There are three major types of events which you can add event handlers
  • Form related events
  • links
  • Loading and Unloading new window
These are new attributes inside tags which traditionally respond to Mouse clicks or movement (or possibly text input)
onUnLoad event handler is called when you exit a particular page
onLoad event handler is called when you load (or reload on returning to page) a new page
  • <body onLoad='alert("You have just seen my first JavaScript Program Loaded!")' .. other body tags ... >
