- Creating a MySQL connection with PHP/AJAX
The purpose of this article is to demonstrate how the XMLHttpRequest object works within php and the advantages of using it. This tutorial will be the first in a series of articles leading to the development of a fully functional dynamic web events
application. AJAX is a fancy technique for creating websites that gather information from servers without having to refresh themselves. I could get into the
- Getting Started with Ajax
The DOM plays into Ajax in a number of ways. How you use the DOM depends a good deal on how you handle the content returned from the server. You can treat the content as simple text using the
response Text property of the server response, or you can treat it as XML using responseXML.
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.
Ajax: Introduction to Ajax
- from an overview to a detailed look -- to make extremely efficient Web development an easy reality. He also unveils the central concepts of Ajax, including the XMLHttpRequest object.
Five years ago, if you didn't know XML, you were the ugly duckling whom nobody talked to. Eighteen months ago, Ruby came into the limelight and programmers who didn't know what was going on with Ruby weren't welcome at the water cooler. Today, if you want to get into the latest technology rage, Ajax is where it's at.
These are both familiar; desktop applications usually come on a CD and install completely on your computer. They might use the Internet to download updates, but the code that runs these applications resides on your desktop. Web applications -- and there's no surprise here -- run on a Web server somewhere and you access the application with your Web browser.

The benefit to end users is that they don't have to type as much and they don't have to wait as long. For example, having the user's city and state show up in a webpage automatically after the ZIP code has been typed in is a big time saver.

In contrast to other solutions AjaxAnywhere is not component-oriented. You will not find here yet another AutoComplete
component. Simply separate your web page into multiple zones, and use AjaxAnywhere to refresh only those zones that needs to be
* Easy to integrate. AjaxAnywhere does not require changing the underlying application code.
* Lower technical risk. Switch whenever you need between AJAX and traditional behaviour of your web application. Your application can
also support both behaviors.

- Very Dynamic Web Interfaces
The user requests a page from the server, which is built and delivered to the browser. This page includes an HTML form element for capturing data from the user. Once the user posts their input back to the server, the next page can be built and served based on the input, and so the process continues. This is largely dictated by the nature of HTTP and differs from the traditional desktop application model of an interface which is inherently connected to the application layer.

The two features in question are that you can:
* Make requests to the server without reloading the page
* Parse and work with XML documents

Internet Explorer on Windows, Safari on Mac OS-X, Mozilla on all platforms, Konqueror in
KDE, Ice Browser on Java, and Opera on all platforms including Symbian provide a method for client side
. The Object makes many things easier and neater than they other would be, and introduces some things that were otherwise impossible such as HEAD requests to see when a resource was last modified, or to see if it even exists. It makes your scripting options more flexible allowing for POST requests without having the page change, and opens up the possibility of using PUT, DELETE etc. These methods are increasingly used to provide richer Web Applications like G-Mail that use lower bandwidth and offer snappier user interaction.
Getting to a semi-usable point with my system took me about a week of part-time digging, and coding.
This was done on evenings, and only when I could get an hour here and there to work on it.
My goal was three-fold.
1. The ability to have PHP output discrete portions of a page (a major part of AJAX)
2. To be able to take those different pieces and have a simple way to update the html page
3. To be able to submit form information to a script and have the results returned as in point 1
- AJAX: Instant Tutorial
Simply put, AJAX allows you to make a call to an http server (typically an RSS feed or a webpage), get it’s content and load them into your existing page without having to refresh the whole page. This means that services like email don’t have to reload the whole page everytime you click a message, saving on bandwidth (loading the header/footer all over again) and making things more efficient.
- A Simpler Ajax Path
I began working with web applications back in the bad old days, when making an application behave like a desktop app meant wrestling with byzantine table-based layouts nested five and six levels deep, and horrid, hackish frame sets within frame sets within frame sets. Those were the days.
Things have steadily improved for web developers with the advent of standards-compliant browsers, CSS, DHTML, and the DOM. Pervasive broadband access has made web apps feel a lot snappier. Now something called the XMLHttpRequest object makes it even easier to develop full-blown,
super interactive applications to deploy in the browser.
- The Hows and Whys of Degradable Ajax
And so we’ve developed some solid strategies to help us use Ajax in our apps without having to worry if they’re essential or not to the application. After some heavy experimenting, we’ve developed a method for making web pages work regardless of the user’s browser settings. While other sites have implemented their own versions of degradable Ajax, we found the lack of documentation on the subject discouraging. And so it is with great pleasure that we present to you the
Particle tree method of degradable Ajax.
- Remote Scripting with AJAX
This two-part series of articles covers remote scripting using the AJAX XMLHttpRequest protocol. Part one walks through an example application that demonstrates how to implement the protocol, while part two will show how to create a usable interface.
To begin, download the code archive, which contains all of the files you'll need to create the working examples presented here and for the upcoming second part of this series.
However, remote scripting and seamless applications bring with them a host of problems from the desktop application design realm, making those same issues possible on the Web.

- An Introduction To Ajax
As J2EE developers, it seems we are constantly focused on "backend mechanics." Often, we forget that the main success of J2EE has been around the Web application; people love developing applications that utilize the Web for many reasons, but mainly because the ease of deployment allows a site to have millions of users with minimal cost. Unfortunately, over the years we have invested too much time in the back end and not enough time in making our Web user interfaces natural and responsive to our users.
- Developing AJAX Applications the Easy Way
AJAX is the buzzword of the moment among web developers, so much so that you could be sick of introductions to AJAX by now (if that's the case, skip down to "The Chat Web Page"). AJAX is a technology that is hotly debated from many angles, but it has stuck because it encapsulates something that is new from a user's perspective. The functionally that is newly available to all web users is "in-page replacement": the ability for a web page to change using data from a web server without totally redrawing itself. This functionality has been around in Mozilla and Internet Explorer for a while, but it is only recently that Safari and Konqueror users have been able to join in.
- Ajax on Rails
In a few short months, Ajax has moved from an obscure and rarely used technology to the hottest thing since sliced bread. This article introduces the incredibly easy-to-use Ajax support that is part of the Ruby on Rails web application framework. This is not a step-by-step tutorial, and I assume that you know a little bit about how to organize and construct a Rails web application. If you need a quick refresher, check out Rolling with Ruby on Rails, Part 1 and Part 2.
- Ajax Mistakes
Ajax is also a dangerous technology for web developers, its power introduces a huge amount of UI problems as well as server side state problems and server load problems. I’ve compiled a list of the many mistakes developers using Ajax often make.
Sure Ajax is cool, and developers love to play with cool technology, but Ajax is a tool not a toy. A lot of the new Ajax applications are really just little toys, not developed for any real purpose, just experiments in what Ajax can do or trying to fit Ajax somewhere where it isn’t needed. Toys might be fun for a little while, but toys are not useful
applications. The back button is a great feature of standard web site user interfaces. Unfortunately, the back button doesn’t mesh very well with
