The HTMLFrameSetElement interface provides special properties (beyond those of the regular HTMLElement interface they also inherit) for manipulating <frameset> elements.
Instance properties
Inherits properties from its parent, HTMLElement.
HTMLFrameSetElement.cols-
A string structured as a comma-separated list specifying the width of each column inside a frameset.
HTMLFrameSetElement.rows-
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, HTMLElement.
Event handlers
The HTMLElement events are inherited.
The following 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.
