Focus transfer between browser windows

[Amaya Gomez]

I would be grateful if someone could give me a tip to my problem:

• I have two HTML-Pages containing both a Java Script (JDK 1.1).
• The user opens a Browser window containing the first page.
• When the Java Script at this page is executed, it opens a new browser window containing the second page, using the window.open("HTLM-Page name") method.
• That means a Java Script contained in the second window can handle the first one using the window.opener object reference.
• I want to give the user the oportunity to go back from the second window to the first one. All I have to do is to call the method window.opener.focus(). The problem is, if the user already closed this first window, I can‚t transfer the focus anymore. I have to create then a new window containing the page at this first window.
• My question ist how can I ask whether the first window was closed or if it's still opened?
• I already tried to ask for the property window.opener.closed, but it always gives the value "false" back no matter if the first window is closed or not.

Tank you very much.
