Abstract:

Since the day Microsoft built support for JavaScript into Internet Explorer 3.0, Netscape's client-side language has become the de facto standard for enhancing web pages at the browser. In this full-length excerpt from Practical JavaScript Programming, author Reaz Hoque explains the basics of client-side scripting. He also gives you some neat scripts that can enhance your web pages, making them impressively interactive. Important code snippets available in this article include a browser detection script, capable of offering tailored content based on broswer version or type. For instance, it's important (unless you like crashing visitors' computers) to only serve JavaScript 1.1 code to Netscape Navigator 3.0 or later.
