Subject: WAI ARIA help.. select boxes that are populated via AJAX
No previous message | Next message →
Hi,
I am still a newbie to WAI-ARIA and wondering if anyone can help me
with the following:
We are updating our search functionality on our live site and will be
calling data via AJAX. in the following way:
When a user comes to a search page, there will be two or three select
boxes with only the first select input be enabled.
1. The user picks an entry in the first select box.
2. This enables the second box and populates it via AJAX based on the
selection in the first box.
3. The third box is Optional, but it will be populated based on the
first and second selection via AJAX
I understand from the backend developers, they are going use an
onChange event to make the changes
For accessibility, do we need to add WAI-ARIA live regions to the
<select input?
I found this online. Would this be an answer for what I need?

Can someone explain or point me to good references with good set of
demos or samples?
Thank you
Nancy Johnson

I don't think you need any ARIA markup for this. We have tested this type of
functionality with screen reader users several times and they have always
been able to understand what is happening. The article you mentioned
acknowledges that it is necessary for the user to have this understanding.
If they don't, then the ARIA won't help them. If they do, our experience
suggests that they don't need the ARIA.

What about adding a small hidden text before the first listbox saying
"when you select an option from this box, the next box (which you can
reach by the tab key) will be populated automatically with values).
The problem, to me, is when these things happen without the user
expecting or checking for them, but if they are aware of it, onChange
events do not have to be bad at all.

Do NOT added aria-live to the combobox.
Here are examples of aria enabled comboboxes.

Hi Nancy,
Welcome to the world of WAI - ARIA. If my understanding is correct, your
second select box and so on would enable, only when user make a choice for
first or prior select box. In this scenario, I also understand, the select
box will enable only user makes selection in first select box and use tab
key to the next box. In that case, I don't think, ARIA would really add
value to this as long you are using corrent semantics and structure.
Sorry for the delay, btw,
