Device Specific Javascript, preferably JQuery

I have a pretty Jquery-heavy site in the rollout. However, since it uses fullscreen backgrounds ... which are pretty useless on mobile de开发者_C百科vices I would love to deactivate the Jquery plugin on mobile devices...

I tried to research this problem but did not came up with a simple solutions...

Media queries won't really do... since there's too much reliance upon Javascript... media Queries are CSS-only right (I am more a designer than a programmer.... )

u will have to detect wether its a mobile device using tools like WURFL and then deactivate it.
