Examples of org.w3c.dom.events.EventTarget.addEventListener()

org.w3c.dom.events.EventTarget.addEventListener()
This method allows the registration of event listeners on the event target. If an EventListener is added to an EventTarget which is currently processing an event the new listener will not be triggered by the current event.
If multiple identical EventListener s are registered on the same EventTarget with the same parameters the duplicate instances are discarded. They do not cause the EventListener to be called twice and since they are discarded they do not need to be removed with the removeEventListener method. @param type The event type for which the user is registering @param listener The listener parameter takes an interface implemented by the user which contains the methods to be called when the event occurs. @param useCapture If true, useCapture indicates that the user wishes to initiate capture. After initiating capture, all events of the specified type will be dispatched to the registered EventListener before being dispatched to any EventTargets beneath them in the tree. Events which are bubbling upward through the tree will not trigger an EventListener designated to use capture.
