AbstractOptionalinit: EventInitStatic ReadonlyAT_Static ReadonlyBUBBLING_Static ReadonlyCAPTURING_Static ReadonlyNONEReturns 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.
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.
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.
Returns the object whose event listener's callback is currently being invoked.
Returns true if preventDefault() was invoked successfully to indicate cancelation, and false otherwise.
Returns the event's phase, which is one of NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE.
Returns true if event was dispatched by the user agent, and false otherwise.
Returns the event's timestamp as the number of milliseconds measured relative to the time origin.
Returns the type of event, e.g. "click", "hashchange", or "submit".
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.
Extends the lifetime of the install and activate events dispatched on the global scope as part of the service worker lifecycle. This ensures that any functional events (like FetchEvent) are not dispatched until it upgrades database schemas and deletes the outdated cache entries.
