JavaScript and Accessibility

- Creating Accessible JavaScript
Series of helpful tutorials on creating accessible JavaSCript. Topics include: Overview of Creating Accessible Javascript, JavaScript Event Handlers, Other Issues, JavaScript Alternatives, Accessible JavaScript Summary. [Article/tutorial by WebAIM.] - JavaScript Interaction Must be Input Device Independent
Helpful reminders and information, along with often overlooked common accessibility problems, such as allowing for users who don't or can't use a mouse. Drag-and-drop functionality,onClick
event handlers are discussed, along with helpful examples and solutions. [Article/tutorial dated 08/21/2007, by Roger Johansson, for 456 Berea Street.] - Too much accessibility - multiple JavaScript event handlers
Helpful information about browser differences with JavaScript event handlers. “if two or more event handlers, designed to perform the same task are used, the effect can be the opposite of the one you intended. The most common problem is whereonClick
is used, and authors, believing that this is a mouse dependent event handler, will add anonKeypress
, or similar to make sure that keyboard and switch users aren't left out. The problem here is caused by the belief thatonClick
is always mouse dependent. If the event is attached to a link or form control, onClick is device independent. In Internet Explorer there is no effect whenonClick
andonKeypress
are used together; the second handler is ignored. No surprise there then. However in Mozilla Firefox and Opera, the web author is taken at his word, and usingonClick
withonKeypress
will activate the link or button, when all the user is trying to do is navigate over and passed it.” Editor note: While the author doesn't provide a solution to this problem, one possibility that I've used successfully is a simple PHP browser sniff for Firefox and Opera to exclude them from seeing theonKeypress
event. The specific problem I had was with a show/hide script for footer navigation subcategories. Tabbing onto the “Show/hide” link would end up creating a stuck focus (not allowing tabbing forward or back but would instead only show or hide the navigation subcategories). A simple PHP browser sniff for Firefox and Opera fixed the problem. [Article/tutorial dated 11/17/2006, by Bim Egan, for Web Access Centre Blog, RNIB (Royal National Institute of Blind People).] - You cannot Rely on JavaScript being Available. Period.
JavaScript problems that block users from accessing 3 highly popular sites - Blogger, Bloglines, and ma.gnolia - along with describing the problems and what can be done to avoid them. It's not just about JavaScript being disabled but a lot between, along with a 'submit' button that requires JavaScript to function, and a JavaScript library that triggers a security setting for firewalls. As Roger points out, he's all for using JavaScript, but it must be used “responsibly and always in the spirit of progressive enhancement or Hijax.” [Article/tutorial dated 08/21/2007, by Roger Johansson, for 456 Berea Street.]

Learn how to create universally accessible Web sites based on best practice approaches, including how to create semantic, accessible HTML, audio, video, Flash, multimedia, PDFs, how to use progressive enhancement for the widest accessibility, and much more.
From the author about his book:
When I say “creating content for everyone”, that's exactly what I mean. The techniques that I cover in the book are targeted toward serving the audience of users with disabilities (and this is an important growing audience), but that's not all they're good for. If you want to reach audiences that use cell phones, PDAs, game consoles, or other “alternative” browsers, you need the same eye toward semantics, alternate access paths, and progressive enhancement that assistive technologies rely on.
The publisher's description:
It's not a one-browser web anymore. You need to reach audiences that use cell phones, PDAs, game consoles, or other “alternative” browsers, as well as users with disabilities. Legal requirements for assistive technologies as well as a wide array of new browsing experiences means you need to concentrate on semantics, alternate access paths, and progressive enhancement.
Give your audience the power to interact with your content on their own terms. It's the right thing to do, and with a $100 billion a year market for accessible content, new laws and new technologies, you can't afford to ignore accessibility.
With this book, you'll learn basic principles and techniques for developing accessible HTML, audio, video, and multimedia content. In addition, you will understand how to apply the principles you learn in this book to new technologies when they emerge.
You'll learn how to:
- Use best practices of accessibility to develop accessible web content
- Build testing into projects to improve results and reduce costs
- Create high quality alternative representations for your audience
- Add accessibility features to external media like PDF and Flash
- Negotiate the terrain of accessibility standards
- Apply principles of accessiblity to new technologies as they emerge

- Maximum Accessibility: Making Your Web Site More Usable for Everyone
By John M. Slatin, Sharron Rush. Published by Addison-Wesley Professional, September 20, 2002. Rave reviews everywhere. From the publisher:
Maximum Accessibility is a comprehensive resource for creating Web sites that comply with new U.S. accessibility standards and conform to the World Wide Web Consortium's Web Content Accessibility Guidelines 1.0. This book offers an overview of key issues, discusses the standards in depth, and presents practical design techniques, up-to-date technologies, and testing methods to implement these standards for maximum accessibility. You will learn how to:
- Write effective text equivalents for images and audio files
- Caption soundtracks and describe the action of videos and animation
- Set up data and layout tables that make sense to the ear and eye
- Design Web forms that people can interact with via the keyboard and other input devices
- Label forms so that people who use talking browsers can give the right information at the right time
- Make scripts accessible to people who don't use a mouse
- Create simple PDF files that are accessible to people with disabilities
- Use cascading style sheets to make your thoroughly accessible pages look great
Throughout the book, case studies illustrate how inadvertent accessibility barriers on major Web sites affect the ability of people with disabilities to locate information, participate in e-commerce, and explore the richness of the Web. These case studies demonstrate how certain design features can make access much harder, and how other features can greatly ease the use of a page or site.
Most of all, this leading-edge guide reveals that a little extra design consideration up front can help you create a site that is not only a pleasure for people with disabilities, but attractive and pleasing for all interested users. In short, Maximum Accessibility shows why good design is accessible design.
