    Window.parent

    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.

    Syntax

    parentWindow = window.parent; 
    

    Example

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