Interface IEventListener

Namespace: Aspose.Html.Dom.Events
Assembly: Aspose.HTML.dll (25.2.0)

The Aspose.Html.Dom.Events.IEventListener interface is the primary method for handling events. Users implement the Aspose.Html.Dom.Events.IEventListener interface and register their listener on an Aspose.Html.Dom.EventTarget using the Aspose.Html.Dom.EventTarget.AddEventListener(System.String,Aspose.Html.Dom.Events.DOMEventHandler,System.Boolean) method. The users should also remove their Aspose.Html.Dom.Events.IEventListener from its Aspose.Html.Dom.EventTarget after they have completed using the listener.

[ComVisible(true)]
[DOMName("EventListener")]
[DOMObject]
public interface IEventListener

Remarks

When a Node is copied using the cloneNode method the Event Listeners attached to the source Node are not attached to the copied Node. If the user wishes the same Event Listeners to be added to the newly created copy the user must add them manually.
