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.
