jax (javascript and xml) is simply "another" flashy name to describe components written using javascript and xml as it's core technologies. jaxWidgets are useful web widgets that can be implemented on any browser supporting DOM and Javascript. It is purely a client-side technology and requires no server components to work. Who is jax for? jax is aimed primarily at web designer/developers with a strong focus on minimising the programming required while still providing advanced functionality offered by javascript code. How does jax work? jax defines a set of custom tags for each widget (ASP.NET style). All the designer needs to do is include the widget code (and core components) needed through script src's tags and place the corresponding tag for the widget into a normal XHTML page. jax handles the processing of all custom tags and UI actions.
