[Nfb-web] accessible ajax

[Peter Donahue]

Good afternoon again folks,

    I have encountered Web sites which implement AJAX for displaying
particular content and allowing one to update portions of Web pages without
needing to refresh the entire page every time such up-dates are done. This
is pretty cool stuff when we can learn how to implement AJAX on our
affiliate Web sites and ensure their accessibility. The information below
will help us do that.

You should probably be aware of the work IBM, Mozilla, W3C, Opera and
others are doing in the area of AJAX and DHTML accessibility.

It's pretty exciting stuff -- making Web 2.0 accessibility possible. The
major areas are keyboard accessibility, screen reader support of
JavaScript widgets, making live changes on a page accessible, drag and
drop, and support for landmarks in a page.

Here's a FAQ about it -- don't be confused about the fact that it
discusses HTML 5 (which doesn't exist yet). I wrote the FAQ to
facilitate communication with the HTML 5 standards group:
http://developer.mozilla.org/en/docs/ARIA:_Accessible_Rich_Internet_Applications/Relationship_to_HTML_FAQ

The easiest way to take advantage of it at this point would be to use
Dojo, because of all the work that has been going on putting ARIA
support into Dojo.  You can also use ARIA directly. In addition, we'd
love to get help from more developers to put ARIA support into other
open source Javascript toolkits, such that users of Scriptaculous,
JQuery, etc. would get accessibility for free.
