WindowEventHandlers

In This Article

WindowEventHandlers mixin describes the event handlers common to several interfaces like Window, or HTMLBodyElement and HTMLFrameSetElement. Each of these interfaces can implement additional specific event handlers.

Note: WindowEventHandlers is a mixin and not an interface; you can't actually create an object of type WindowEventHandlers.
