How to access child window from parent window through javascript?

Question

Suppose we open a popup through javascript when a link is clicked on parent window.

As everybody knows that parent window elements can be accessed from child window using the window.opener() function.

Is it possible to do exactly reverse ? Can parent window access the information about the child window ?

Answer 1

You mean something like this:

a=window.open()
a.document.write("<div id='mydiv'>test</div>")
a.document.getElementById("mydiv")
