AJAX updates the contents of a web page as follows-

  1. An event happens on the web page. This can be the user moving the mouse, clicking a button, or changing a field. Or, this can be a timer going off. This event triggers JavaScript code to execute.
  2. JavaScript prepares a request and sends it to the web server. The request contains information about the event and the current state of the controls on the web page.
  3. The server receives the data and processes it. Although processing can take place on the client, some actions, such as database access, must happen on the server.
  4. The server prepares a response and sends it back to the browser. The response contains the updated state of the controls on the web page.
  5. JavaScript parses the response and uses the data it contains to update the contents of the web page by modifying objects in the DOM. The browser then updates the users screen.
