Readonly AT_Readonly BUBBLING_Readonly CAPTURING_Readonly NONEReadonly altReadonly bubblesReturns 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 buttonReadonly buttonsReadonly cancelableReturns 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 clientXReadonly clientYReadonly composedReturns 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 ctrlReadonly currentReturns the object whose event listener's callback is currently being invoked.
Readonly defaultReturns true if preventDefault() was invoked successfully to indicate cancelation, and false otherwise.
Readonly detailReadonly eventReturns the event's phase, which is one of NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE.
Readonly heightReadonly isReadonly isReturns true if event was dispatched by the user agent, and false otherwise.

Readonly tiltXReadonly tiltYReadonly timeReturns the event's timestamp as the number of milliseconds measured relative to the time origin.
Readonly twistReadonly typeReturns the type of event, e.g. "click", "hashchange", or "submit".
Readonly viewReadonly whichReadonly widthReadonly xReadonly yReturns 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.
Available only in secure contexts.
