public interface DOMEventTarget

This interface is implemented by all DOMNode that supports DOM event model.

Method Summary

Methods

Modifier and Type	Method and Description
void	addEventListener(java.lang.String eventType, DOMEventListener listener) This method allows the registration of event listeners on the event target.
void	removeEventListener(java.lang.String eventType, DOMEventListener listener) This method allows the removal of event listeners from the event target.

Method Detail

addEventListener

void addEventListener(java.lang.String eventType,
                    DOMEventListener listener)

This method allows the registration of event listeners on the event target. If an DOMEventListener is added to an DOMEventTarget while it is processing an event, it will not be triggered by the current actions but may be triggered during a later stage of event flow, such as the bubbling phase.
If multiple identical DOMEventListeners are registered on the same DOMEventTarget with the same parameters the duplicate instances are discarded. They do not cause the DOMEventListener to be called twice and since they are discarded they do not need to be removed with the removeEventListener method.

Parameters:

eventType - the event type for which the user is registering. E.g. "click".

listener - the listener parameter takes an interface implemented by the user which contains the methods to be called when the event occurs.

removeEventListener

void removeEventListener(java.lang.String eventType,
                       DOMEventListener listener)

This method allows the removal of event listeners from the event target. If an DOMEventListener is removed from an DOMEventTarget while it is processing an event, it will not be triggered by the current actions. DOMEventListeners can never be invoked after being removed.
Calling removeEventListener with arguments which do not identify any currently registered DOMEventListener on the DOMEventTarget has no effect.

Parameters:

eventType - specifies the event type of the DOMEventListener being removed. E.g. "click".

listener - the DOMEventListener parameter indicates the DOMEventListener to be removed.
