Using AJAX, many tasks that were traditionally performed on the server happen in the browser instead, resulting in fewer round-trips to the server, lower bandwidth consumption, and faster, more responsive Web UIs. While these outcomes are the result of offloading a good deal of work to the client, the browser still isn't the environment of choice for many developers who would rather have the full power and flexibility of server apps at their disposal.

Appcelerator's VP of Community, Matt Quinlan, gave an excellent talk to the Denver Open Source Users Group about his company's flagship product. Appcelerator seems at first blush to be another JavaScript framework wanting to make AJAX and UI widgets easier, but it does much more by bringing bringing delcarative, remotable messaging to HTML. Put another way: the Observer pattern is back in your web UIs, and it misses you.

I am very easy to make angry, and sometimes I get angry mostly for "nothing" or things I shouldn't get angry for. Though more often than not my anger is channeled so that in the end I often end up with something which is useful. Here is a comparison matrix against many of the commonly known Ajax TreeView controls in the world including ExtJS, Dojo, jQuery, Zapatec, Infragistics, Telerik, Ra-Ajax and so on and how they compare against each other... If you feel I should add another TreeView control to the mix or another performance parameter to the mix then PLEASE comment here and I WILL do just that...

Note that this is comparing mostly the Landing Pages (and in some cases the samples) of the given Ajax Frameworks. Ajax Frameworks included are jQuery, Prototype, MooTools, ASP.NET AJAX, GWT, ExtJS, ExtGWT and ours (Ra-Ajax) Please feel free to comment about other Ajax Frameworks I should add to the list or correct me if I've done something wrong when measuring...

ZK Studio start to support Eclipse 3.4(Ganymede) and fix several bugs.

And finally we have an Ajax TreeView Control :)

This tutorial will walk you through the steps of creating a simple database-driven AJAX application using Direct Web Remoting (DWR) 2.0, Hibernate 3.0 and a new open source project from Nexaweb Technologies, dojo.E. dojo.E is an extensible markup processing engine that out-of-the-box will translate XML into dojo components.

There are a few special techniques or effects that can spice up just about any web page. These are the top 20 Ajax effects that every web developer should know. They're essential parts of any web developer's toolbox. If you haven't seen them yet, you no doubt will in your future web development endeavors.

FlexChart is an open source Flash application built for uses in AJAX applications. The charting application is driven through dynamically through XML.

Following up to my previous post on Client-Side Javascript, I will be discussing a popular JavaScript framework called JQuery. JQuery is quite small in size (15kb) and this is a big reason that it appealed to me. For large desktop-like web applications, try out the extensive library of ExtJS. Now back to JQuery, its slogan [...]

Examples and Tutorials of JavaScript Tabs

Often I find myself doing a lot of "hand-waving" when trying to explain what it is Ra-Ajax and other server-side Ajax Frameworks are doing to people who doesn't know from before. To avoid that in the future I feel a "definition" or "word" to refer by is in its place for what separates GWT, ExtGWT, Anthem and Ra-Ajax from the JavaScript centric Ajax Frameworks like jQuery, Dojo and MooTools...

ASP.NET - Response time is very slow for the first request to application (45+ seconds)

Learn some of the new features of ASP.NET 3.5 - including LINQ, Update Panels, Update Progress controls, etc.

This weekend I got a chance to go two Dojo Developer Meetups and was impressed with all the things I saw the community doing with Dojo. Having been around since ~2004, Dojo has built up an impress list of functionality that makes every type of Ajax application easier to build and maintain. I wrote up my notes from the two days and break down the project into its piece to make it easier to swallow.

This tutorial gives you an explanatory overview of XMLHttpRequest Object. It introduces XMLHttpRequest object properties and methods in table. Working example code clarifies an AJAX use of this JavaScript object.

Jonas Jacobi and John Fallows, the founders of Kaazing talk of the need for two way communication and compare it with established request-response and Ajax models of communication. They also touch on how WebSocket can be used in JavaEE applications and its impact on existing architecture and code.

After four days of ASP.NET AJAX training with Stephen Walther I set out to learn more about my options in choosing a solution for a JavaScript/Ajax framework. If I realized days later I would be writing this comprehensive post on 7 of the most popular frameworks, I may have just went with the "Inny-Minny-Miney-Moe" method! I decided to share my research, analysis, links, resources, and personal grade for each of the frameworks compared - jQuery, YUI, Prototype, Dojo, MooTools, Ext JS, and Script.aculo.us

Ajax Push gives the server the ability to update any part of any page at any time, transforming every application into a new communication tool, connecting users to each other through web server mediated channels. In this session, recorded at the recent JSFOne conference, Ted Goddard provides an overview of Ajax Push and its range of uses in multi-user web applications. By stepping through the development of a multi-user slideshow and chat system, he shows you how easily sophisticated Ajax applications can be created.

Douglas Crockford’s “JavaScript: The Good Parts” qualifies among the top 3 books on JavaScript ever written. Its concise, terse and full of gems, which you otherwise have to glean from the stacks of information out there on the web. Yahoo! also published a video, where Douglas Crockford speaks on the topic. Watch it now!

As a Rails programmer, I have been using Prototype and Scriptaculous for over a year and a half, solely because it comes packages with Rails and has helpers. About 3 months ago, I discovered JQuery, which is another Javascript library that combines the powers of Prototype and Scriptaculous into one. JQuery is very easy to install for your web app and has a TON of cool things you can do with it.

Now that the news has hit the blogosphere, I'm seeing lots of questions out there about the jQuery/MSFT announcement.

Ajax has been around for yonks now and it’s not news. However, many people seem to still shy away from learning JavaScript. Having JavaScript or more specifically ECMAScript under your belt is really beneficial. JavaScript is used in many areas other than the browser; ActionScript, FireFox’s Plugins, Server side (i.e. Aptana Jaxer), Google’s V8 and various others. To mention a quick extra note on V8 as its fairly new news, its the JavaScript engine behind Google Chrome however its standalone and can be used in any project you wish. Find out more about it at the V8 webpage. It’s a good way to get into dynamic programming if you are more used to languages such as C# and Java. This is a list of the things I think you should check out if you want to learn JavaScript.
