public interface NodeEventTarget extends EventTarget
Method Summary | |
---|---|
void | addEventListenerNS(String namespaceURI, String type, EventListener listener, boolean useCapture, Object evtGroup)
This method allows the registration of an event listener in a
specified group or the default group and, depending on the
useCapture parameter, on the capture phase of the DOM
event flow or its target and bubbling phases. |
boolean | dispatchEvent(Event evt)
This method allows the dispatch of events into the implementation's
event model. |
EventSupport | getEventSupport()
Returns the event support instance for this node, or null if any. |
NodeEventTarget | getParentNodeEventTarget()
Returns the parent node event target. |
void | removeEventListenerNS(String namespaceURI, String type, EventListener listener, boolean useCapture)
This method allows the removal of an event listener, independently of
the associated event group. |
useCapture
parameter, on the capture phase of the DOM
event flow or its target and bubbling phases.Parameters: namespaceURI Specifies the Event.namespaceURI
associated with the event for which the user is registering. type Refer to the EventTarget.addEventListener()
method for a description of this parameter. listener Refer to the
EventTarget.addEventListener()
method for a
description of this parameter. useCapture Refer to the
EventTarget.addEventListener()
method for a
description of this parameter. evtGroup The object that represents the event group to
associate with the EventListener
(see also ). Use
null
to attach the event listener to the default
group.

EventTarget
object on which dispatchEvent
is called.Parameters: evt The event to be dispatched.
Returns: Indicates whether any of the listeners which handled the
event called Event.preventDefault()
. If
Event.preventDefault()
was called the returned value
is false
, else it is true
.
Throws: EventException
UNSPECIFIED_EVENT_TYPE_ERR: Raised if the Event.type
was not specified by initializing the event before
dispatchEvent
was called. Specification of the
Event.type
as null
or an empty string
will also trigger this exception.
DISPATCH_REQUEST_ERR: Raised if the Event
object is
already being dispatched. DOMException
NOT_SUPPORTED_ERR: Raised if the Event
object has not
been created using DocumentEvent.createEvent()
.
INVALID_CHARACTER_ERR: Raised if Event.type
is not
an NCName as defined in [XML Namespaces 1.1]
.
removeEventListenerNS
with arguments which do not identify any currently registered
EventListener
on the EventTarget
has no
effect.Parameters: namespaceURI Specifies the Event.namespaceURI
associated with the event for which the user registered the event
listener. type Refer to the
EventTarget.removeEventListener()
method for a
description of this parameter. listener Refer to the
EventTarget.removeEventListener()
method for a
description of this parameter. useCapture Refer to the
EventTarget.removeEventListener()
method for a
description of this parameter.
