（IOS可自动播放）使用bxslider做了一个切换图片跟随播放MP3的功能

页面代码我直接copy过来的。有需要的请自己精简一下。bxslider轮播api文档：http://www.uedsc.com/jquery-bxslider-api.html

注意：这个网页在IOS系统上面不能播放，IOS有防止浪费用户流量的限制，禁止自动播放。还好微信出了个js脚本。

<script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>
    <script type="text/javascript">
        document.addEventListener("WeixinJSBridgeReady", function () {
            document.getElementById('myvideo').play();
        }, false);
    </script>

加上这个代码就可以播放了。参考文章：https://www.cnblogs.com/xiongdahei/p/7144700.html
