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.
ReadonlyNONEReadonlypersistedFor the pageshow event, returns false if the page is newly being loaded (and the load event will fire). Otherwise, returns true.
For the pagehide event, returns false if the page is going away for the last time. Otherwise, returns true, meaning that (if nothing conspires to make the page unsalvageable) the page might be reused if the user navigates back to this page.
Things that can cause the page to be unsalvageable include:
The user agent decided to not keep the Document alive in a session history entry after unload Having iframes that are not salvageable Active WebSocket objects Aborting a Document
ReadonlysrcReadonlytargetReturns 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.
ReadonlytypeReturns 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.
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.
The PageTransitionEvent is fired when a document is being loaded or unloaded.
