Window parent property

parentA read-only property that returns the parent window of the current window.

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

When a window is loaded into an <iframe>, <object>, or <frame>, its parent window is the window that contains the element embedding the window.

Syntax:

window.parent

Example

parent.document.body.style.backgroundColor = "coral";

All browsers fully support the parent property:

Property
parent	Yes	Yes	Yes	Yes	Yes

Return Value:	The parent window object of the current window

Display the position of the parent window when a new window is opened:

Example

window.open("", "", "width=300, height=200");
document.getElementById("output").innerHTML = window.parent.location;
