Type of data carried by this message.
If manually creating a message outside of a Hub, using Message.create is easier to use.
The constructor allows you to directly specify the Message.contains object, which may be useful if creating multiple Messages across different channels with the same payload.
Type of data carried by this message.
Name of the channel on which this message is originally to be dispatched.
Object containing the payload.
ReadonlyAT_ReadonlybubblesThe bubbles read-only property of the Event interface indicates whether the event bubbles up through the DOM tree or not.
ReadonlyBUBBLING_ReadonlycancelableThe cancelable read-only property of the Event interface indicates whether the event can be canceled, and therefore prevented as if the event never happened.
The cancelBubble property of the Event interface is deprecated.
ReadonlyCAPTURING_ReadonlychannelThe channel on which this Message was originally dispatched.
This can be relevant because in some situations (i.e. when calling Hub.getMessages() or Hub.sub) Messages can be returned from across several channels.
ReadonlycomposedThe read-only composed property of the or not the event will propagate across the shadow DOM boundary into the standard DOM.
ReadonlycontainsAn object containing the payload.
Generally you don't want to access this; you want to access payload. This is an object because we want to be able to use it as a unique identifier for Messages. Different messages would have the same scalar payload but be meaningfully distinct. Object equality in JS, however, means that ever object can be distinct, even if the actual payloads are the same.
ReadonlycurrentThe currentTarget read-only property of the Event interface identifies the element to which the event handler has been attached.
ReadonlydefaultThe defaultPrevented read-only property of the Event interface returns a boolean value indicating whether or not the call to Event.preventDefault() canceled the event.
ReadonlyeventThe eventPhase read-only property of the being evaluated.
ReadonlyisThe isTrusted read-only property of the when the event was generated by the user agent (including via user actions and programmatic methods such as HTMLElement.focus()), and false when the event was dispatched via The only exception is the click event, which initializes the isTrusted property to false in user agents.
ReadonlyNONEReadonlyorderA value used to order messages.
Strictly speaking, it is set on Message creation, not on Message dispatch, but when using the methods Hub.pub Messages are created at the time of dispatch.
The Event property returnValue indicates whether the default action for this event has been prevented or not.
ReadonlysrcThe deprecated Event.srcElement is an alias for the Event.target property.
ReadonlytargetThe read-only target property of the dispatched.
ReadonlytimeThe timeStamp read-only property of the Event interface returns the time (in milliseconds) at which the event was created.
ReadonlytypeThe type read-only property of the Event interface returns a string containing the event's type.
Static ReadonlyAT_Static ReadonlyBUBBLING_Static ReadonlyCAPTURING_StaticNAMEStatic ReadonlyNONEThe composedPath() method of the Event interface returns the event's path which is an array of the objects on which listeners will be invoked.
The preventDefault() method of the Event interface tells the user agent that if the event does not get explicitly handled, its default action should not be taken as it normally would be.
The stopImmediatePropagation() method of the If several listeners are attached to the same element for the same event type, they are called in the order in which they were added.
The stopPropagation() method of the Event interface prevents further propagation of the current event in the capturing and bubbling phases.
