An event which takes place in the DOM.

Constructors

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

Properties

readonly
AT_TARGET: number
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.

readonly
BUBBLING_PHASE: number
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.

cancelBubble: boolean
readonly
CAPTURING_PHASE: number
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.

readonly
currentTarget: EventTarget | null

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

readonly
defaultPrevented: boolean

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

readonly
eventPhase: number

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

readonly
isTrusted: boolean

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

readonly
NONE: number
readonly
target: EventTarget | null

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

readonly
timeStamp: number

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

readonly
type: string

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

Methods

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.

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.

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.

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