25.90. Element.addEventListener( ): register an event handlerDOM Level 2 Events:25.90.1. Synopsisvoid addEventListener(String type, Function listener, boolean useCapture); 25.90.1.1. Arguments
25.90.2. DescriptionThis method adds the specified event-listener function to the set of listeners registered on this node to handle events of the specified type. If useCapture is true, the listener is registered as a capturing event listener. If useCapture is false, it is registered as a normal event listener. addEventListener( ) may be called multiple times to register multiple event handlers for the same type of event on the same node. Note, however, that the DOM makes no guarantees about the order in which multiple event handlers are invoked. If the same event-listener function is registered twice on the same node with the same type and useCapture arguments, the second registration is simply ignored. If a new event listener is registered on this node while an event is being handled at this node, the new event listener is not invoked for that event. When a node is duplicated with Node.cloneNode( ) or Document.importNode( ), the event listeners registered for the original node are not copied. This method is also defined by, and works analogously on, the Document and Window objects. 25.90.3. See AlsoEvent; Chapter 17 |
