161570 - border collapse property may only be set once

Status: VERIFIED WORKSFORME

(Core Graveyard :: GFX, defect)

Description

[Will Holcomb]

This piece of javascript will only work if the table is initially set to
collapse and then it will only work once.

function toggleBorderCollapse() {
  var table = document.getElementsByTagName("table")[0];
  table.style.borderCollapse =
    table.style.borderCollapse == "separate" ? "collapse" : "separate";
  window.status = "Set border collapse to: " + table.style.borderCollapse;
}

This was a problem a while back, but has been fixed for a number of months now...

Will, please reopen if you are seeing this with a current (1.1beta) build.

Attachment: A document with a script of the sort described in the initial report

This was intially a bug test for the border-collapse property, but the
javascript to test didn't work correctly, and it became a bug report on setting
the borderCollapse style rule.

I am reporting this from mozilla 1.1b 2002072104

[Boris Zbarsky [:bzbarsky]]

Hmm...  I don't think anything really major has changed in this area since
1.1beta, but I can't reproduce this....

Comment 8

[Boris Zbarsky [:bzbarsky]]

From some mails:

Will (paraphrased):

"In a current build it almost works.  I see some flickering, but it does not
paint the border."

Me:

I did some testing and I see the problem in your bug report with build
2002-07-23-08.  It works fine for me with build 2002-07-23-21.  Looks
like bug 158230 may have been responsible for fixing this... (at least
to the point where the problem is now a painting one).

The missing border is already reported in bug 161566 (assigned to HTMLTables).
So, is this bug about the "flickering"?

Comment 10

[Will Holcomb]

This bug is about the borderCollapse style being set and only changing the first
time that it is set. The expected behavior is for each click to toggle the style
and for the table back and forth. (Well, each click does toggle the style, the
expected behavior is for each change of the style to cause the page to be
displayed with that appearance.)

It has been reported that in linux this happens. In NT and 2000 when I click it
changes the first time, but after that only flickers a bit. The table does not
change.

Why noone else seems to experience this is beyond me. I can't imagine I am
clicking poorly. =)

Thanks for the info Will, but if you read the comments we think this has been
fixed already (Boris tracked it down to 2002-07-23). Your build is older.
Since this part of the bug is "WORKSFORME" I was wondering if there were other
problems that would justify this bug still being open.

Will, could you download the latest build from 
ftp://ftp.mozilla.org/pub/mozilla/nightly/latest/
and see if this solves the problems reported in this bug? Thanks.

Comment 13

[Will Holcomb]

The nightly build fixes it

Comment 14

[Mats Palmgren (inactive)]

OK, thanks.

Verified wfm.
