【问题描述】：
我需要制作一个与此页面中的非常相似的 jQuery“轮播”：http://m.henrys.com/
有很多“carousel” jQuery 插件，但是如何将 carousel next/prev 页面动作绑定到“swipe”手机/平板手势？

【问题描述】：
您要么为此使用 JQM 插件（我见过一些可用的），要么添加自己的触摸事件管理并手动调用所选插件的 next/prev。
例如，
$(document).swiperight(function(){
jqPlugin.goPrev();
});
$(document).swipeleft(function(){
jqPlugin.goNext();
});
有关 JQM 活动的更多详细信息，请参阅他们的documentation

-
但是...你能引用一些你看到的好的jqm轮播插件吗？ :)
-
这是我刚刚找到的一个-JQM carousel widget，演示看起来不错，但我个人从未使用过...
-
也许在演示中，但在 jscript 世界中它都是动态的 ;-)
-
WooThemes 的那个不错，支持触控：flexslider.woothemes.com/basic-carousel.html
这是他们的 jQuery carousel 插件的代码
