Syntax

HRESULT value = object.put_cancelBubble( v);HRESULT value = object.get_cancelBubble(* p);

Type: VARIANT_BOOL

VARIANT_TRUE (true)

Stop the event from propagating to the parent.

VARIANT_FALSE (false)

Standards information

There are no standards that apply here.

Remarks

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.

Note  The IDOMEvent::cancelBubble property is provided for backward compatibility. Use the IDOMEvent::stopPropagation or IDOMEvent::stopImmediatePropagation methods instead.
