789944 - DOM prototype objects don't have the right constructor

Status: RESOLVED FIXED

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

Description

[Erik Arvidsson]

All other browsers return true for expressions like these:

HTMLDivElement.prototype.constructor === HTMLDivElement

Firefox returns true if you use Date, RegExp etc

This works for WebIDL objects (e.g. XMLHttpRequest).  It'll work for HTMLDivElement once that's converted to WebIDL.

Comment 2

[Tom S [:evilpie]]

I think we could call this fixed now that all constructors are on WebIDL.

Comment 3

[Boris Zbarsky [:bzbarsky]]

CSSRule.prototype.constructor == CSSRule still tests false.  It has a constructor; it just throws when called.

Comment 4

[Boris Zbarsky [:bzbarsky]]

This is fixed for all spec-defined interfaces.
