Parent window calling functions in a child page

[jovialjonny]

Hi,
I've just realised I may have wasted a week's coding...
Is it possible for a parent window that has opened a child window via: var viewer = window.open("some url");
to then reference js functions contained in the child page?

I have a mehod in the page I just opened that I need to call from the parent in order to pass a variable, how can I do this? would something like:
viewer.addToViewer(theUrl)
be correct? (addToViewer is a function in the javascript file attached to the child page).

be correct?Yes, as long as the URL is in the same domain. Otherwise, you will get "Access Denied" or some other similar error.

Yes, you should be able to call a function from the child window by using viewer.functionName();
