Thanks for the reply Mike. I suppose ultimately I'd need to dig into the JavaScript (hopefully it's not compressed) to figure out the PHP routing. I believe re-writing my application with the framework would be quite extensive and just not feasible at this particular point in time, although I should consider it in the future if my application remains problematic and this is a solid solution. The concept of calling back-end code via anchor tags though is something I've never seen. - sf On 1/7/08, mike <mike503@xxxxxxxxx> wrote: > > It's probably using IUI (the iPhone UI CSS/JS that Joe Hewitt created, > now being maintained at http://code.google.com/p/iui/) which allows > you to request the page to be loaded via AJAX based on how you setup > the link. > > <a href="foo.php">this will load via AJAX</a> > > <a href="foo.php" target="_self">this will load like a normal page > link</a> > > This is how I *believe* it works, I just implemented IUI partially on > a site at work a few days ago and the final thing for me to work out > the kinks is whether or not to load certain pages using the AJAX > method (and show the cute little "loading" circle thing) or reload the > entire page. > > Remember it's all just Javascript trickery with CSS that works great > on Safari browsers (and works almost identical actually now in > Firefox...) > > It's very easy to implement, I had some initial confusion too how it > routes the requests but I think I figured it out there ^^ > > > > On 1/7/08, Steve Finkelstein <sf@xxxxxxxxxxxxx> wrote: > > Hi folks, > > > > Probably the most impressive application I've run into for the iPhone > has to > > be Facebook's implementation.
