Events in Programming


Events are actions that a user takes. JavaScript features event


handlers, which respond to specific user events.


For example, the onClick event handler responds to clicks on screen.


Event handlers respond by executing functions.


Examples of HTML events:



  • When a user clicks the mouse

  • When a web page has loaded

  • When an image has been loaded

  • When the mouse moves over an element

  • When an input field is changed

  • When an HTML form is submitted

  • When a user strokes a key
