Definitions for "Event handler"
An event handler is a JavaScript attribute that associates an object with an event. Events are actions that take place in a document, usually as a result of user activity, such as clicking on a button. Other events, such as loading a document, may not be as obvious. In order to allow us to define JavaScript event handlers as part of HTML object definitions, JavaScript extends HTML by adding new attributes to HTML tags. For example, note the onClick event handler in this FORM: FORM INPUT TYPE="button" VALUE="Click for the Date and Time" onClick="timer( )" /FORM The lowercase on as a prefix for the event, in this case Click, is the convention for identifying event handlers even though HTML is case insensitive. Event handlers include: onAbort onBlur onChange onClick onError onFocus onLoad onMouseOver onMouseOut onSelect onSubmit onUnload A good discussion of Event Handlers can be found in the book Practical JavaScript Programming by Reaz Hoque. The chapter on event handlers is on line.
