Re: Help needed with event testing script

Apparently there is a textarea onscroll event bubbling bug in Firefox

I'm trying to check for this bug with the following script and it
*seems* to work. In IE it reports "bubbling" and in Firefox "not
bubbling" but I really have no direct way to confirm the Firefox
results until the bubbling bug is fixed.

Basically the test script assigns an onscroll event handler to a
textarea and then scrolls the textarea down then back up, checking to
see if a the event handler works (assigns the "bubbling" variable a
"true").

If script scrolls then I am not sure Mozilla fires the scroll event, it
should fire it when the user scrolls. At least for a window a quick test
shows that window.scrollTo() doesn't fire the scroll event and even if
onscroll worked for textareas then I don't think the scroll event would
be fired if script manipulates the scroll settings.

OK, with regard to textarea scripts firing onscroll events, why is
there this difference between IE and Firefox?

Also, do you have any suggestions for checking if the textarea onscroll
event in Firefox is working?

Thanks. Mark.

Yes! It demonstrates the bug but provides no work-around.
I was hoping for bug detection without browser version detection but no
luck ... I guess.
