DOM eVeNt MODeL aND ObjeCts

The DOM event model was introduced in DOM Level 2. It describes an event system where every
event has an event target. When an event reaches an event target, all registered event handlers on
the event target are triggered for that specific event. The following objects are described by the
DOM event model.

eventtarget
The EventTarget object is inherited by all HTMLElement objects in the DOM. This object provides
the means for the registration and removal of event handlers on the event target.
