No previous message | Next message →
Hello all:
I would like to know your opinion on a combination of the aria-describedby
labels and aria-hidden that I am using. My idea is to prevent users of
screen readers listen redundant content. I've tested with JAWS 15 and NVAD
2014 in IE 8, IE 11, Chrome 40 and Firefox Safari 3.6.23y with Voiceover on
iOS in August. I have not encountered any problems. Am I missing something?
Would there be any scenario in which this code could be problematic?
The code is:
<label for = "nif"> NIF </ label>
<input type = "text" id = "nif" aria-describedby = "formatonif" />
<p id = "formatonif" aria-hidden = "true"> Do not leave space between
letters and numbers </ p>
Thanks in advance.
Warm regards.

Ricardo,
I am assuming you are just wanting to give screen readers information which is hidden from everyone else. Why do you think you are missing something?

I think the intention is to reduce the repetition of content when the
screen reader is reading through the page. Labels for form controls
will be read twice - once as the label for the control and again when
the screen reader reads the label text.
So long as the label reliably reads in all screen readers, I think
this is probably fine. But I don't think it's necessary. This
repetition is standard, so hiding the label with aria-hidden would be
atypical. Additionally, the repetition is generally not present when
accessing the form because the user will typically be navigating
through the form using the Tab key rather than reading the form from
top to bottom.
I suspect it could also cause some issues if the user were to search
for text on the page. The browser would direct them to the text (not
the labelled control), but the text would be hidden and unread. Yes, a
bit of a stretch, but something to consider whenever you use
aria-hidden on visible content.

Thank you for your response, Susie.
I think I have not explained well. The idea is that when a screen reader
focuses on the field with aria-describedby, it will announce the paragraph
linked content. The paragraph content on the page remains visible to other
users but not again be read by screen reader. In the tests I've done has
worked well, but I wonder if there are some circumstances in which this
programming can be problematic.
Warm regards.

Jared --
Your assertions are correct. We had some Oracle developers trying to do the same thing and there were issues regarding searches. I usually don't do searches as I believe that using the AT package correctly should work, however, what they wanted me to go to was not visible using normal ARIA tricks so I did a search and low and behold, nothing. Now there were probably other issues as well, but I think in this case the use of ARIAHidden is a bit risky.

The reverse would be true in Ricardo's example. The hint would be spoken by
screen readers as they focused on the field, but not as they navigated
through the page outside of the field. The hint would remain visible outside
of the field to everyone else.
I don't believe it's a good technique however. The only way to hear the hint
is by focusing on the field, and then you have to listen to the whole hint
in one go. With aria-hidden set on the hint, it's impossible to explore the
text by word or character using a screen reader.
As speech recognition tools improve ARIA support, I believe this technique
could also prevent a speech user from selecting the hint text. It's possibly
an edge case because it's rare someone would need to cut/paste the hint for
a form field, but worth considering.

Susie, Jared, Don, Léonie,
Thank you very much for your contributions. Clearly it is not good practice.

Well said folks, I agree that this is certainly doable, but not
necessarily a bet practice.
For this particular example it would be ok, but what if the hint said,
say "in case you are unable to log on, call our customer service at 1
800 444 5969, ext. 19827 098 9663888 799 0) (.. for those who have
seen the I.T. Crowd, you probably get the reference).
In other words, if the hint text contains something that the user
needs to memorize or explore, they need to be able to traverse the
hint character by character, copy and paste etc.
Still, I like the thought behind what you did, it is a creative use of
the fact that aria-describedby overrides hidden settings.
You never know when ideas come in handy, so thanks for posting this one.

P.s. Jaws will not read targets of aria-describedby when the verbosity
setting is set to "intermediate" or "advanced", so Jaws users would be
completely unable to see this text in any mode, if they have their
verbosity set that way.

Thanks, Bikir, for his contribution, further clarifies the problems that
this use might suppose.

Ricardo, it's great that you're aware of how annoying and
time-consuming repetition can be, and that you're using ARIA to solve
real-world problems. I think that ARIA is the best thing that's
happened to accessibility in a very long while.
I'd agree with what the others have said - but keep coming up with
ideas like this and running them past us. I've learned a few things
just by reading this thread, and perhaps others have too.
Best, Lynn

Hi, Lynn,
I also think that Aria is a breakthrough in accessibility and think we
should explore the possibilities offered to enhance the user experience. I
appreciate and learn from the contributions in this list, so we can consult
our ideas before creating a page that creates problems for users.
Best regards.

Hi, Lucy:
As you may have noticed, my English is very limited. So, I have not been
able to understand the content of your comment. Could you make an accessible
version for people unfamiliar with your language? [smile]
Thanks in advance and best regards.
