Trying to change style properties using
document.getElementById(id).style.setProperty('z-index', 1, '') doesn't work.
Nothing changes. I've also tried by assigning to style.zIndex, and others, such
as backgroundColor, but nothing changes.

Here's a test case that doesn't work for me:
<html>
<head>
<SCRIPT>
function raise(obj)
{
var style = obj.style;
style.setProperty('z-index', 1 + Number(style.zIndex), '');
dump('z-index = ' + style.getPropertyValue('z-index') + '\r');
}
</SCRIPT>
</head>
<body bgcolor="#FFFFFF" text="#000000">
<form>
<div id="myDiv1"
onMouseOver="raise(document.getElementById('myDiv1'))"
style="position:absolute;z-index:1;top:10px;left:10px;background-color:gray;
width:100px;height:75px;overflow:scroll">
Hello<BR>Hello<BR>Hello<BR>Hello<BR>Hello<BR>
</div>
<div id="myDiv2"
onMouseOver="raise(document.getElementById('myDiv2'))"
style="position:absolute;z-index:0;top:40px;left:40px;background-color:blue;
width:100px;height:75px;overflow:scroll">
Hello<BR>Hello<BR>Hello<BR>Hello<BR>Hello<BR>
</div>
</form>
</body>
</html>

In an attempt to get my bug list in order again, marking all the bugs I have
currently as ASSIGNED.

Migrating from {css2} to css2 keyword. The {css1}, {css2}, {css3} and {css-moz}
radars should now be considered deprecated in favour of keywords.
I am *really* sorry about the spam...

This is only an issue if the DIV is scrollable. In that case, z-index is
ignored, whether its in the original inline STYLE attribute or set later via the
DOM. I'm attaching two test cases - one which works correctly (had to make some
modifications to the original test) without overflow and the same test with
overflow. Passing along to Eric Vaughn.

nominating for beta2, we're not sure how common this is & would like PDT to
make the call.

PDT needs info on how common this is to triage for beta2.

This is yet another absolute positioning bug with gfxscrollbars. Which I believe
is already [beta2+]. Hopefully they are all the same root problem.
|
||
Comment 12•25 years ago
|
||
I don't think this is common within content, so it can be deferred for beta3
from that standpoint. I don't understand what the other gfxscrollbars issues
are or what the relationship to them would be. But those other bugs haven't been
marked as depending on this.

There's something a little bit strange going on here; it would be good to know
if the behaviour is correct.
When you move from the raised square to the unraised one, the unraised one
doesn't raise unless you are _not_ hovering over the text. This is in both
testcases.
Is that right?

I think that behaviour is correct. The Javascript tests "if (event.target ==
this)"; when you mouse over the text, event.target will be referring to the text
node, not the DIV node.
This bug is now fixed.

With 2001040120 on Windows 2000, the scrollbar on the gray div of the test case
with overflow displays two thumbs when I scroll down. (With the Classic skin, at
least. Haven't tried others.)
