Document: applets property

The applets property of the {{domxref("Document")}} returns an empty {{domxref("HTMLCollection")}}. This property is kept only for compatibility reasons; in older versions of browsers, it returned a list of the applets within a document.

[!NOTE] Support for the <applet> element has been removed by all browsers. Therefore, calling document.applets always returns an empty collection.

Value

An empty {{domxref("HTMLCollection")}}.
