Window.frameElement

The Window.frameElement property returns the element (such as <iframe> or <object>) in which the window is embedded.

Note: Despite this property's name, it works for documents embedded within any embedding point, including <object>, <iframe>, or <embed>.

Syntax

const frameEl = window.frameElement

Value

The element which the window is embedded into. If the window isn't embedded into another document, or if the document into which it's embedded has a different origin, the value is null instead.

Example

const frameEl = window.frameElement;
// If we're embedded, change the containing element's URL to 'https://mozilla.org/'
if (frameEl) {
  frameEl.src = 'https://mozilla.org/';
}
