Window.frameElement

Returns the element (such as <iframe> or <object>) in which the window is embedded, or null if the element is either top-level or is embedded into a document with a different script origin; that is, in cross-origin situations.

Syntax

JavaScript
<var>frameEl</var> = window.frameElement;
  • frameEl is 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 (such as having been located from a different domain), this is null.

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

Example

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