Why Microsoft and Google are Cleaning Up With AJAX 443

Posted by CmdrTaco from the i-remember-when-center-was-cutting-edge-web dept.
OSS_ilation writes "Google uses it, and Microsoft is pursuing it, so there's a lot of hype and hubbub surrounding AJAX (Asynchronous JavaScript and XML). AJAX brings together some hot properties, JavaScript, HTML/DHTML and HTML, according to Julie Hanna Farris, founder of Scalix, a Linux-based, e-mail systems vendor. Scalix is using AJAX in Scalix Web Access (SWA), a Web-delivered, e-mail application. AJAX enables advanced features like drag 'n drop, dropdown menus and faster performance capabilities, which are now making their way into Web applications, she said. These kinds of capabilities represent a significant leap in the advancement of Web apps."

But it is still using HTML/CSS for the UI. The HTML/CSS document model simply doesn't work well for desktop quality applications.

    The truth is that the stuff we've seen in AJAX so far is nothing. I don't know about anyone else, but I've used it in regular webapps as nothing more than an interface enhancement. People don't even really notice the fact that the web pages work much smoother.

        It certainly matters. However, it doesn't matter quite as much as the hype suggests. AJAX is a very valuable technology, but the only reason why it's catching on now is that we've finally rid the web of early browsers like Netscape 4. Now that everyone has full JavaScript and DOM, we can finally build complex interfaces. XMLHttpRequest is just icing on the cake. (Hidden IFrames did the job just fine in the past, and are still more useful for some interfaces.)

          Not everybody has JavaScript and the DOM, and it was never a crucial factor anyway.

      Well, the truth is AJAX is not in Microsoft's best interest. The internet in general is bad for Microsoft. They were way into interactive TV and stuff. They really would prefer that they be the gateway to the web and that you pay $$$ to them to be able to get the content as well as selling their OS. AJAX makes windows less relevant because you can run apps on firefox on any platform. So, I can understand why they wouldn't use much of it. However, as always denying a good technology is a mistake. You can see this as a form of protectionism that backfired on them.

      Which comes as quite a surprise to everyone that's been doing the following since the mid 90s.

      Create a frame driven page with one main frame and one tiny frame.
      Whenever you want to perform an asynchronous action:
          Load a page in to the small frame.
          Have that page call an onload event that accesses a function in large frame.

      All "AJAX" (which is just a dressing up of what was already there) does is use the request object which is just a cleaner way of what people have been doing for about ten years anyway.

      There were also tricks for doing it with Java. But Microsoft had to supply an alternate mechanism because someone took Java out of the dominant web browser for a while. Can't think who might have done that though.
      • I've made the invisible frame and multi-frame pages before to emulate what AJAX can do natively now. And not only did it suck designing them, but in the case of live time updates, you get the constant 'click' noise in the background every time the invisible frame reloads. A rather irritating draw back.

        But I agree with you, AJAX definately does the same thing in a much better and cleaner way.

    • OWA looks and works like ass in firefox though. It's IE only for all practical purposes.

      Microsoft invented XMLHttpRequest because before that people were using tiny little java applets to accomplish the same thing. In fact the original version of remote scripting in IE also used a java applet. When MS decided that java was the enemy they figured a way to do it without java.

      I for one see no need for AJAX, it's better to just write java applications or even applets (or thinlets).

    I think that if AJAX picks up and starts to be used everywhere, we should standardize a system so that optionaly, a web browser can inform the server that it has the option to connect to it using an open port on that system. It would really help things if the browser didn't need to connect to the server every few minutes to check for new data. That way, instead of my browser connecting to Gmail's servers every 60 seconds to check for new mail, Gmail's servers can connect to my browser and tell me only when I have new email.

Maybe Java is just too slow (and here come a dozen posts claiming it's not). Maybe the wait time to load a JVM into memory, plus download an applet is too long.

    If you are typing on a web page that uses XMLHTTPRequest, then you should treat it as if you were running a live program remotely. I.E. the web page could forward information about everything you type, how you move your mouse, etc, without an explicit 'submit'. Example : it if were an email app, and you typed 'my boss is a dick and my SSN is 555-55-5555' in an edit control, and then thought better of it and erased what you typed and killed the browser window without submitting, the contents could already have been captured and forwarded to the host with XMLHTTPRequest and you never knew it. Looks like a good cross site scripting opportunity.

    Of course, you usually don't know if a page is using XMLHTTPRequest in a hidden frame unless you look really hard, so I guess the bottom line is never type anything on a web page you don't want the world to see. On the other hand, AFAIK (which doesn't mean much) this hasn't shown up in practice, so maybe it isn't that big a deal.
    • Thats what I said in The Fonz uses AJAX to spy on you [webeisteddfod.com] (ajax-fueled text adventure included) - but as everyone will point out to you in overly angry tones, that could have been done a zillion years ago with a hidden iframe. I think the difference now is that people are thinking about how to apply ajax, so you are gettin all sorts of new and cool applications. Which also means you are getting all sorts of new and evil applications :)
  • Many of us do web development in environments that REQUIRE accessibility and nonvisual functionality. Most major corporations and media sites, all government sites, and most non-profits require that their web properties be open and functional for all of the webs users. Unlike traditional websites...or even traditional applications...AJAX webapps are typically unusuable for anyone with any kind of disability that requires assistive software.

  • What does the article mean by "cleaning up"? Regarding MS and Google, I'd expect it to mean "making a lot of money", but that's not supported in the article. In fact, recent news shows MS thinks it's missing out on business by not doing enough AJAX - hardly evidence they're making a lot of money off of it.

    Maybe the writer means "tidying up". Like hiding software problems on a backend that is maintained without the users noticing upgrades or details of failures. Maybe just putting a thin-client cross-platfor

  • I prefer AJASON - that is, replace XML with JavaScript Object Notation or, serialized javasacript objects. It parses much faster and easier than XML.

    I have a JSON class for PHP which lets me serialze any PHP object into JSON. I can send the JSON to the client, eval() it with javascript and viola, my PHP object is now a JavaScript object.

    The only problem with it is that there isn't an object serializer built into JavaScript (that I'm aware), so sending data back to the PHP script isn't as easy. I haven't

    AJAX, being a random collection of JavaScript hacks, doesn't offer any accessibility.

    So you can't use it in software that might be sold to, for example US Government customers -- no national laboratories, no NASA, etc.

    UNLESS -- you write your own accessibility aids and write your own UI framework that compiles into both an AJAX version and a web accessible version.
    That's a tall order. However, there is help.

    You can write your web pages in HTML with XForms and let XForms handle the dynamic page aspects, and then offer up the HTML+XForms as the accessible version. (See the DHTML Accessibility Roadmap [w3.org].)

    Everything that the AJAX cloud of applications does with the XMLHTTP object and updating the DOM on the fly to display choices can be done with XForms.

    Then, you can use one of these mechanisms to convert the server-side XHTML+XForms file into AJAX:
    • FormFaces [formfaces.com] A pure AJAX library that runs in today's browsers. It's stunning to see how simply this works.
    • Chiba [sourceforge.net] A server-side engine in Java that integrates with TomCat or other Apache web server technologies to produce HTML that works in today's browsers. Plus, the plain-old-HTML output of Chiba is accessible right now, in addition to the XHTML+XForms file itself. (Caveat: Full AJAX implementation is in development, according to the mailing list.)
    • Orbeon Ops [orbeon.com], like Chiba, Orbeon converts to HTML for today's browsers in its Java back end, but rather than integrating into your TomCat or Coccoon framework, it comes with its own framework that helps you separate presentation from content and write your applications.


    If you want to serve up the XHTML+XForms directly, and not rely on any AJAX technologies, try these:
    • Mozilla XForms [mozilla.org] for Mozilla and FireFox, an XPI that's available for recent betas and nightlies, this one-click install adds native XForms support to these browsers. Still in Beta, but with plenty of developers, it should be a full implementation.
    • FormsPlayer for Windows [formsplayer.com] provides full support for XForms in Internet Explorer via a plug-in. Plug-ins are not everyone's cup of tea, but then neither is Mozilla ;-). You can get the AJAX benefits of dynamic page updating and yet still retain accessibility with any of the server-side or JavaScript engines above, but if your target deployment is Internet Explorer, you can gain tremendous access to advanced features inside IE with this plug-in. (Plus it has some neat Konfabulator-like tools such as SideWinder.)


    So, try them out, and see how much easier it is to write accessible code and properly separate your data and presentation layers when you use XHTML, CSS, and XForms. Then, choose a middleware solution or a browser-based solution and go forward knowing that you can meet architectural requirements without getting bogged down in JavaScript toolkits.

      This irritates me. This is not true. And yet moderators without a clue have pushed it up to +5, Informative. And any newbie web developers who read this are going to think that they have to choose between AJAX and accessibility. Some of them are going to choose AJAX and not bother with accessibility. If your post had been down at -1, Wrong, they might not get that impression, and would go on to write accessible AJAX web applications.

      You don't have to choose. You don't have to write "UI frameworks" that you have to "compile". That's nonsense. What you do is you write the non-AJAX version, and then you add the AJAX as an optional extra. When people have Javascript turned off, they get the basic version seamlessly. Perfectly accessible, none of the complicated nonsense you claim is necessary.

      Please stop propogating this myth. If you want to promote your favourite technologies, then by all means do so, but don't lie about the alternatives to make them look bad.

    I don't think there are too many screen readers our there that can handle AJAX quite yet.

    Hmm.. screen reader built onto Firefox? Notices when stuff changes. I could build that. Sweet.
