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_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.
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.
ReadonlyNONEReadonlyreasonReturns the WebSocket connection close reason provided by the server.
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.
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.
Optionalbubbles: booleanOptionalcancelable: booleanIf 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.
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.
