AJAX for Beginners

In this post I want to cover some of the basic concepts of AJAX and provide a springboard for more advanced topics. AJAX stands for: Asynchronous JavaScript and XML. AJAX mainly uses JavaScript and XML but you don't have to use those technologies to create an AJAX application (for example you can use VB Script instead of JavaScript). The acronym AJAX has changed to Ajax.

Ajax basically is a web application that communicates with a server in the background while not interfering with the current state of a web page.






Jesse James Garrett coined the term Ajax and said an Ajax app must have the following :

• Presentation: XHTML and CSS
  
• Interact with data: Document Object Model
  
• Data manipulation and display: XML and XSLT
  
• Asynchronous communication: XMLHttpRequest
  
• Connect the technologies: JavaScript
  

The project for this blog is a basic Ajax implementation.
