The accessibility community is understandably concerned about the accessibility of client-side scripting, in particular using Asynchronous JavaScript and XML (Ajax) to produce Rich Internet Applications. Steve Faulkner of Vision Australia and founder member of the Web Accessibility Tools Consortium (WAT-C) and myself on behalf of The Paciello Group (TPG) have collaborated in an effort to come up with techniques to make Ajax and other client-side scripting techniques accessible to assistive technology. The Web Accessibility Initiative's Protocols and Formats working group directly address the issue of making rich Internet applications accessible, and we borrow some of their concepts to investigate methods of ensuring that Ajax applications work with leading assistive technology products. The bad news is that it isn't possible to make Ajax work in every known assistive technology, in the same way that it isn't possible to get Ajax to work with older browsers, but we explain the fundamental issues; how to inform users of assistive technology that a change has taken place, and how they can interact with the content. To illustrate our findings, we summarise the behaviour of popular screen readers.

JavaScript is a scripting language used to make HTML documents more dynamic. Oftentimes, user actions trigger scripts which modify the page. Users may not realize a page has changed or may not be ready for the page to change when it does. On the other hand, if done well, JavaScript can enhance the accessibility of pages by allowing users to customize them to their needs.

In these notes, I summarize my presentation of original research and testing of an Ajax application (Basecamp) with users of screen readers and other adaptive technologies.

With the advent of mass-hype for building AJAX solutions, I find it necessary to shed some light of AJAX and JavaScript implementations and how they relate to and affect accessibility, and to explain how they can both co-exist; that one doesn’t exclude the other.

We've all heard a great deal of buzz about AJAX in the last few months, and with this talk has come a legion of articles, tips, presentations and practical APIs designed to explore the possibilities and try to arrive at best-practice techniques. But, for all of the excitement and hype, still very little has been said on the subject of AJAX and accessibility.

Recently, there has been a lot of interest in using AJAX (the technology, not the detergent) when building web applications. I have a feeling that javascript and the XMLHttpRequest object will be the Next Big Thing ™. Let’s have a look at how usability and accessibility of AJAX forms can be improved. In this article we will have a look at the implications for accessibility and usability when using Javascript to dynamically update a web page. I will also show how you can increase accessibility for AJAX-based forms.

Asynchronous JavaScript and XML (AJAX) is a hot new technology on the Internet that allows the incremental update of portions of a Web page without reloading the entire page. This has great performance benefits and provides a medium for developing rich Internet applications. Accessibility concerns have arisen with the increased use of JavaScript and AJAX on the Web. This article introduces AJAX and discusses some of the accessibility issues and best practices.

Sometimes we have to use pop-ups — so we might as well do them right. This article will show you how to make them more accessible and reliable while simplifying their implementation.

Ajax et l'ergonomie sont-ils conciliables ? L'accessibilité est un problème majeur dans l'utilisation d'Ajax. Comment tirer profit de cette technique de conception qui contribue fortement à enrichir l'expérience utilisateur ? (28/06/2006)

Si on veut utiliser Ajax sur un site web, comme sur un blog, il faut faire attention à l'utiliser correctement. En effet, mal utilisé, un site peu devenir totalement inaccessible.
