Question

Which javascript framework is most compatible with mobile phones and desktop both?

javascript disabled user of desktop are very low but mobile phone users are high and i heard not all javascript functions work in mobile phones.

Answer 1

there is no js-framework that works on all mobile phones:

• if your target is iphone, jqtouch does offer nice iphone-specific stuff on top of jquery
• if you want to reach iphone and android (and possibly some other high-end handsets) you could try xui, which is a jquery-like lightweight js-framework (by one of the phonegap-guys)
• if your goal is to work on as many phones as possible, you might want to consider building the core of you site/app in standard html and progressively enhancing it with javascript for those

hope this helps,
