Move your Web applications beyond the handicap of the ubiquitous thin client architecture. Today's browsers finally support advanced client-side interactions across all objects in an HTML document. Thanks to the Document Object Model (DOM), UI designers can now create interfaces that let users manipulate data in real time while still offering the conveniences of a Web application. Author Mike Padilla shows you how to implement code that exposes robust client-side functionality that is both clean and extensible.

While the Document Object Model (DOM) is perhaps best known in its role as a foundation for working with XML, variations on the theme actually started in browsers with HTML. Now DOM has come full circle as newer browsers implement the W3C Document Object Model through client-side scripting, such as JavaScript. This article looks at the JavaScript approach to DOM and chronicles the building of a Web page to which the user can add notes and edit note content.
