Summary

Returns a reference to the topmost window in the window hierarchy.

Syntax

var topWindow = window.top;

Notes

Where the window.parent property returns the immediate parent of the current window, window.top returns the topmost window in the hierarchy of window objects.

This property is especially useful when you are dealing with a window that is in a subframe of a parent or parents, and you want to get to the top-level frameset.
