This method is deprecated in favor of standard stopPropagation and is removed in Gecko 1.9. | Event | |
| DOM 2 Events preventDefault():void
Cancels the event if it is cancelable, without stopping further propagation of the event. | Event | |
| DOM 3 Events stopImmediatePropogation():void
Prevents other event listeners from being triggered and, unlike
Event.stopPropagation() its effect is immediate . | Event | |
| DOM 2 Events stopPropogation():void

deferred until all event listeners attached on the Event.currentTarget
have been triggered . | Event | |

Hide Inherited Public Properties
Show Inherited Public Propertiesdata:* [read-only] | Introduced in: | DOM 3 Events |
A string holding the message passed from the other window.

| HTML 5 lastEventId | property |
lastEventId:DOMString [read-only] | Introduced in: | DOM 3 Events |
Returns the last event ID, for server-sent events.

| HTML 5 origin | property |
origin:DOMString [read-only] | Introduced in: | DOM 3 Events |
Returns the origin of the message, for server-sent events and cross-document messaging.
The origin of the window that sent the message at the time postMessage was called. This string is the concatenation of the protocol and "://", the host name if one exists, and ":" followed by a port number if a port is present and differs from the default port for the given protocol. Examples of typical origins are http://example.org (implying port 443), http://example.net (implying port 80), and http://example.com:8080. Note that this origin is not guaranteed to be the current or future origin of that window, which might have been navigated to a different location since postMessage was called.

Parameters
typeArg:DOMString — Specifies Event.type, the local name of the event type.

| |
dataArg:DOMString — The message being sent.
| |
originArg:DOMString — The origin of the document that sent the message (typically the scheme, hostname, and port of the document, but not its path or fragment identifier).
| |
lastEventIdArg:WindowProxy — The last event ID string of the event source.
| |
sourceArg:MessagePortArray — The WindowProxy of the browsing context of the Window object from which the message came.
| |
portsArg:* — The MessagePortArray being sent, if any.
