Early chapters cover language basics, such as data types, functions, conditions and loops, string handling, and programming with objects. The authors explain how to control the Web browser by programming its object model, and how to combine scripts with forms. There is a guide to debugging with Netscape and Microsoft Internet Explorer, and a chapter on using cookies to store user preferences.

A substantial part of the book is focused on Dynamic HTML and how to write scripts that control the content of the page. There is a clear explanation of the DOM (document object model), as specified by the W3C Web standards group. Finally, there is a look at extending browser capabilities with ActiveX controls or plug-ins, and server-side scripting with Active Server Pages, including database access. Several appendixes offer a language reference and object models for Internet Explorer and Netscape Navigator 4.0. Sadly Netscape 6.0 is not covered, but it is not quite as bad as it sounds since Netscape 6.0 closely follows the official DOM. --Tim Anderson
