variable passing

Modifying parent data from modal dialog by dace
Posted: 29 Mar 05

It's possible to modify the variables of a parent window from a modal dialog.  The key is to pass in "window.self" as the second parameter to showModalDialog:

In the parent:

CODE

parentVar = "set by parent";
vRv = window.showModalDialog("modalWindow.html",window.self, "");

In the modal:

CODE

dialogArguments.parentVar = "set by modal";

This allows you to change multiple variables in the parent, in case just the return value of the modal isn't enough.
