The Event
interface represents any event which takes place in the DOM; some are user-generated (such as mouse or keyboard events), while others are generated by APIs (such as events that indicate an animation has finished running, a video has been paused, and so forth). There are many types of events, some of which use other interfaces based on the main Event
interface. Event
itself contains the properties and methods which are common to all events.

Constructor
Variables
cancelBubble:Bool
A historical alias to Event.stopPropagation()
. Setting its value to true
before returning from an event handler prevents propagation of the event.
read onlycomposed:Bool
A Boolean value indicating whether or not the event can bubble across the boundary between the shadow DOM and the regular DOM.
read onlycurrentTarget:EventTarget
A reference to the currently registered target for the event. This is the object to which the event is currently slated to be sent; it's possible this has been changed along the way through retargeting.
read onlydefaultPrevented:Bool
Indicates whether or not event.preventDefault()
has been called on the event.
read onlyexplicitOriginalTarget:EventTarget
The explicit original target of the event (Mozilla-specific).
read onlyisTrusted:Bool
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).
read onlyoriginalTarget:EventTarget
The original target of the event, before any retargetings (Mozilla-specific).
returnValue:Bool
A historical property introduced by Internet Explorer and eventually adopted into the DOM specification in order to ensure existing sites continue to work. Ideally, you should try to use Event.preventDefault()
and Event.defaultPrevented
instead, but you can use returnValue
if you choose to do so.
Methods
composedPath():Array<EventTarget>
Returns the event’s path (objects on which listeners will be invoked). This does not include nodes in shadow trees if the shadow root was created with its ShadowRoot.mode
closed.
initEvent(type:String, bubbles:Bool = false, cancelable:Bool = false):Void
Initializes the value of an Event created. If the event has already being dispatched, this method does nothing.
stopImmediatePropagation():Void
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)
