Ajax Back, Forward, Reload and PHP

IdaAshley writes "A major challenge of Asynchronous JavaScript and XML (Ajax)-driven Web sites is the lack of a Back button. Mike Brittain discusses ways to get around this obstacle in part 1 of the 'Developing PHP the Ajax way' series." From the article: "The Web is a page-by-page medium. The backward and forward buttons on your browser's toolbar direct the browser from page to page. When Macromedia's Flash became all of the rage, developers and users started to see how Rich Internet Applications (RIAs) break this metaphor. You might click around a few sites, land on a Flash-based Web site, then click around in it for a few minutes. One click of the Back button and the ride is over. Rather than going one step backward within the Flash site, you completely lose your place."

Stupid

This is terrible, and does nothing to make the back button in the browser work. At best, it gives you an undo/redo in the applications. The back button not working is more of a symptom than the actual problem, and if widely implemented this kind of workaround is only going to distract and make it less likely that the actual problem get fixed.

That has been discussed to death and known for years. You do it with a hidden iframe and anchor links (#blahblah). That's the gut of the whole deal.

Tools that Support This

[MikeyTheK]

We already know that Morfik and GWT support all of these features, but does Script# or Atlas, yet? I didn't think so, but my memory may be faulty. Even more importantly than knowing how to support is not having to know how to support it. Thankfully AJAX is advancing so quickly that articles like this are going to be less and less relevant since more and more tools will just implement the features right out of the box.

Already been integrated into browser

I'm 99.5% positive that Adobe Flex can help address using back/forward buttons in the browser and Google has code to do this with Ajax. If I'm not mistaken, Gmail no longer croaks if you try using back/forward now. I'm at work and don't want to take the time to look up the links, so (hopefully) free mod points to whoever feels like posting some links to this stuff!!

That being said, the article is garbage. People ARE integrating it into the browser controls... no point in using this crappy method. Fact is, most users will, through force of habit, use the back/forward buttons, or mouse gestures, or keyboard shortcuts.

Back Button Not a Problem

So says you. I say: if it makes sense for a user to hit your back button, why are you using Ajax? Do users hit their back button when they're using native desktop applications? Sounds to me like you're just to ajax-ify a traditional web application for the heluvit.

Well, no decent GIS application lacks a back button.

I don't track too many AJAXy sites, but I should think anything where you can have a significant
change in scope of the content presented (particularly when it makes up the bulk of the page and
there is little else in the way of controls or context) ought to allow the user to go back to a
previous scope. Mail box to mail box, browsing a nested discussion.

Isn't that the same reason everyone else is doing it?
