MessageEvent
Types
event
type event = EventTypes.eventRecord fields
type_
Returns the type of event, e.g. "click", "hashchange", or "submit". Read more on MDN
target
Returns the object to which event is dispatched (its target). Read more on MDN
currentTarget
Returns the object whose event listener's callback is currently being invoked. Read more on MDN
eventPhase
Returns the event's phase, which is one of NONE, CAPTURING_PHASE, AT_TARGET, and BUBBLING_PHASE. Read more on MDN
bubbles
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. Read more on MDN
cancelable
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. Read more on MDN
defaultPrevented
Returns true if preventDefault() was invoked successfully to indicate cancelation, and false otherwise. Read more on MDN
composed
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. Read more on MDN
isTrusted
Returns true if event was dispatched by the user agent, and false otherwise. Read more on MDN
timeStamp
Returns the event's timestamp as the number of milliseconds measured relative to the time origin. Read more on MDN

origin
Returns the origin of the message, for server-sent events and cross-document messaging. Read more on MDN
source
Returns the WindowProxy of the source window, for cross-document messaging, and the MessagePort being attached, in the connect event fired at SharedWorkerGlobalScope objects. Read more on MDN

Returns the MessagePort array sent with the message, for cross-document messaging and channel messaging. Read more on MDN

Values
composedPath
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. Read more on MDN
let composedPath: t<'t> => array<eventTarget>make
let make: ( ~type_: string, ~eventInitDict: messageEventInit<'t>=?,) => t<'t>preventDefault
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. Read more on MDN
let preventDefault: t<'t> => unitstopImmediatePropagation
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. Read more on MDN
let stopImmediatePropagation: t<'t> => unitstopPropagation
When dispatched in a tree, invoking this method prevents event from reaching any objects other than the current object. Read more on MDN
