131029 - innerWidth is incorrect when a scrollbar is present

Status: RESOLVED DUPLICATE of bug 48634

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

Description

[Dave Itter]

From Bugzilla Helper:

When you grab the innerWidth in javascript, the value is correct, as long as you
don't have a scrollbar present. If the page is longer, and the scrollbar
appears, the innerWidth is still reported as the size of the entire browser.

I worked around it by comparing the document.body.offsetHeight to the
innerHeight to see if the scrollbar would be present, and changed the innerWidth
according to that.

Reproducible: Always
Steps to Reproduce:
1.Create a page that displays the innerWidth in javascript without scrollbars
2.Make the page longer so the scrollbar appears, innerWidth will be the same
value (this is wrong)


Expected Results:  It would make more sense for innerWidth to return the
available space (window size minus scrollbar width)

Does IE have innerWidth?  If not, this is invalid, since innerWidth in NS4 does
not account for the scrollbar and we only have the property for NS4 compat.

You may want to just use document.body.offsetWidth.....

Just checked and IE does not support window.innerWidth...  so our behavior is
correct as far as NS4 compat goes.
