What are DOM Events?

Events are captured by event handlers. The event handler trigger the code specified to execute.

Event handlers handels events on diffrent DOM objects, and are represented by an attributes. The onload attribute represents the the onload handler, and the onload handler handels load events on the window object.

Event handler attributes prepend the letters "on" to the event name; thus an event handler attribute for a load event is written as onload.

In window.onload, for example, the load event of the window object is captured by the event handler thru it's onload attribute. The onload attribute then represents the the event handler for a load event on the window object.

You can assign code to be executed when the event handler is triggerd. A simple example would be the predefined window.alert() method to execute it's code when the onload event handler is triggered by a load event.
