24118 - innerWidth property inconsistencies

Status: VERIFIED DUPLICATE of bug 9606

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

Description

[Hrunting Johnson]

The innerWidth property is supposed to give the interior dimensions of the
window or frame object (as I understand it).  This shouldn't include
scrollbars, and indeed, Netscape 4.7's implementation ignores the scrollbars
when calculating this value (it might be irrelevant; Netscape renders the
scrollbar space no matter what, it seems).  In Mozilla M12, when accessing this
value, the return is the pixel width of the window including scrollbars, even
though page contents are never rendered under the scrollbar (ie. it is a non-
viewable area).  Since scrollbars aren't always included in the web page's
rendering, this can lead to inconsistencies across a site.  Of course, there's
no way to determine scrollbar width or even presence (it seems, although it can
be set in some instances), so this inconsistency can lead to problems.  I'd
recommend that the width of the scrollbar be removed from the innerWidth
property if the scrollbar is visible.

For reference, please visit http://studio.home.fastolfe.net/.  Without
scrollbars, the two lines in the div objects line up.  Other pages on the site
(try clicking on the 'd' link) which are longer and create scrollbars don't
line up as they should.

I apologize if this bug has already been reported.  The search script
repeatedly returned a server error when I tried to search for information on
this bug.

Please feel free to e-mail with any questions.
