 This method allows the dispatch of events into the implementation's
event model. The event target of the event is the
EventTarget object on which dispatchEvent
is called.

Params:
  • evt –  The event to be dispatched.
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]
  .
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.

 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.

Params:
  • 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.

 This method allows the removal of an event listener, independently of
the associated event group. Calling removeEventListenerNS
 with arguments which do not identify any currently registered
EventListener on the EventTarget has no
effect.

Params:

  associated with the event for which the user registered the event
  listener.
  • type –  Refer to the
  EventTarget.removeEventListener() method for a

  • listener –  Refer to the
  EventTarget.removeEventListener() method for a
  description of this parameter.
