How to access parent.document elements using JQuery in firefox?

Question

For example:

$(elementid,top.document).attr(attributeName) 

or

$(elementid,parent.document).attr(attributeName) 

works in IE or Chrome but doesn't work in Firefox.

Does anyone know what the firefox equivalence is?

Thanks!

Answer 1

What about:

window.parent.$(elementid).attr(attributeName); 

Answer 2

Try this:

$("#myid", top.document);  

or

$("#myid", parent.document.body);
