User Interface Designer Question:

A DHTML application supports numerous events, many of them quite analogous to those of a standard VB application. Events are the beating heart of any JavaScript application. For handling event in DHTML we attach event handler to HTML elements. The event handler waits until a certain event, for instance a click on a link, takes place. When it happens it handles the event by executing some JavaScript code that has been defined by us. After it has executed the code the event handlers comes to its initial state and wait for the user to fire any event. Hence to handle events in DHTML we need to register an event handler.
