MessageEvent class - typings.core library

Constructors

MessageEvent(String type, [MessageEventInit<T>? eventInitDict]): factory

Properties

atTarget → num: Available on Event, provided by the Event$Typings extension

no setter
bubbles → bool: Available on Event, provided by the Event$Typings extension
Returns true or false depending on how event was initialized. True if event goes through its target's ancestors in reverse tree order, and false otherwise.
no setter
bubblingPhase → num: Available on Event, provided by the Event$Typings extension

no setter
cancelable → bool: Available on Event, provided by the Event$Typings extension
Returns true or false depending on how event was initialized. Its return value does not always carry meaning, but true can indicate that part of the operation during which event was dispatched, can be canceled by invoking the preventDefault() method.
no setter
cancelBubble ↔ bool: Available on Event, provided by the Event$Typings extension
@deprecated
getter/setter pair
capturingPhase → num: Available on Event, provided by the Event$Typings extension

no setter
composed → bool: Available on Event, provided by the Event$Typings extension
Returns true or false depending on how event was initialized. True if event invokes listeners past a ShadowRoot node that is the root of its target, and false otherwise.
no setter
composedPath ↔ List<EventTarget> Function(): Available on Event, provided by the Event$Typings extension

getter/setter pair
currentTarget → EventTarget?: Available on Event, provided by the Event$Typings extension
Returns the object whose event listener's callback is currently being invoked.
no setter
data → T: Available on MessageEvent<T>, provided by the MessageEvent$Typings extension
Returns the data of the message.
no setter
defaultPrevented → bool: Available on Event, provided by the Event$Typings extension
Returns true if preventDefault() was invoked successfully to indicate cancelation, and false otherwise.
no setter
eventPhase → num: Available on Event, provided by the Event$Typings extension
Returns the event's phase, which is one of NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE.
no setter
hashCode → int: The hash code for this object.
no setterinherited
initEvent ↔ void Function(String, [bool?, bool?]): Available on Event, provided by the Event$Typings extension

getter/setter pair
initMessageEvent ↔ void Function(String, [bool?, bool?, dynamic, String?, String?, Object?, List<MessagePort>?]): Available on MessageEvent<T>, provided by the MessageEvent$Typings extension

getter/setter pair
isTrusted → bool: Available on Event, provided by the Event$Typings extension
Returns true if event was dispatched by the user agent, and false otherwise.
no setter
lastEventId → String: Available on MessageEvent<T>, provided by the MessageEvent$Typings extension
Returns the last event ID string, for server-sent events.
no setter
none → num: Available on Event, provided by the Event$Typings extension

no setter
origin → String: Available on MessageEvent<T>, provided by the MessageEvent$Typings extension
Returns the origin of the message, for server-sent events and cross-document messaging.
no setter
ports → ReadonlyArray<MessagePort>: Available on MessageEvent<T>, provided by the MessageEvent$Typings extension
Returns the MessagePort array sent with the message, for cross-document messaging and channel messaging.
no setter

getter/setter pair
returnValue ↔ bool: Available on Event, provided by the Event$Typings extension
@deprecated
getter/setter pair
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
source → Object?: Available on MessageEvent<T>, provided by the MessageEvent$Typings extension
Returns the WindowProxy of the source window, for cross-document messaging, and the MessagePort being attached, in the connect event fired at SharedWorkerGlobalScope objects.
no setter
srcElement → EventTarget?: Available on Event, provided by the Event$Typings extension

no setter
stopImmediatePropagation ↔ void Function(): Available on Event, provided by the Event$Typings extension

getter/setter pair
stopPropagation ↔ void Function(): Available on Event, provided by the Event$Typings extension

getter/setter pair
target → EventTarget?: Available on Event, provided by the Event$Typings extension
Returns the object to which event is dispatched (its target).
no setter
timeStamp → num: Available on Event, provided by the Event$Typings extension
Returns the event's timestamp as the number of milliseconds measured relative to the time origin.
no setter
type → String: Available on Event, provided by the Event$Typings extension
Returns the type of event, e.g. "click", "hashchange", or "submit".
