Description

Though the Frame object is sometimes referred to, there is, strictly
speaking, no such object. All frames within a browser window are
instances of the Window object, and they contain the same properties
and support the same methods and event handlers as the Window object.
See the Window object and its properties, methods, and event handlers
for details.

There are a few practical differences between Window objects that
represent top-level browser windows and those that represent frames
within a browser window, however:

• When the defaultStatus property is set for a
  frame, the specified status message is visible only when the mouse is
  within that frame.
  




• The top and parent properties
  of a top-level browser window always refer to the top-level window
  itself. These properties are really useful only for frames.
  




• The close( ) method is not useful for Window
  objects that are frames.
