There are a few AJAX demos and examples on the web right now. While these are invaluable to learning AJAX, some people need a bit more information than just a raw piece of code. In todays environment there are many ways to learn AJAX including, books, classes, conferences, workshops and tutorials. Of these the only one that is free and accessible to everyone are web-based tutorials. The following is a list of what I consider the be the best and most helpful AJAX tutorials that I've found over the past year.

Ajax and XMLHttp Request from webPasties
The Ajax Make request with asynchronous
Most Web applications use a request/response model that gets an entire HTML page from the server. The result is a back-and-forth that usually involves clicking a button, waiting for the server, clicking another button, and then waiting some more. With Ajax and the XMLHttpRequest object, you can use a request/response model that never leaves users waiting for a server to respond. In this article, Brett McLaughlin shows you how to create XMLHttpRequest instances in a cross-browser way, construct and send requests, and respond to the server. First, take this last bit of overview before you dive into code -- make sure you're crystal clear on this idea of the Web 2.0. When you hear the term Web 2.0, you should first ask, "What's Web 1.0?" Although you'll rarely hear Web 1.0, it is meant to refer to the traditional Web where you have a very distinct request and response model. For example, go to Amazon.com and click a button or enter a search term. A request is made to a server and then a response comes back to your browser.
Advanced requests and responses in Ajax
In the last article in this series, I provided a solid introduction to the XMLHttpRequest object, the centerpiece of an Ajax application that handles requests to a server-side application or script, and also deals with return data from that server-side component. Every Ajax application uses the XMLHttpRequest object, so you'll want to be intimately familiar with it to make your Ajax applications perform and perform well. In this article, I move beyond the basics in the last article and concentrate on more detail about three key parts of this request object:
* The HTTP ready state
* The HTTP status code
* The types of requests that you can make
In Web applications I've seen numerous -and personally implemented a few ways to rearrange items in a list. All of those were indirect interactions typically involving something like up/down arrows next to each item. The most heinous require server roundtrips for each modification boo. With sorting vertically oriented items under our belt, onto the next challenge: sorting floated, wrapped list items. Earlier versions of my code had separate scripts for vertical, horizontal, and wrapped lists. Now they are unified into one script that does it all.
Ajax Building a Drag and Drop
The Better a Ajax and
Browser-based file uploads, in particular those involving the HTML <input type="file"> tag, have always been rather lacking. As I am sure most of you are aware, uploading files exceeding 10MB often causes a very poor user experience. Once a user submits the file, the browser will appear to be inactive while it attempts to upload the file to the server. While this happening in the background, many impatient users would start to assume that the server is "hanging" and would try to submit the file again. This of course, only helps to make matters worse. In an attempt to make uploading of files more user-friendly, many sites display an indeterminate progress animation once the user submits the file. Although this technique may be useful in keeping the user distracted while the upload being submitted to the server, it offers very little information on the status of the file upload. Another attempt at solving the problem is to implement an applet that uploads the file to the server through FTP. The drawback with this solution is that it limits your audience to those that have a Java-enabled browser.

make Website in less then 10 Minutes
I've been toying around with AJAX apps and XMLHttpRequest but have wanted to put up a site that loads all of its content asynchronously. If you're like me and you learn best from working with examples you're only 10 minutes away from your first AJAX website. Angus Turnbull of Twinhelix has written an interesting piece of code named, ?HTMLHttpRequest v1.0beta2? and it?s the perfect start to building your own rich client-side web applications that send and retrieve data to/from a server. I have done several examples and tutorials on this subject, but this is one of the most complete I?ve seen to date. This implements both XMLHttpRequest and a custom-written hidden-IFRAME-based transport layer. Therefore, it works in a wider range of browsers, including Opera 7 and IE5/Mac.
Ajax Design Patterns
By now the entire World has heard about AJAX, even those who don?t care about Web-Development have seen the potential of this new technology. Everybody is tired of endless introductions on how cool AJAX is and those endless lists of good examples like Google Suggest, GMail and alike, so I decided to cut a long story short and jump right into the real tutorial. Well yes and no, it is different in being a tutorial on how to design and build a complete site and not just some fancy little details like how to turn caching in AJAX off or how to create a fancy widget. To keep the tutorial readable, and to avoid having to implement low level functionality, I?m using the dojo toolkit, I tried prototype too and really enjoyed working with being a really nice and easy to use Library, but dojo provides much more functionality bundled with it. For both frameworks one thing is true: documentation is scarse, and I spent alot time debugging and reading posts on the newsgroups.
