The Window.parent property is a reference to the parent of the current window or subframe.

If a window does not have a parent, its parent property is a reference to itself.

When a window is loaded in an <iframe>, <object>, or <frame>, its parent is the window with the element embedding the window.


var parentWindow = window.parent;


if (window.parent != {
  // We're deeper than one down
