触摸屏是现在所有智能手机的标配，还包括各种平板设备，而且很多桌面也慢慢在开始支持触摸操作。要开发支持触摸屏设备的 Web 应用，我们需要借助浏览器的触摸事件来实线。
下图是各种触摸事件说明：

jGestures简介
jGestures插件允许你如同原生的jQuery事件一样监听以下事件：'pinch'(缩放手势), 'rotate'(旋转手势), 'swipe'(滑动手势), 'tap'(轻触) 以及 'orientationchange'(改变设备方向)。当然，部分事件在PC浏览器上可以通过转换实现。比如 "tapone" 事件可以被 "clicking"事件触发,鼠标手势也可以产生"swipe"事件。
使用示例
- $('#swipe').bind('swipeone',eventHandler);
