Chapter 11. JavaScript
JavaScript is a lightweight, object-based scripting language. The
general-purpose core of the language has been embedded in Netscape
Navigator, Microsoft Internet Explorer, and other web browsers and
embellished for web programming with the addition of objects that
represent the web browser window and its contents. This client-side
version of JavaScript allows executable content to be included in web
pages. With JavaScript, you can move beyond static HTML to write web
pages that include programs that interact with the user, control the
browser, and dynamically create HTML content. JavaScript is the most
popular scripting language for client-side web development.
This
chapter starts with coverage of the core JavaScript language,
followed by material on client-side JavaScript, as used in web
browsers. The final portion of this chapter is a quick-reference for
the core and client-side JavaScript APIs. For complete coverage of
JavaScript, we recommend JavaScript: The Definitive
Guide, by David Flanagan (O'Reilly).
