101779 - getComputedStyle() does not work correctly in frames

Status: RESOLVED INVALID

(Core :: DOM: CSS Object Model, defect)

Description

[harishd]

Opening up this bug in response to the following message in the newsgroup:

I have placed an example at
http://www.dylanschiemann.com/examples/fontSize3.html
which seems to show that using getComputedStyle()
across frames does not work the way you are trying to
do so in the test harness.  This is a cross-document
issue... if you replace window with
document.getElementById("contentarea").contentDocument.documentElement.defaultView
, I get it to work as expected... See

I don't believe this is a bug per se, just an issue that developers must
remember to deal with when working with the DOM across documents.  For example,
you can't create an element in one document and use appendChild to add a
document in another frame's document.  In my opinion, this should be marked INVALID.

Yeah, this in invalid.  You want to use the view of the document the element is
actually in.  Note: inline style (using a style="" attribute) is shown correctly
cross-document because it does not rely on the stylesheets associated with a
particular document.

Marking invalid.
