call a parent javascript function from the child window

[Filiz Duman]

Is it possible to call a javascript function based in the parent window from
the child window ?
I do open a pop up window from the parent window with:

newwindow = window.open (...)

and assign a value from the child window to the parent window text field:

opener.document.forms["xxx"].elements["yyy"].value = valuename;

At this stage I would like to call another javascript function coded in the
parent window <script> part. I do not want to put the code in the child
window since it is more a validation check on the parent window, so every
time the value is passed to the parent window text field the validation
should fire. I played around with the events but all textfield events
(onFocus, on Blur) did not help me, since the textfield is disabled.
Any ideas ?
