Gets or sets a value that indicates whether an event should be stopped from propagating up from the current target.
HRESULT value = object.put_cancelBubble( v);HRESULT value = object.get_cancelBubble(* p);
Stop the event from propagating to the parent.
Allow the event to propagate upwards.
There are no standards that apply here.
If an event does not bubble by default, the IDOMEvent::cancelBubble property has no effect. For example, the HTMLFrameSiteEvents::onclick event bubbles and you can cancel it, but the HTMLFrameSiteEvents::onfocus event does not.
Also, you can use IDOMEvent::cancelBubble only to stop events in the bubbling phase. It does not stop events from being captured. For more information, see IDOMEvent::eventPhase.
