The Event
interface represents any event of the DOM. It contains common properties and methods to any event.
A lot of other interfaces implement the Event
interface, either directly or by implementing another interface which does so:
AnimationEvent
AudioProcessingEvent
BeforeInputEvent
BeforeUnloadEvent
BlobEvent
ClipboardEvent
CloseEvent
CompositionEvent
CSSFontFaceLoadEvent
CustomEvent
DeviceLightEvent
DeviceMotionEvent
DeviceOrientationEvent
DeviceProximityEvent
DOMTransactionEvent
DragEvent
EditingBeforeInputEvent
ErrorEvent
FetchEvent
FocusEvent
GamepadEvent
HashChangeEvent
IDBVersionChangeEvent
InputEvent
KeyboardEvent
MediaStreamEvent
MessageEvent
MouseEvent
MutationEvent
OfflineAudioCompletionEvent
PageTransitionEvent
PointerEvent
PopStateEvent
ProgressEvent
RelatedEvent
RTCDataChannelEvent
RTCIdentityErrorEvent
RTCIdentityEvent
RTCPeerConnectionIceEvent
SensorEvent
StorageEvent
SVGEvent
SVGZoomEvent
TimeEvent
TouchEvent
TrackEvent
TransitionEvent
UIEvent
UserProximityEvent
WebGLContextEvent
WheelEvent
Constructor
Event()
- Creates an
Event
object.
Properties
Event.bubbles
Read only- A boolean indicating whether the event bubbles up through the DOM or not.
Event.cancelBubble
- A nonstandard alternative to
Event.stopPropagation()
. Event.cancelable
Read only- A boolean indicating whether the event is cancelable.
Event.currentTarget
Read only- A reference to the currently registered target for the event.
Event.deepPath
- Returns an
Array
of nodes through which the event bubbled. Event.defaultPrevented
Read only- Indicates whether or not
event.preventDefault()
has been called on the event. Event.eventPhase
Read only- Indicates which phase of the event flow is being processed.
Event.explicitOriginalTarget
Read only- The explicit original target of the event (Mozilla-specific).
Event.originalTarget
Read only- The original target of the event, before any retargetings (Mozilla-specific).
Event.returnValue
- A nonstandard alternative to
Event.preventDefault()
andEvent.defaultPrevented
. (old Internet Explorer-specific). Event.scoped
Read only- A
Boolean
indicating whether the given event bubbles. If this value istrue
,deepPath
will only contain a target node. Event.srcElement
- A nonstandard alias for
Event.target
. (old Internet Explorer-specific) Event.target
Read only- A reference to the target to which the event was originally dispatched.
Event.timeStamp
Read only- The time that the event was created.
Event.type
Read only- The name of the event (case-insensitive).
Event.isTrusted
Read only- Indicates whether or not the event was initiated by the browser (after a user click for instance) or by a script (using an event creation method, like event.initEvent)
Methods
Event.initEvent()
- Initializes the value of an Event created. If the event has already being dispatched, this method does nothing.
Event.preventBubble()
Obsolete since Gecko 24- Prevents the event from bubbling. Obsolete, use
event.stopPropagation
instead. Event.preventCapture()
Obsolete since Gecko 24- Obsolete, use
event.stopPropagation
instead. Event.preventDefault()
- Cancels the event (if it is cancelable).
Event.stopImmediatePropagation()
- For this particular event, no other listener will be called. Neither those attached on the same element, nor those attached on elements which will be traversed later (in capture phase, for instance)
Event.stopPropagation()
- Stops the propagation of events further along in the DOM.
Event.getPreventDefault()
- Non-standard. Returns the value of
Event.defaultPrevented
. UseEvent.defaultPrevented
instead.
