All Implemented Interfaces:

public class EventListener
extends DomShared

Introduced in DOM Level 2 The EventListener interface is the primary method for handling events. Users implement the EventListener interface and register their listener on an EventTarget using the AddEventListener method. The users should also remove their EventListener from its EventTarget after they have completed using the listener. When a Node is copied using the cloneNode method the EventListeners attached to the source Node are not attached to the copied Node. If the user wishes the same EventListeners to be added to the newly created copy the user must add them manually.
