[Javascript] Null Parent

Fri Jul 9 08:37:42 CDT 2004

  From the just created window I think that "opener" would be the right 
name for it's /parent/.

opener.parent.browserFrame.document
  |      |          |
  |      |          =----> the Frame
  |      =---------> the Frameset
  =--------> the window.open Caller
