Dynamic image maps broken uder IE8-Beta? (with sample page)

Are dynamic image maps broken under IE8-Beta or am I missing something
obvious?



Tested and found working under IE6, IE7, Fx 2, Fx 3 (Beta)

Is this something I should worry about, or should I delay my panic until
IE8 final comes out?

What is the difference between a dynamic image map and one that is not
dynamic?

In this context, I was using "dynamic" in the sense of "dynamic HTML."

Under IE8, if I have an AREA defined in my HTML then I can attach an
onclick handler, and it will work.

If I create an AREA tag and append it to my MAP structure, then the
attached onclick handler will do nothing.

On every other browser that I have tested (including IE5.5, 6 and 7, Fx2,
Opera 9, Safari and Konq) both methods have a functional onclick handler.

JavaScript is heavily broken in IE8. Try visiting Google Maps or even some
of Microsoft's own sites like Live Maps. It will be fixed before the
release, it would be suicide for them not to.

Thanks for the heads up.

I've only used IE8 in a [slow] virtual machine here, so its been too
painful to test on any other site than my own.

I'll put it on the back burner and tell the folks who are using IE8 that
its a) broken and b) their fault for using a beta with no other plan.
They can drop back to the IE7 engine if they need.

This will work in IE 8 beta 1 with DOM 2 HTML methods instead of using
setAttribute. I have made a few changes from your testpage though:






(...)

height=3D"300" alt=3D"Image download support must be enabled for this
test" usemap=3D"#mymap">

, not creating another

.
- I also renamed several objects: function names, image filenames,
etc.
- I removed setAttribute everywhere and used instead DOM 2 HTML
methods:
http://www.w3.org/TR/DOM-Level-2-HTML/html.html#ID-26019118
- style=3D"cursor: pointer;" removed
- event replaced by evt; it could be removed entirely
- ismap removed

A few more aspects of the testpage could still be improved: like
testing support for createElement and getElementById before calling
them.

*nods* I was just trying to keep it simple there.

That is the magic. I have no idea why that didn't cross my mind. So I
guess I was doing something stupid.

I'll do a bit of reading, try to figure out why you would have removed
'ismap'.

Of course, of course!

Those tests should be in my production code. I'll double check I rolled
those changes out.

A dozen thanks.

I'm wearing a dozen hats here at work, but I've got your message saved
for the next time I wear my webdev one.
