Chapter 15. Scripting Documents

Client-side JavaScript exists to turn static HTML documents into interactive web applications. Scripting the content of web pages is the raison d'être of JavaScript. This chapter—the most important in Part II —explains how to do this.

Every web browser window (or frame) displays an HTML document. The Window object that represents that window has a document property that refers to a Document object. This Document object is the subject of this chapter, which begins by studying properties and methods of the Document object itself. These are interesting, but they are only the beginning.
