{{APIRef("HTML DOM")}}{{deprecated_header}}

The HTMLFrameSetElement interface provides special properties (beyond those of the regular {{domxref("HTMLElement")}} interface they also inherit) for manipulating {{HTMLElement("frameset")}} elements.

Instance properties

Inherits properties from its parent, {{domxref("HTMLElement")}}.

• {{domxref("HTMLFrameSetElement.cols")}} {{deprecated_inline}}
  • : A string structured as a comma-separated list specifying the width of each column inside a frameset.
• {{domxref("HTMLFrameSetElement.rows")}} {{deprecated_inline}}
  • : A string structured as a comma-separated list specifying the height of each column inside a frameset.

Instance methods

No specific method; inherits methods from its parent, {{domxref("HTMLElement")}}.

Event handlers

The {{domxref("HTMLElement")}} events are inherited.

The following {{domxref("Window")}} onXYZ event handler properties are also available as aliases targeting the window object. However, it is advised to listen to them on the window object directly rather than on HTMLFrameSetElement.

[!NOTE] Using addEventListener() on HTMLFrameSetElement will not work for the onXYZ event handlers listed below. Listen to the events on the {{domxref("window")}} object instead.

• {{domxref("window.afterprint_event", "HTMLFrameSetElement.onafterprint")}}
  • : Fired after the associated document has started printing or the print preview has been closed.
• {{domxref("window.beforeprint_event", "HTMLFrameSetElement.onbeforeprint")}}
  • : Fired when the associated document is about to be printed or previewed for printing.
• {{domxref("window.beforeunload_event", "HTMLFrameSetElement.onbeforeunload")}}
  • : Fired when the window, the document and its resources are about to be unloaded.
• {{domxref("window.gamepadconnected_event", "HTMLFrameSetElement.ongamepadconnected")}}
  • : Fired when the browser detects that a gamepad has been connected or the first time a button/axis of the gamepad is used.
