Ajax Sucks Most of the Time

Vo0k writes "It seems that everyone is excited with what AJAX promises, and only few look at what it breaks as well. The article at Usability Views offers a critical view at the new Microsoft technology, pointing out some problems it creates, like breaking bookmarking, making the 'back' button useless, problems with printing, accessiblity and more. The single-sided view from the article provides a good counter-balance for all the craze."

as in all new directions...

Up front Disclaimer: I realize the article is "just saying no to Ajax" with constraints. My post here is to the objection I think the article states Ajax problems too harshly.

Reading the article it seems to me:

• most of the listed grievances are not unique to AJAX, have been addressed in the past, and are probably soluble for AJAX too. (e.g., how many remember the broken first browser paradigms where there simply was no easy way to get the information from a web page to some printer? It's not perfect today, but it's doable. This problem is ultimately soluble for AJAX too)
• AJAX is the (to many) latest and greatest. Many will hold on and gain purchase. Some will bail. I think AJAX or some derivative thereof is here to stay. Like technology before AJAX, there will always be naysayers, and there will always be glitches. For this to justify a "Just Say No to AJAX" philosophy is naive and maybe even misguided.

From the article:

Ajax is currently so hard to learn that many page authors write buggy code.

Huh? So? Is this unique to only Ajax?

Also from the article:

Many websites that offer users a choice between regular and ajax versions have found that most users prefer ajax-free designs.

When an article wants to rant or complain about a technology, an un-cited and broad statement like this is a huge red flag. It doesn't state what the percentages are, it doesn't state the reasons for preferences. In the middle of an article espousing "no Ajax", this is a non-sequitor. Please expand.

I'm having great fun experimenting with AJAX and am getting interesting new approaches for old solutions improving customer and user experiences. I'm not about to walk away from this until a more thorough trial. So far I'm liking what I'm seeing. Yeah, there are glitches to solve, isn't that kind of what we're here for?

It is worth noting this statement at the bottom of the page.

This is a spoof article. Please compare it with the original and you will see how little it has been changed.

That said some of the points are valid, but the article was basically showing how those same things were valid at one point for using frames as well.

Re:as in all new directions...

[diverman]

I am glad that you made this statement. The whole time I'm reading the article, I kept thinking that it was basing the vast majority of its argument on false assumptions that AJAX is predominantly being used on content pages. The best use of AJAX, that I see, is with improving user interactivity with a web application. Web applications are becoming more and more of a need, and I think this is where AJAX is gaining the most ground.

The author talks about how "the page" is the basic idea that was behind the Web. Well, I hate to break it to him, but after 12+ years, things have evolved. The notion of the page has long since been an area of limitation with web applications and usability. This is why we've seen the uprising of many technologies in an effort to have more dynamic content interfaces. Users don't like having to wait for a full page load to make a small request within an application. There is complaint about the time it takes. Granted, this is largely a perception thing, but it is the reality of users.

The type of information being presented on the web has gone beyond thesis papers and simple static articles. The information that users are becoming used to is more complex, as the average user's understanding of relational information grows.

Now, the author does make some good points... but mostly these are when using AJAX in "pages". In this respect, I agree that overzealous, and possibly inexperienced web developers have gone overboard. But a good web developer considers the effects their choices have on a user, and they make the choice to go with one advantage over the loss of another. I am conscious that search engines can't necessarily index my content... so what! If I don't want it to be indexable, so be it... they can index the more "content" oriented parts of my sites, and users can then find the "features" and applications that use better technologies. The complaint about printing... please! A best practice is to take length articles and break them up into multiple pages. Ummm.. this has the same problems with printing. He kind of neglects to point that out.

As was stated previously, many of the arguments are presumptuous that the web is all about "pages". I also question the interpretation of his statistics. 1. Old browsers are likely unpatched browsers. With the vulnerabilities and security issues today, compatibility with AJAX is the least of their problems. Upgrade! 2. Mobile browsers have problems with MOST page content. Websites are designed for a minimum of 800x600 these days, if not 1024 wide. Websites still need to provide special pages to serve up content to mobile devices anyway.

So, I know this is a spoof article by the author about a previous article about Frames back in the 90's... but I think he sticks too much to the premise that existed back then, that the web was all about simple content and "pages", without recognizing that the information complexity has evolved, and that "applications" are becoming more and more necessary for usability of the information. Yes, improvements are needed. Yes, back button support should be support (but not required). Also as was said in an earlier post, many of the problems are not an issue with just AJAX, and many are an issue with the lack of understanding of the effects of the choices made when using ANY new technology.

Implementation

[kevin_conaway]

Its not the technology, its the implementation that causes those errors. You can misuse ANY technology to f things up. Why should this be any different?

This is the Internet. You can say "fuck" here.

ajax

[rayzap]

ROTFLMAO AJAX is no different than any other programming set of tools. If used correctly it rocks, otherwise it sucks. We use it a lot in our web application and it has provided us the ability to deliver greatly enhanced interactivity and reporting. It's kinda like the blind date that gets overly hyped. The reality will never match the hype even if she was pretty.

Not always that bad.

[MartinG]

The web is used (rightly or wrongly) to deliver two distinct things.

1) Content.

2) Applications.

For (1) ajax _does_ suck most of the time for all the reasons stated, but for (2) is makes sense because it makes the app behave more like a desktop app. "back" and "bookmarks" stop making sense anyway. You wouldn't expect to have those features in your desktop apps, so why in an app delivered over the web.

The great shame is that these two opposing requirements have not forked into the data-web and the application-web. Things went wrong IMO the day someone thought of putting forms in html.

Flash

[nmg196]

Nearly all of the problems cited in the article are present to a FAR WORSE extent with fewer workarounds if you write your website so it makes heavy use of Macromedia Flash. That includes problems with bookmarking, back button not working, no printing etc. Yet Flash is used on millions of major websites. As other posters mention, the problem is not with the technology but misuse of the technology.

Some flash developers get what I call "flash happy" and write the entire website in flash. This is lunacy. For a start, (and this is possibly a problem with AJAX heavy sites too) your site cannot be indexed by any search engines if it's navigation is entirely flash based. No search engine in the world is going to evaluate your flash files or run your AJAX scripts in order to attempt to crawl the site. If AJAX is used sparingly where necessary, then I'm pretty sure it won't cause any major problems. It's not like Flash seems to have suffered...

Umm... Its a SPOOF

[dsginter]

Read the bottom of the page. The article is a spoof.

Re:Jokes often become "common knowledge"

[killercoder]

Ummmmm, I hate to do this - god I hate to do this, but I'm actually going to support MS on this one.

The paradigm of Ajax: "The transfer of XML to a web page in the background so that javascript can load data/initiate actions without loading a new page" was in fact a Microsoft innovation. They shipped it with Internet Explorer 4 and the first packaged MSXML controls.

I was writing applications of this type over 7 years ago targeted at Internet Explorer 4. The latest incarnation of AJAX still uses the MSXML parser on IE Browsers, but extends the support to FireFox and Netscape variants.

Please note, Microsoft did not coin the term AJAX, but they did do it first.

I know I'm going to hell for this.

Re:Microsoft?

[amliebsch]

And it most certainly is NOT and NEVER WAS a Microsoft technology. Microsoft has nothing to do with the new widespread adoption of AJAX. This comment in the article really really bothers me. Microsoft deserves absolutely no credit for things they had nothing to do with.

Correct me if I'm wrong, but didn't Microsoft invent XMLHttpRequest? In which case, most AJAX, which uses XMLHttpRequest, is in fact built on Microsoft technology, and they deserve credit for having a played key role.

Re:Microsoft?

[clear_thought_05]

You are correct. It was first Microsoft's idea.

Microsoft first implemented the XMLHttpRequest object in Internet Explorer 5 for Windows as an ActiveX object. Engineers on the Mozilla project implemented a compatible native version for Mozilla 1.0 (and Netscape 7). Apple has done the same starting with Safari 1.2.

http://developer.apple.com/internet/webcontent/xml httpreq.html

The wiki is wrong - history lesson

[brunes69]

AJAX relies on the XMLHttpRequest object to do anything. Without it, there is no AJAX (you could say it puts the A in AJAX). Microsoft invented this object, it has shipped with the MSXML COM object for a long time. They first used it in Outlook Web Access in the late 90s.

AJAX only started to get popular in the media after Adaptive Path coined a stupid buzzword for it, but IE-specific developers had been using it for years. Adaptive Path just stumbled upon it being more sueful because Firefox started also shipping an XMLHttpRequest object.

But Microsoft *did* create it, so it is totally accurate to call it a "Microsoft Technology". Just like SMB networking is a "Microsoft technology", even though there is Samba, and .Net is a "Microsoft Technology", even though there is Mono.

All of this can be solved

[alphorn]

The problems mentioned can all be avoided.

• The back button can be made to work. We went to great lengths to make sure the back button takes you to the previous view in http://map.search.ch/ . Try clicking it for a zoom, then hit the back button.
• The fact that URLs don't auto-update doesn't mean that permalinks are impossible. We create a permalink every time you do a search or enter the "email this page" screen. See http://map.search.ch/zurich
• Even auto-updating URLs when navigating inside an AJAX app are possible, we have plans to implement that in the future.
• And of course, our map works just fine without javascript. http://map.search.ch/?s=1

And yes, we've had all of this from day one - months before google maps. Admitted, many AJAX apps still dont bother to do any of this - I'd say let's adress that instead of abandoning AJAX.
