Depends on your application. What would it do if it wasn't implemented with AJAX?
This isn't a magical feature. It's a feature that allows you to support the back button 1) if it makes sense to you and 2) if you can figure out a way to make it safe for the user. For example, you click the delete button. The snippet is replaced by "Item deleted". You click back button, now you're back to the item you deleted. If you go back again, maybe you go back to the list of items you were working with and from there you can go delete others. So it's just a navigation tool to support existing web idioms. alex On Thu, Jan 14, 2010 at 7:52 AM, Naftoli Gugenheim <[email protected]>wrote: > If you press delete then back what will happen? > > ------------------------------------- > Alex Boisvert<[email protected]> wrote: > > On Wed, Jan 13, 2010 at 6:10 PM, Naftoli Gugenheim <[email protected] > >wrote: > > > I haven't really used Ajax much but it seems to me there are two kinds of > > changes. > > 1.
