Hi all,

Apologies if this topic has already been discussed on-list. Because it's a rather last-minute issue, I haven't had time to dig through the archives.

We have a Web application here that uses some AJAX in at least one Web form. I can't link to the Web app because it's password-protected and behind our firewall, sorry. In this form, the user selects an item, which causes some new form fields to appear for that selected item. As a JAWS user, when I select one of these items, I get no feedback whatsoever that anything has occurred at all.

The developer is currently trying some of the suggestions demonstrated on the Juicy Studios site. While they work, they require me to turn off the JAWS virtual PC cursor in order to hear the notification that the action has taken place. To me, while this is technically doable, it requires extra steps that the average JAWS user here isn't going to wish to bother with. Not only that, I don't know how or if this works with other screen readers.

Are there any better solutions to this that I can suggest to the developer, or is the best solution to find a non-AJAX method for performing these functions? Whatever we go with has to be able to be considered Section 508 compliant, obviously.

Thanks much.

Courtney

Hi Courtney,

An ARIA alert could possibly be used. It is supported by most major screen reading software, but I am not sure how each software treats an ARIA alert, so a non-AJAX solution may be best.

Aria Alert : http://www.w3.org/TR/2010/WD-wai-aria-20100916/roles#alert

More info: http://www.w3.org/TR/wai-aria-practices/#docmgt

The entire WAI-ARIA Authoring Practices document is a good read. Hope this helps.

Can you try a forced screen refresh with JAWS key + escape and see if that
does anything. I have encountered some pages like this and the screen
refresh worked in some cases.

You might also want to try this thing as an isolated case first to get the
bugs out - this is one of those situations where a model would serve your
interests by insuring that you are working it out on the isolated prototype
before you trying adding it into the rest of the page.

Incidentally, is this form content being generated by XML/XSLT? Just
curious.

I could be wrong but dropping it into the forms mode should do the same

I know that some people are going to think this is a terrible way to deal
with the problem - but I think it will work.

Push the JAWS screen reader into forms mode. It is only a step away from
application mode and "Virtual Cursor Off" and you may get the results that
you are looking for.

One way to do this is to drop the focus (after clicking the button) onto a
text field. Considering that you are adding form data, this might be a
viable alternative. I strongly suspect that you will get the behaviors you
described.

If not, oh well - it was worth a shot, right?

Hi,

I spoke to the developer, she doesn't think there's any XML or XSLT involved.

I'm going to send along your suggestions to her as she's not currently on the WEBAIM list.

Thanks!

When you say you get no feedback, do you mean there is no annunciation
by JAWS, or the buffer does not update to show the new controls?

Can you find controls by manually tabbing or arrowing?

There are potentially different solutions to either scenario.

Hi Tony,

The new controls are shown, but JAWS does not announce that anything has changed.

Does it need to? JAWS users don't always have to be informed of
content or interface updates that occur in other areas of the page,
especially if those content updates are easily found simply by
navigating or reading forward. It sounds in this case that you may be
trying to find a solution to a problem that doesn't exist. In other
words, the user may not care that an update has occurred, so long as
the updated content is accessible when they get to it.

Hi courtney,
sounds like a job for ARIA live regions;

Good. There can be a loss of synch that can happen between JAWS and IE
when the XML/XSLT is being used because JAWS uses both MSAA and screen
scraping to handle its DOM content. The MSAA sends it at a different time
and they can end up going boom! in some cases.

Have fun,

Courtney,

My question then is more related to focus and user behavior. If the
new controls appear after a blur, you may have to do some JS focus
redirection, certainly if they are appearing outside of the
immediately contiguous tab order this is the case. If however, they
are appearing in the tab order immediately following the control, and
fast enough to be included when the user presses TAB, an alert may not
be necessary.

I'd have to have a better idea of the user behavior to answer it
better, but focus redirection may be a bigger help than an alert.

Hi,

Hmmm.
I agree with you on the content that shows up further down the page.
I guess, for me, it's a question of how much further down the page. In this case, the new content starts with the very next form field.
Admittedly, this is my first experience with AJAX and JAWS behaviors, at least here at work. I'm not used to not receiving notification that hitting Enter on a control has performed any action. So I may be using too much of my personal preference to determine what's right or wrong, instead of what officialy constitutes accessibility or inaccessibility. (grins)
That's why I love learning so much from this list.

Courtney

Does it need to? JAWS users don't always have to be informed of content or interface updates that occur in other areas of the page, especially if those content updates are easily found simply by navigating or reading forward. It sounds in this case that you may be trying to find a solution to a problem that doesn't exist. In other words, the user may not care that an update has occurred, so long as the updated content is accessible when they get to it.
