What is Ajax?
Ajax is like the materials that go into making a high-rise building. High rises are made of steel instead of wood, and their exteriors are modern and flashy with metals and special glass. The basic structure is still there, walls run parallel and perpendicular to one another at 90-degree angles, and all the structure's basic elements, including plumbing, electricity, and lighting, are the same - just enhanced.
The structure of an Ajax application is built on an underlying structure of XHTML, which is an extension of HTML. Tools used to build Ajax web applications include:
- Extensible HyperText Markup Language (XHTML)
- Document Object Model (DOM)
- Cascading Style Sheets (CSS)
- Extensible Markup Language (XML)
