Window: frameElement property

{{ApiRef}}

The Window.frameElement property returns the element (such as {{HTMLElement("iframe")}} or {{HTMLElement("object")}}) in which the window is embedded.

[!NOTE] Despite this property's name, it works for documents embedded within any embedding point, including {{HTMLElement("object")}}, {{HTMLElement("iframe")}}, or {{HTMLElement("embed")}}.

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 {{glossary("origin")}}, the value is null instead.

Examples

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/";
}
