这个要通过javaScript+css+html来实现。
通过setTimeout或setInteral来实现吧。

可以讨论 但没有现成的代码...
我觉得通过setTimeout隔段时间刷新，来实现一个切换...不过没有jquery切换那么好看...

在移动web开发中，由于手机界面较小，为了能展示更多的图片经常使用轮播图并且还需要考虑到手机流量的问题，通过请教他人以及百度，个人感觉swipe.js比较好用。
它是一个纯javascript工具，不需要跟其它js库一起导入，同时兼容jQuery和zepto，压缩版的大小只有6kb很适合移动端的开发，它的git地址：https://github.com/thebird/swipe
在git上对其的使用方式介绍的相当清楚，关键代码如下
