微信小程序实现播放音频

本文实例为大家分享了微信小程序实现播放音频的具体代码，供大家参考，具体内容如下

wxml：

<!-- 语音 -->
<view wx:if="{{content.mp3.length > 0 }}">
  <view class='audio' bindtap='musicStart'>
    <view class='audio_btn'>
      <image src='/img/btn_play3.png' class='image-full' wx:if="{{playStatus}}"></image>
      <!-- 未播放-->
      <image src='/img/btn_stop@2x.png' class='image-full' wx:else catchtap='canel_handover'></image>
      <!-- 播放中-->
    </view>
    <view class='audio_pro'>
      <slider class="drag" step="10" value="{{curTimeVal}}" max="{{duration}}" backgroundColor="#efefef" activeColor="#90BED5" />
    </view>
    <text class='audio_text'>{{formatedPlayTime}}</text>
  </view>
</view>

wxss：

/* 传语音 */
.audio{
  display:flex;
  position:relative;
  height:140rpx;
  line-height:140rpx;
  background:#f7f7f7;
  width:690rpx;
  margin:0 auto;
}
.audio_img{
  position: absolute;
  top:-15rpx;
  right:-15rpx;
  width:30rpx;
  height:30rpx;
}
.audio_btn{
  width:88rpx;
  height:88rpx;
  margin-top:28rpx;
   margin-left:42rpx
}
.audio_pro{
  margin-top:36rpx;
  margin-left:20rpx;
  width:410rpx;
