Window: parent property

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.

Value

A Window or iframe object.

Examples

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