Window: frameElement property - Web APIs | MDN
Window: frameElement property Baseline Widely available
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>
.
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.
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/";
}
window.frames
returns an array-like object, listing the direct
sub-frames of the current window.
window.parent
returns the parent window, which is the window
containing the frameElement
of the child window.
