The oncancel
property of the
GlobalEventHandlers
mixin is an EventHandler
for
processing cancel
events sent to a <dialog>
element.
The cancel
event fires when the user indicates a wish to dismiss a
<dialog>
. This event handler prevents the event from bubbling, so any
parent handlers are not notified of the event.
Syntax
target.oncancel = functionRef;
Value
functionRef
is a function name or a function
expression. The function receives an Event
object as its sole
argument.
Only one oncancel
handler can be assigned to an object at a time. You may
prefer to use the EventTarget.addEventListener()
method instead, since
it's more flexible.
