6.7. Communicating with a New Window

6.7.1. Problem

You want to access the subwindow and its document from scripts in the main window.

6.7.2. Solution

Provided you preserve the reference to the subwindow returned by the window.open() method, and if the content of the subwindow is served by the same domain and server as the main window document, you can access any property or method that you are able to from scripts within the subwindow.
