Chapter 17. Scripts

Chapter 17. Scripts

Scripts are little programs that add interactivity to your page. You can write simple scripts to add an alert box or a bit of text to your page, or more complicated scripts that load particular pages according to your visitor's browser or change a frame's background color depending on where they point the mouse. Because scripts are perfect for moving elements around on a page, they are the backbone of dynamic HTML, also known as DHTML.

Most scripts are written in JavaScript, which was developed by Netscape Communications (the same folks who created Netscape Navigator and Netscape Communicator). That's because JavaScript is the scripting language that is supported by most browsers, including Communicator and Explorer. VBScript, developed by Microsoft, currently works only with Explorer for Windows.
