XmlHttpRequest

XmlHttpRequest 06/01/2004 06:51 PM

I recently mentioned XmlHttpRequest to a collegue as possible solution to his problem and found that he didn't know about it despite the fact that many DHTML apps are simply impossible to do without it.  As I mentioned before, people tend to stop looking around when they are busy.  Well, even meercats know better...

FYI, XmlHttpRequest allows you to make HTTP requests and process responses from within a webpage.  It was first implemented by Microsoft as an ActiveX object.  The shocker is that it's now considered nearly ubiquitous because other browsers support the feature as well.  For more info, here are some useful links to get you started:

• Using the XML HTTP Request object - detailed how-to article.
• Microsoft's IXMLHTTPRequest doc
• Apple's XmlHttpRequest doc

Have fun.

Object

Dynamic HTML and XML: The XMLHttpRequest
Object 05/15/2004 09:42 PM
As deployment of XML data and web services becomes more widespread, you may occasionally find it convenient to connect an HTML presentation directly to XML data for interim updates without reloading the page. Thanks to the little-known XMLHttpRequest object, an increasing range of web clients can retrieve and submit XML data directly, all in the background. To convert retrieved XML data into renderable HTML content, rely on the client-side Document Object Model (DOM) to read the XML document node tree and compose HTML elements that the user sees.

AJAX

AJAX 03/22/2005 04:58 PM

I am playing with AJAX myself but I see many problems with AJAX as the next generation DHTML application platform.  AJAX applications are more expensive to build, test, and update than traditional DHTML applications.

Frankly, I am not even sure whether current crop of popular web browsers can support AJAX because they weren't built with the expectation that a signle web page might stay up for as long as GUI applications.  When even small carefully written DHTML apps can cause enough browser resource leaks to require frequent browser restarts, I think good stable AJAX applications will be rarer than the picture recent hype paints.

And by the time engineers discover the cost of AJAX first-hand, .NET-based ClickOnce applications will look much more attractive than AJAX-based applications can ever be.

Now just call it "AJAX" 03/14/2005 05:25 PM
Last year we wrote about how some applications -- notably Google Mail and Suggest -- were taking advantage of Javascript plus XML-over-HTTP for richer interfaces. Now Jesse James Garrett of Adaptive Path has written a nice summary and (perhaps more imporantly) come up with a new name for the approach: "AJAX." Some CMS vendors are beginning to use AJAX methodologies, although from what we have seen mostly in a tentative way (if you're a vendor using AJAX, do tell where and how. Asynchronous communication with the server has tremendous potential to make heretofore very linear authoring and workflow procedures in a CMS much more fluid and therefore more, well, lifelike......

AJAX in Flash

AJAX in Flash 03/30/2005 09:01 PM

As I pointed out in my AJAX post, I think difficulties of writing AJAX make it a poor web application platform, particularly since there are easier alternatives.

Flash, for example, is a better platform for some applications than AJAX because it offers similar capabilities (i.e. XMLHttpRequest in DHTML) and comparable, if not better, level of availability along with much better graphics capability.  Flash tool developers such as Lazlo and Xamlon makes it easy to develop interactive web application.  Just take a look at this Google Maps like demo built over a weekend using Xamlon's upcoming tool.

Note that AJAX in Flash is inappropriate for web applications that manipulate DHTML DOM extensively and has a number of issues that makes it prohibitively expensive for uses beyond demos and small tightly-focused applications.  For example, you can't built PhotoShop with it without abandoning usability.

Beyond Flash, .NET looms with superior functionalities and flexibilities.  The only thing it lacks is the availability in several sense.

Why the term Ajax is useful

Why the term Ajax is useful 04/18/2005 09:55 PM

Software design patterns are useful mainly because they provide a shared vocabulary: rather than discussing the intimate details of a three layered application architecture, we say "MVC". Rather than describing an object that tracks your progress while looping over a collection, we say "Iterator".

The same is true for Ajax. While the techniques it describes have been around for years, grouping them under a single term is extremely valuable for raising the level of discussion about them. No longer will we have to explain XMLHttpRequest / hidden iframes / crazy cookie tricks in depth when discussing sites which pull fresh information from the server without reloading the whole page. Instead, we can say "Ajax" and move on to more interesting things.

Matthew Haughey says it's all about marketing. I disagree; it's about smarter and more effective conversations.

AJAX Considered Harmful

AJAX Considered Harmful 03/17/2005 02:49 AM
I intend for this to post to be constructive, so I will focus on two specific suggestions which hopefully will serve as the seed for the development of a set of best practices for AJAX.  Here are the two humble suggestions on things that people should standardize on ...

Will Ajax Hurt Usability?

Will Ajax Hurt Usability? 03/29/2005 01:28 AM

I'm curious what effect Ajax will have on usability. With this technique, the unspoken nature of Web apps is changing, and apps using Ajax will likely do things that users don't expect.

When I first starting using client-side HTTP requests back in 1999 (long before the snazzy name), I did it really badly. I wrote an intranet phone directory which used background HTTP calls from the browser to retrieve the data and load it into a DIV on the interface without re-loading the page. It worked great, but if the users wanted to find another phone number, they always pressed the "Back" button...and got sent backwards, out of the phone lookup system.

Web users have a "user model" of how forms work (we discussed user models in this post). Web users are accustomed to the fact that nothing happens on a form until they hit a button called "Submit" or "Save," and that this gives them a new page, so they can usually hit "Back" to get back to their form input. I broke this user model, and the user paid the price.

With Ajax, it's easy to break the model of stateless request and response that users are subconciously aware of. You shouldn't do this lightly or you're going to get some confused users.

Here's a current example:

37 Signals' great Ta Da Lists use Ajax to "check off" items in a list. If you click the box next to an item, it's immediately removed from the list in the interface and a request is dispatched in the background to change the item's status on the server.

I understand this and it's quite slick, but what about people who don't spend as much time with this stuff as I do? I know a lot of people that look at a list of checkboxes and think, "I can check a bunch of boxes, then review my selections before finding and clicking a button called 'Submit' that's got to be around here somewhere."

This is the user model that a lot of people have for Web forms. They get to do whatever they want, and nothing counts until they press "Submit." I like Ta Da Lists, but I think 37 Signals made a mistake here. I'd be curious what feedback they've gotten about it.

Where we're going with Ajax is to allow developers to really mess with the unspoken "rules" that users have gotten used to. Ajax is great and provides a revolutionary way to do things, but I know some people will take it too far, too fast. User confusion won't be far behind.

Ajax: A New Approach to Web Applications

Ajax: A New Approach to Web Applications by Jesse James Garrett
http://www.adaptivepath.com/publications/essays/archives/000385.p hp

Ajax isn’t a technology. It’s really several technologies, each flourishing in its own right, coming together in powerful new ways. Ajax incorporates: 1) standards-based presentation using XHTML and CSS; 2) dynamic display and interaction using the Document Object Model; 3) data interchange and manipulation using XML and XSLT; 4) asynchronous data retrieval using XMLHttpRequest; and 5) JavaScript binding everything together. This essay by Jesse Garrett explains Ajax and what the future holds for this exciting application. This has been added to eCommerce Resources Subject Tracer™ Information Blog.
