Properties

Readonly AT_TARGET

AT_TARGET: 2

Readonly BUBBLING_PHASE

BUBBLING_PHASE: 3

Readonly CAPTURING_PHASE

CAPTURING_PHASE: 1

Readonly NONE

NONE: 0

Readonly bubbles

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.

MDN Reference

cancelBubble

cancelBubble: boolean

Deprecated

MDN Reference

Readonly cancelable

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.

MDN Reference

canvasX

canvasX: number

canvasY

canvasY: number

Optional click_time

click_time?: number

Readonly composed

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.

MDN Reference

Readonly currentTarget

currentTarget: EventTarget

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

MDN Reference

Readonly defaultPrevented

defaultPrevented: boolean

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

MDN Reference

Optional delta

delta?: number

Optional deltaX

deltaX?: number

Optional deltaY

deltaY?: number

Readonly detail

detail: any

Returns any custom data event was created with. Typically used for synthetic events.

MDN Reference

dragging

dragging: boolean

Readonly eventPhase

eventPhase: number

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

MDN Reference

Optional eventType

eventType?: string

Readonly isTrusted

isTrusted: boolean

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

MDN Reference

Optional layerY

layerY?: number

returnValue

returnValue: boolean

Deprecated

MDN Reference

Readonly srcElement

srcElement: EventTarget

Deprecated

MDN Reference

Readonly target

target: EventTarget

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

MDN Reference

Readonly timeStamp

timeStamp: number

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

MDN Reference

Readonly type

type: string

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

MDN Reference

Optional wheel

wheel?: number

Optional wheelDelta

wheelDelta?: number

Optional wheelDeltaY

wheelDeltaY?: number

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.

    MDN Reference

    Returns EventTarget[]

initCustomEvent

  • initCustomEvent(type, bubbles?, cancelable?, detail?): void

  • Parameters

    • type: string
    • Optional bubbles: boolean
    • Optional cancelable: boolean
    • Optional detail: any

    Returns void

    Deprecated

    MDN Reference

initEvent

  • initEvent(type, bubbles?, cancelable?): void

  • Parameters

    • type: string
    • Optional bubbles: boolean
    • Optional cancelable: boolean

    Returns void

    Deprecated

    MDN Reference

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.

    MDN Reference

    Returns void

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.

    MDN Reference

    Returns void

stopPropagation

  • stopPropagation(): void

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

    MDN Reference

    Returns void
