Ajax

Why Ajax

  • HTML is basically for hyperlinked documents and offers very limited interactions.
  • AJAX brings desktop like interactions to the web and complements HTML in terms of graphic user interfaces.

Ajax isn’t a technology. It’s really several technologies, each flourishing in its own right, coming together in powerful new ways. Ajax incorporates:

  • standards-based presentation using XHTML and CSS;
  • dynamic display and interaction using the Document Object Model; The structure of the DOM exposes new powerful methods which allow you access and manipulate the elements of any document.
  • data interchange and manipulation using XML and XSLT;
  • asynchronous data retrieval using XMLHttpRequest;
  • and JavaScript binding everything together. It has comprehensive control over every page element.
