使Web应用程序与掌上电脑兼容

I'm developing a web app, with a full ajax ui using html, css and jquery as the js framework.

Along with css changes to make those pages compatible with handheld devices, there are little operational differences in js. i.e user does not select dates in handheld whilst they can on pc.I'm developing a web app, with a full ajax ui u
