javascript framework for ipad safari browser and desktop web browser

i am in the process of selecting a technology for building an application which would be targeted on the ipad safari browser or the normal desktop web browser. I am leaned towards YUI since it has mobile support and custom libraries. i am not going for DOJO since it doesnt support addition of custom features on their libraries and not GWT because it is a single page application which causes 开发者_StackOverflow社区the flow between pages very slow. any ideas are welcome

I would go with jQuery mobile.

Sencha Touch uses all the latest doodads in webkit, and if you're only looking at Apple OS's you would be insane not to look at it as a framework - but then again, I do work for Sencha. In addition to the aforementioned JQuery Mobile, you should also take a look at jqTouch if you want to stick with a markup based approach. (BTW, there's nothing inherently slow about an SPA. A well programmed SPA should be lower latency than a page-driven one.)
