AJAX Technologies

As was already said, ajax is not a single technology but a group of technologies that work together. Some AJAX technologies are:

• CSS and HTML/XHTML
• DOM
• XML or JSON
• XMLHttpRequest
• JavaScript

CSS and HTML/XHTML

The content and style are shown with the help of these technologies. It is mostly used for showing off.

DOM

It is used to display and interact with data in real time.

XML or JSON

to move data to and from the server. JSON, or Javascript Object Notation, is similar to XML, but it is shorter and runs faster.

XMLHttpRequest

For client-server communication that doesn’t happen at the same time. For more visit next page.

JavaScript

It’s used to connect the above technologies.

It is mostly used for client-side validation when it is used on its own.
