Introduction to AJAX


AJAX (Asynchronous JavaScript and XML) is a web development method based on using a script (Javascript) to perform queries within a web page without reloading it. AJAX makes websites more interactive, offers better ergonomics and response, by allowing the modification of part of the web interface only.
The traditional web model is based on a series of successive queries and responses (the sequential navigation from one web page to another web page). AJAX allows you to change only part of the web page, which needs to be updated by creating a local HTTP query and modifying all or part of the site, based on HTTP request recovered.

Operation


The AJAX is neither a technology nor a programming language, but refers to a method for developing web pages using the following technologies:
  • HTML and CSS for presentation
  • DOM (Document Object Model) to represent objects in the web page
  • Javascript and XMLHTTPRequest object to handle queries and responses.
