Introduction Ajax is a combination of technologies that increase web page usability. It is an acronym for Asynchronous JavaScript and XML. Ajax performs its functions by encoding all requests between the server and the browser in the common programming language of JavaScript. Communication between server and browser in a standardized language like JavaScript and the Ajax XMLHttpRequest object allow for page updates to occur asynchronously through

CAPTCHA is a simple test to determine if a user is a computer or a human. It is used to prevent spam abuse on the websites. So if you use CAPTCHA on your web site forms, this can help in stopping some bots and making life harder for other bots in accessing or using your forms. The goal of this tutorial is to demonstrate how to make your own simple CAPTCHA protection using PHP and AJAX technologies.

Ajax can be a great way to enhance the user experience of a website. This guide discusses the basics of ajax and introduces useful javascript functions and properties involved in implementing ajax features from scratch. Basic dom-based javascript knowledge is assumed. PHP is used for the discussion of the server-side support.

This tutorial shows how to create an Asynchronous JavaScript and XML (Ajax) client-side slide show that's animated using "Ken Burns Effects." You'll discover how to build XML data sources for Ajax, request XML data from the client, and then dynamically create and animate HTML elements with that XML.

MooTools is an open source JavaScript framework that evolved from the simple function called moo.fx. The developers of moo.fx have slowly expanded this simple function into a fully functional framework. As of this writing, the framework is on its 1.2.0 version and has been enjoying a good following along with other JavaScript frameworks. MooTools is a lightweight framework. But do not think MooTools is another lightweight framework that would eventually stack-up. This framework is as lean as they could be. Instead of stacking up the functions and lines, MooTools divide the codes by developing functions in small code bases.

The method for getting information through an implicit request can be applied not only for technical dictionary. Have you ever wondered about the double underlined links in such projects as hotscripts.com and devarticles.com? This is context-dependent advertising based on IntelliTXT engine from Vibrant Media (www.vibrantmedia.com). When the mouse cursor points to such a link an advertisement window appears. This technology is referred to as in-text advertising. This method is also increasingly used on news portals. The main page contains only the news headings. Yet when the user puts a mouse cursor over the heading a short description appears. Thus the main page can hold a lot more news. The visitor sees the headings and all he/she has to do to get a short summary is to browse through the items with a mouse cursor. Let us now look into how contextual help can be implemented with AJAX.

This article guides you through the Ajax basics and gives you two simple hands-on examples to get you started.

In this article, the first of three parts, you will start creating a simple web-based POP 3 client using AJAX, which will use "XMLHttpRequest" objects to retrieve messages from a mail server.

Developing an Ajax based application with minimal JavaScript coding is possible with the use of VS 2005, ASP.NET and a simple but powerful library called Anthem.NET. This open source library might not be popular but it has been given a pretty good ranking as it provides any developer the ability to build an Ajax based website without using too much Ajax. As you may have already noticed, it uses a lot of frameworks and software development tools to compensate with the minimal use of JavaScript. To use Anthem.NET you need to fire it up first in ASP.NET. Basically, you will just have to use the libraries DLL as a reference point to make it work. It is really simple at first glance but apparently Antem.NET�s DLL is not precompiled first. Make sure that you compile the project carefully as the DLL could get extracted in different places.

This PHP5 class allows your Prototype JavaScript AJAX applications to natively call PHP methods and get data back as if the methods were written in JavaScript. I modeled this somewhat after AMFPHP for Flash remoting. I wanted to be able to simply write methods in a PHP class and then call them in JavaScript and not write any more code than that. This pretty much does that. You can see it in action at my website: http://onesandzeros.biz/j sphpremoting/

Ajax is a great helper to us while developing rapid applications without worrying us at power of asynchronous. In Visual Web Developer 2008 comes with built in Atlas and ASP.NET3.5 . In this tutorial, I try to show you what's ajax and database querying at same time. Now let's build our scene. Open an empty web site and dop a ScriptManager and UpdatePanel from Ajax Extensions tab. Close the tab and open standard controls and drop one textbox and one button. Place a label inside ajax control and one more outside of UpDatePanel. The second label will display that we are using Ajax and page is not posting back. I will add some hard codes and I have put s SqlDataSource and a GridView. Complete code is included

Additional content, or decorations, can be loaded after the basic content is displayed by "including" an external file with an AJAX call.

The GSmapSearchControl Solution is a simple to use application of the Google AJAX Search API that is designed to let you easily add a searchable map to your pages, sites and blogs. The rest of this page discusses this topic in detail - but if you just want to cut and paste some code, the �hello world� of the Map Search Control solution is available at the end of this article.

Thanks to Ajax, we can provide real-time feedback to the user using server-side validation scripts and eliminate the need for redundant validation functions without giving up a solution that degrades gracefully when JavaScript is disabled.

Excellent tutorial on how to build an Ajax-powered Web site, with dynamic page loads.

Here we will be developing a search feature. By using this feature the users will be able to search for a particular person in a list stored on the web server in text format.

Qooxdoo was released in the first quarter of 2006, Qooxdoo differs itself from other Ajax enabled frameworks because it uses JavaScript as its tool for development. Most Ajax based framework that we know of either uses other Java or other languages since its primary aim is to help developers build an Ajax based application or framework. This framework uses JavaScript. It does not apologize in doing so for one good reason: this framework is geared to build an effective client side application. Somehow, this is a refreshingly unique framework when compared to different frameworks that we use today

In this quick tutorial we will show how-to create such an Ajax upload form using the jQuery Form plug-in and our easy upload class.

Script.aculo.us lets create sortable lists which can be synchronized with the back-end with AJAX.

In the first part of this tutorial we’ve learned how to browse the file system. Now we’ll learn how to deal with files and folders actions, like open, copy, move and delete. This tutorial will show you how to create a cross-platform mobile file explorer using web technologies like PhoneGap/Cordova and jQuery Mobile UI. This is a two part tutorial, the first part contains the browsing part of the folders and files from your file system device, and the second part contains implementation of the actions that can be made with the folders and files, like open, copy, move, delete.
