ReadonlyAT_ReadonlyBUBBLING_ReadonlyCAPTURING_ReadonlyNONEReadonlybubblesReturns 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.
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.
ReadonlycodeReturns the WebSocket connection close code provided by the server.
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.
ReadonlyreasonReturns the WebSocket connection close reason provided by the server.
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".
ReadonlywasReturns true if the connection closed cleanly; false otherwise.
A CloseEvent is sent to clients using WebSockets when the connection is closed. This is delivered to the listener indicated by the WebSocket object's onclose attribute.
