§Properties

readonly AT_TARGET: number

[src]

readonly bubbles: boolean

[src]

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 BUBBLING_PHASE: number

[src]

readonly cancelable: boolean

[src]

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.

cancelBubble: boolean

[src]

readonly CAPTURING_PHASE: number

[src]

readonly composed: boolean

[src]

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 currentTarget: EventTarget | null

[src]

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

readonly defaultPrevented: boolean

[src]

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

readonly eventPhase: number

[src]

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

readonly isTrusted: boolean

[src]

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

readonly NONE: number

[src]

returnValue: boolean

[src]

readonly srcElement: EventTarget | null

[src]

readonly target: EventTarget | null

[src]

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

readonly timeStamp: DOMHighResTimeStamp

[src]

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

readonly type: string

[src]

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

§Methods

composedPath(): EventTarget[]

[src]

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(

type: string,

bubbles?: boolean,

cancelable?: boolean,

): void

[src]

preventDefault(): void

[src]

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(): void

[src]

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(): void

[src]

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