Chat live content issues

[Andre Polykanine]

Hi everyone,
Here is my question.
There is a live chat.
The main content is updated in a div set up like this:
<div id="content" role="main" aria-live="polite">
First of all we tried to re-draw it totally on each AJAX request:
// It's jQuery
$("#content").html(response);
Then (logically!) JAWS 14 - what I'm working with - began reading all
the chat content each 5 seconds (that's our update interval).
Then we realized that it's not too optimal to do so.
And we replaced it with a prepend:
$("#content").prepend(response);
response being, for sure, a server response with new chat content.
Now JAWS doesn't read automatically anything.
My question is: why is that? What are we doing wrong?
Thanks!

Andre, what browser are you testing with? The behavior is usually more sporadic with Interoet Explorer.

The simplest way to do this, is to use unobtrusive announcement.

There is a jQuery script available for doing this at
http://whatsock.com/modules/aria_announce.js

So you can remove the aria-live=polite from the main div, which will cause
all of that content to be announced, and simply do the following instead.

When the new content loads, pass the DOM node for the last message to the
'announce' function, and set noRepeat to true.

announce(lastMsgNode, null, true);

This has been tested using JAWS11+> in IE8 and 9, Firefox, and Chrome;
using NVDA in IE 8 and 9, Firefox, and Chrome,
and using Voiceover in Mac and iOS Safari.

This is demonstrated at

Hi Bryan,
I just ran your example and ended up with double announcement, plus the echo back of the original message. Was this your experience as well?
This is with VoiceOver and Safari on Mountain Lion.

That is strange, I haven't seen that. Are there any other ARIA roles within
the markup?

Hello Victor,

I'm working with IE9, so the solution should work there, at least).
Will try Bryan's implementation.
