I'm trying to server HTML Javascript and CSS content from an iPhone application's local resources, and I'm having trouble handling onOrientationChange events and including external Javascript.
I seem to be able to link in CSS properly but not javascript. I'm trying to use the following example of handling onOrientationChange (How to build an iPhone website) but I'm serving the webpage from my app's NSBundle mainBundle.
I tried attaching a javascript function to body.onorientationchange and to window.onorientationchange but neither work when served from UIWebView locally (or remotely), but it works if I'm using the iPhone Safari.

<p>This doesn't work yet, but there is a chance apple will enable it at some point, so I've put it in anyway. You would be holding your phone upside down if it did work.</p>
