Special Edition Using JAVASCRIPT
By Mark C. Reynolds
Five years ago the Internet was mostly the province of academics and programmers, and the World Wide Web was an obscure idea in the minds of a few researchers. Today both are experiencing explosive growth and unparalleled interest. Web pages are being created at an astonishing rate. The fundamental challenge of Web page development is that while it is easy to create a Web page, it is more difficult to create an attractive and exciting one.
HTML, the markup language that describes the appearance of a page, is easy to learn, and requires no background in programming. HTML has undergone several revisions in order to meet the expanding needs of Web page authors. However, there are limits to what can be achieved inside HTML. The Java programming language was introduced to dramatically extend the Web developer's set of tools, but is still more complex than HTML. Java is very easy to learn; however, like most programming languages, it isn't easy to master. JavaScript bridges this gap.
JavaScript offers the Web page author a new level of sophistication without requiring him to become a programmer. JavaScript brings dynamic and powerful capabilities to Web pages, yet JavaScript is no more difficult to learn than HTML. JavaScript can be used to solve common problems, such as validating forms input, and can also be used to create dramatic and visually appealing content, which would be impossible with HTML. The goal of this book is to completely explore JavaScript, from the mundane to the extraordinary. It is designed as an introduction, a reference, and a continuous source of ideas, so that you may continually improve the Web pages that you create.
