111133 - getPropertyValue("left") throws NS_ERROR_NOT_IMPLEMENTED for getComputedStyle()

Status: RESOLVED DUPLICATE of bug 109523

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

Description

[Marcus Fellinger]

Loading the attached HTML-file, I get the following error in the Javascript Console:

Error: uncaught exception: [Exception... "Component returned failure code:
0x80004001 (NS_ERROR_NOT_IMPLEMENTED)
[nsIDOMCSSStyleDeclaration.getPropertyValue]"  nsresult: "0x80004001
(NS_ERROR_NOT_IMPLEMENTED)"  location: "JS frame ::
file:///home/marcus/homepage/tests/getPropertyValue.html :: testPropertyValue ::
line 15"  data: no]

This is with a CVS-build from Nov 20, 2001.

The page should display the left-Property of the link "Book Reviews". Instead,
the value is not displayed, and the specified exception occurs.

You're asking for a nonsensical property ("left" is not defined on statically
positioned elements).  The CSS DOM spec does not say what should happen here and
the standards people are still bickering about it. So yes, this property is not
implemented for statically positioned elements and likely will not be until
there is some consensus on what it should do.

It works fine for positioned elements (for which it actually makes sense).
