No previous message | Next message →

Hello,
I am trying to learn about ARIA, though I haven't actually had any chance to implement it yet. While I generally understand the concepts, the syntax has me stymied. In particular the use of the tag in ways I have never seen it used before, as shown below in the example of a progress bar widget:

<div id="percent-loaded" role="progressbar" aria-valuenow="75" aria-valuemin="0" aria-valuemax="100" />

Can someone please explain this use of the tag or steer me towards a tutorial that deals with, or includes a discussion of syntax?

Thank you,

You're confused because that example is very much incorrect. Remove all of
the span tags and you'll have something that is valid:

<div id="percent-loaded" role="progressbar" aria-valuenow="75"
aria-valuemin="0" aria-valuemax="100" />

Where did you find that example?

I'm not sure where you are getting this syntax but my bet is it was copied
from a web page code highlighter. The author must have accidentally
included the spans. If you remove all of the open and close span tags, then
you have a plain old DIV tag with a bunch of attributes. (The DIV tag is
internally closed, which you don't see much, but I believe is valid.)

Yup, it's stray syntax highlighting code - the SPANs were in the underlying HTML, possibly left over from a cut-and-paste from elsewhere, then the syntax highlighting code in the mozilla page was turning them into visible text. I've edited the page to remove these stray tags, so if you reload it, you should see the correct syntax now.
