ReadonlyAT_ReadonlybubblesReturns 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.
ReadonlyBUBBLING_ReadonlycancelableReturns 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.
ReadonlyCAPTURING_ReadonlycomposedReturns 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.
ReadonlycurrentReturns the object whose event listener's callback is currently being invoked.
ReadonlydefaultReturns true if preventDefault() was invoked successfully to indicate cancelation, and false otherwise.
ReadonlyeventReturns the event's phase, which is one of NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE.
ReadonlyisReturns true if event was dispatched by the user agent, and false otherwise.
ReadonlyNONEOptional ReadonlypanelReadonlysrcReturns the object to which event is dispatched (its target).
ReadonlytimeReturns 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".
Static ReadonlyAT_Static ReadonlyBUBBLING_Static ReadonlyCAPTURING_Static ReadonlyNONEStatic ReadonlytypeReturns 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.
