首先将所有音频的状态置为停止状态，然后将当前音频置为播放状态
3.滚动条插件配合音频控件一起使用
4.播放状态时滚动条的长度随音频进度变化而变化，时间也要显示
5.拖动滚动条时，音频的当前时间随滚动条变化而变化

1.wxml

<text class="left_text">{{item.currentprocess}}</text>
        <slider class="slider_middle" bindchange="changeslide" bindtouchstart="start" bindtouchend="end" max="{{item.totalprocessnum}}" min="0" value="{{item.currentprocessnum}}" disabled="{{item.canslider}}" block-size  ="18" data-index="{{index}}"></slider>
        <text class="right_text">{{item.totalprocess}}</text>
        <image class="audio_btn" wx:if="{{!item.showaudio}}" src="../assets/play.png" data-src="{{item.src}}" bindtap="playaudio" data-index = "{{index}}"></image>
        <image class="audio_btn" wx:else src="../assets/pause.png" bindtap="pauseaudio" data-index = "{{index}}"></image>
