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