interface Event

An event which takes place in the DOM.

variable

var Event: { … }

An event which takes place in the DOM.

Constructors

`constructor`

new Event(type: string, eventInitDict?: EventInit): Event

Properties

`bubbles`

readonly bubbles: boolean

Returns true or false depending on how event was initialized. True if event goes through its target's ancestors in reverse tree order, and false otherwise.

`cancelBubble`

cancelBubble: boolean

Deprecated.

`cancelable`

readonly cancelable: boolean

Returns true or false depending on how event was initialized. Its return value does not always carry meaning, but true can indicate that part of the operation during which event was dispatched, can be canceled by invoking the preventDefault() method.

`composed`

readonly composed: boolean

Returns true or false depending on how event was initialized. True if event invokes listeners past a ShadowRoot node that is the root of its target, and false otherwise.

`currentTarget`

readonly currentTarget: EventTarget | null

Returns the object whose event listener's callback is currently being invoked.

`defaultPrevented`

readonly defaultPrevented: boolean

Returns true if preventDefault() was invoked successfully to indicate cancellation, and false otherwise.

`eventPhase`

readonly eventPhase: number

Returns the event's phase, which is one of NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE.

`isTrusted`

readonly isTrusted: boolean

Returns true if event was dispatched by the user agent, and false otherwise.

`returnValue`

returnValue: boolean

Deprecated.

`srcElement`

readonly srcElement: EventTarget | null

Deprecated.

`target`

readonly target: EventTarget | null

Returns the object to which event is dispatched (its target).

`timeStamp`

readonly timeStamp: number

Returns the event's timestamp as the number of milliseconds measured relative to the time origin.

`type`

readonly type: string

Returns the type of event, e.g. "click", "hashchange", or "submit".

`NONE`

readonly NONE: 0

readonly NONE: 0

`CAPTURING_PHASE`

readonly CAPTURING_PHASE: 1

readonly CAPTURING_PHASE: 1

`AT_TARGET`

readonly AT_TARGET: 2

readonly AT_TARGET: 2

`BUBBLING_PHASE`

readonly BUBBLING_PHASE: 3

readonly BUBBLING_PHASE: 3

`prototype`

readonly prototype: Event

Methods

`composedPath`

composedPath(): EventTarget[]

Returns the invocation target objects of event's path (objects on which listeners will be invoked), except for any nodes in shadow trees of which the shadow root's mode is "closed" that are not reachable from event's currentTarget.

`initEvent`

initEvent(type: string, bubbles?: boolean, cancelable?: boolean): void

Deprecated.

`preventDefault`

preventDefault(): void

If invoked when the cancelable attribute value is true, and while executing a listener for the event with passive set to false, signals to the operation that caused event to be dispatched that it needs to be canceled.

`stopImmediatePropagation`

stopImmediatePropagation(): void

Invoking this method prevents event from reaching any registered event listeners after the current one finishes running and, when dispatched in a tree, also prevents event from reaching any other objects.

`stopPropagation`

stopPropagation(): void

When dispatched in a tree, invoking this method prevents event from reaching any objects other than the current object.
