[Accessibility_sig] JavaScript Checkbox Help Needed

[McMillen, Node]

Thank you.  That does eleminate one message that users will have to click
off.  Our curriculum developers are not computer developers.  They use
Authorware for their products.  I take their products and try to get as
close as I can using html mostly (with a little JavaScript thrown in for the
assesments at the end).  Persons with limited vision tested my program
before I submitted it for DARS approval (which it received).  They had no
problem with the input box for validation.  This was not a problem until it
was discovered that sighted non-employees will be using my programs because
they can't get access to the programs in the agency learning management
system and most don't have the Authorware Player.  

Our curriculum designers are concerned that the sighted non-employees will
have a problem with the validation box and with having to click it off
twice. 

The coding sample you sent will make them a little happier.

Now, if you could just find an Active Server Pages (and VisualBasic) class
that I can take locally . . . .

You have developers that don't know how to fix this? I'd suggest hiring
someone that knows JavaScript.

By your description I assume you've added something like this:

  onclick="alert('uncheck me')"

If thatt's the case, you can switch it to do what you want by changing it
to:

  onclick="if (this.checked) alert('uncheck me')"

However, your accessibility problem comes not from the alerts but from the
fact that you're using checkboxes for validation. I can't say for sure since
I haven't seen it, but you may want to reconsider the user experience aspect
of your web app.
