22168 - [EVENTTARG] javascript: URL not working (inside absolutely positioned DIV??)

Status: VERIFIED DUPLICATE of bug 20051

(Core :: DOM: Core & HTML, defect, P3)

Description

[John Morrison]

This bug report is a spinoff from bug #21013 for http://www.espn.com/;
There are several problems with this page; See also bug #14030, for
the same page which covers a problem with paragraph spacing.

This bug report specifically concerns the javascript tab panel in the
center of the page at http://www.espn.com) (http://espn.go.com/)

Summary: javascript: URL not working (inside absolutely positioned DIV??)

Overview Description:

  On the ESPN page, in the center section, is a panel of tabs with news
  stories. With Mozilla 1999121708 WinNT, when you mouseover the javascript:
  URL on each tab, the event is not recognized, no is onclick().

  The javascript: URL won't work if fired, since it uses layers. However, I
  have a test case with some quick and dirty changes that (1) works with W3C
  DOM, and (2) provides two alternate test buttons that do fire the mouseover
  and onclick events.  (I will attach the test case).

Steps to Reproduce:
1) Open the first attachment to this bug report.
2) When loaded, mouseover the tabs 'NFL' and 'M College BB' in th center of
   the page.
3) Notice that the cursor does not change, no does onclick fire.
4) Now mouse over the 'NFL' and 'M College BB' tabs in the top left.
5) Try clicking 'M College BB' and then 'NFL'; panels and tabs in the center
   will change

Actual Results:   javascript: URL fires onmouseover and onclick events
Expected Results: events did not fire (except when outside the abs. pos. DIV)

Build Date & Platform Bug Found: 199121708 WinNT

Additional Builds and Platforms Tested On: none others tested

I just noticed that many of the <A HREF='...'> on the www.espn.com page do not
behave as links (onmouseover,onclick). so it's not limited javascript: URLs.
(which may also point away from DOM and into events/frames.

The problem is that events seem to be delivered to views that correspond to
positioned content that isn't visible (via CSS). In this example, the events are
delivered to the images in the DIVs with ID=topTab<foo>H, even if the DIV has a
CSS visibility value of hidden. Reassigning to joki as per our conversation.
