Ajax

AJAX is a developer’s dream, because you can:

  • Update a web page without reloading the page
  • Request data from a server – after the page has loaded
  • Receive data from a server – after the page has loaded
  • Send data to a server – in the background

AJAX = Asynchronous JavaScript And XML.

AJAX is not a programming language.

AJAX just uses a combination of:

  • A browser built-in XMLHttpRequest object (to request data from a web server)
  • JavaScript and HTML DOM (to display or use the data)

AJAX allows web pages to be updated asynchronously by exchanging data with a web server behind the scenes. This means that it is possible to update parts of a web page, without reloading the whole page.
