Interface EventListener
public interface EventListener
The EventListener
interface is the primary method for handling events. Users implement the EventListener
interface and register their listener on an EventTarget
using the AddEventListener
method. The users should also remove their EventListener
from its EventTarget
after they have completed using the listener.
When a Node
is copied using the cloneNode
method the EventListener
s attached to the source Node
are not attached to the copied Node
. If the user wishes the same EventListener
s to be added to the newly created copy the user must add them manually.
