Asynchronous JavaScript and XML, or Ajax, is a web development technique for creating interactive web applications using a combination of:





  • XHTML (or HTML) and CSS for marking up and styling information


  • The Document Object Model manipulated through JavaScript to dynamically display and interact with the information presented


  • The XMLHttpRequest object to exchange data asynchronously with the web server. (XML is commonly used, although any format will work, including preformatted HTML, plain text, JSON and even EBML). In some Ajax frameworks and in some situations, an IFrame object is used instead of the XMLHttpRequest object to exchange data with the web server.
