DOM Question wrote: 

Is there an equivalent to the following IE Javascript code? 

newStyleSheet=document.createStyleSheet(); 
newStyleSheet.addRule(a,b); 

In other words, how can I create a dynamic stylesheet that can be 
accessed something like: 

document.stylesheet[0].rule[0] 
or 
document.stylesheet[0].cssrule[0] 
or 
whatever? 

-----
This is unfortunately impossible in mozilla, the standard way of 
creating stylesheets would be: 

var newStyleSheet = document.implementation.createCSSStyleSheet("a 
title", "a media"); 

but that's unfortunately not implemented in mozilla either, and even if 
this would work there's no standard way to associate a new stylesheet 
with a document. Feel free to file bugs on these missing features (DOM 
Level 2) in http://bugzilla.mozilla.org.

Thanks in advance!

This is something we'd wanto implement in mozilla as we have time to but
currently there are more important things to fix so I'll haveto mark this as
Future for now, thanks for filing this tho! :-)

Nominating this bug for nsbeta1 on behalf of [e-mail].

Removing nsbeta1 nomination -- there was a misunderstanding and some "approved
out features" were nominated by mistake! Sorry!

OK. So document.implementation.createCSSStyleSheet() is completely useless. 
From
http://www.w3.org/TR/2000/REC-DOM-Level-2-Style-20001113/css.html#CSS-DOMImplementationCSS:

    This interface allows the DOM user to create a CSSStyleSheet outside the
    context of a document. There is no way to associate the new CSSStyleSheet with
    a document in DOM Level 2.

In other words, there is nothing useful you can do with the stylesheet it gives
you.  Daniel, this seems like something that the CSS WG should take a look
at....  Either remove this or make it useful.  ;)

Creating a <style> element and appending it into the DOM will create a useful
(attached to document) stylesheet in the meantime.
Futuring, but please let me know if I'm missing something that makes this worth
implementing in the near term.

No plans to work on this any time in the foreseeable future, so to default owner.

This would be indeed a usefull feature.

Why does following assignment don't work?

var styleSheet = document.implementation.createCSSStyleSheet("Test", "all");
document.styleSheets[document.styleSheets.length - 1] = styleSheet;

Theoretically this should work or not?

No, document.styleSheets[document.styleSheets.length - 1] can't be set.
