Class DOMEventFacade
Wraps a DOM event, properties requiring browser abstraction are
fixed here. Provids a security layer when required.
Properties

Methods
void
halt
(
immediate
)
Stops the event propagation and prevents the default
event behavior.
- Parameters:
-
immediate
<boolean>
if true additional listeners
on the current target will not be executed
void
preventDefault
(
returnValue
)
Prevents the event's default behavior
- Parameters:
-
returnValue
<string>
sets the returnValue of the event to this value
(rather than the default false value). This can be used to add a customized
confirmation query to the beforeunload event).
private
void
resolve
(
)
Returns a wrapped node. Intended to be used on event targets,
so it will return the node's parent if the target is a text
node.
If accessing a property of the node throws an error, this is
probably the anonymous div wrapper Gecko adds inside text
nodes. This likely will only occur when attempting to access
the relatedTarget. In this case, we now return null because
the anonymous div is completely useless and we do not know
what the related target was because we can't even get to
the element's parent node.
void
stopImmediatePropagation
(
)
Stops the propagation to the next bubble target and
prevents any additional listeners from being exectued
on the current target.
void
stopPropagation
(
)
Stops the propagation to the next bubble target
