addEventListener( )
Adds an event listener to the set of event listeners for this node.
dispatchEvent( )
Dispatches a synthetic event to this node.
removeEventListener( )
Removes an event listener from the set of listeners of this Document node.
In DOM implementations that support events (i.e., those that support the "Events" feature), all nodes in the document tree implement this interface and maintain a set or list of event listener functions for each node. The addEventListener( ) and removeEventListener( ) methods allow listener functions to be added and removed from this set.
