What is AJAX

What is AJAX

• AJAX is a technique for accessing web servers from a web page.

• AJAX stands for Asynchronous JavaScript And XML.

• It can

  • Read data from a web server - after a web page has loaded
  • Update a web page without reloading the page
  • Send data to a web server - in the background

• 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)
