Properties

Readonly AT_TARGET

AT_TARGET: number

Readonly BUBBLING_PHASE

BUBBLING_PHASE: number

Readonly CAPTURING_PHASE

CAPTURING_PHASE: number

Event

Event: object

Type declaration

  • constructor: function
    • new __type(type: string, eventInitDict?: EventInit): Event
    • Parameters

      • type: string
      • Optional eventInitDict: EventInit

      Returns Event

  • Readonly AT_TARGET: number
  • Readonly BUBBLING_PHASE: number
  • Readonly CAPTURING_PHASE: number
  • Readonly NONE: number
  • prototype: Event

Readonly NONE

NONE: number

altKey

altKey: boolean

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.

cancelBubble

cancelBubble: boolean

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.

changedTouches

changedTouches: Touch[]

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.

ctrlKey

ctrlKey: boolean

Readonly currentTarget

currentTarget: EventTarget | null

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

Readonly defaultPrevented

defaultPrevented: boolean

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

Readonly eventPhase

eventPhase: number

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

Readonly isTrusted

isTrusted: boolean

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

metaKey

metaKey: boolean

returnValue

returnValue: boolean

shiftKey

shiftKey: boolean

Readonly srcElement

srcElement: EventTarget | null
deprecated

target

target: Element

targetTouches

targetTouches: Touch[]

Readonly timeStamp

timeStamp: number

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

touches

touches: Touch[]

type

type: string

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.

    Returns EventTarget[]

initEvent

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

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

    Returns void

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.

    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.

    Returns void

stopPropagation

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

    Returns void
