Readonly AT_TARGET

AT_TARGET: number





Readonly NONE

NONE: number

Readonly 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.

Readonly button

button: number

Readonly buttons

buttons: number


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.

Readonly clientX

clientX: number

Readonly clientY

clientY: 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.

Readonly 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 detail

detail: number

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.

Readonly metaKey

metaKey: boolean

Readonly movementX

movementX: number

Readonly movementY

movementY: number

Readonly offsetX

offsetX: number

Readonly offsetY

offsetY: number

Readonly pageX

pageX: number

Readonly pageY

pageY: number


params: XMouseParams

Readonly relatedTarget

relatedTarget: EventTarget | null


returnValue: boolean

Readonly screenX

screenX: number

Readonly screenY

screenY: number

Readonly shiftKey

shiftKey: boolean

Readonly srcElement

srcElement: EventTarget | null

Readonly target

target: EventTarget | null

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

Readonly timeStamp

timeStamp: number

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

Readonly type

type: string

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

Readonly view

view: Window | null

Readonly which

which: number

Readonly x

x: number

Readonly y

y: number

Static MouseEvent

MouseEvent: { constructor: any; prototype: MouseEvent }

Type declaration

  • constructor: function
    • new __type(type: string, eventInitDict?: MouseEventInit): MouseEvent
    • Parameters

      • type: string
      • Optional eventInitDict: MouseEventInit

      Returns MouseEvent

  • prototype: MouseEvent



  • 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[]


  • getModifierState(keyArg: string): boolean
  • Parameters

    • keyArg: string

    Returns boolean


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

    • type: string
    • Optional bubbles: boolean

    Returns void


  • initMouseEvent(typeArg: string, canBubbleArg: boolean, cancelableArg: boolean, viewArg: Window, detailArg: number, screenXArg: number, screenYArg: number, clientXArg: number, clientYArg: number, ctrlKeyArg: boolean, altKeyArg: boolean, shiftKeyArg: boolean, metaKeyArg: boolean, buttonArg: number, relatedTargetArg: EventTarget | null): void
  • Parameters

    • typeArg: string
    • canBubbleArg: boolean
    • cancelableArg: boolean
    • viewArg: Window
    • detailArg: number
    • screenXArg: number

    • relatedTargetArg: EventTarget | null

    Returns void


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

    Returns void
