Event Object Properties

Although event handlers in the DHTML Object Model do not receive parameters directly, a handler can query the event object for the following event properties.

Available Properties

cancelBubble	Sets or retrieves whether the current event should bubble up the hierarchy of event handlers.
type	Sets or retrieves the event name from the event object.

Remarks

In Asynchronous JavaScript and XML (AJAX) applications, client requests that do not trigger traditional page navigation should update the hash property. This lets the Back button function more predictably. The URL fragment (bookmark) can be set by script. The value is appended to the displayed URL, and the navigation is saved in the browser history.

There is no public standard that applies to this event.
