On numerous online forums for JavaScript and DHTML, the majority of questions begin with "How do I...?" This new Cookbook provides the answers. After reading thousands of forum threads over the years, author and scripting pioneer Danny Goodman has compiled a list of problems that frequently vex scripters of various experience levels. He has now applied state-of-the-art ECMA and W3C DOM standards and used best practices to create this extensive collection of practical recipes thatcan bring your web pages to life.The JavaScript & DHTML Cookbook is all about adding value to the content of a web page. The book focuses on practical and sensible applications of scripting, rather than flying images and gratuitous color changes. For every problem Goodman addresses, there's a solution or "recipe"--a focused piece of code that web developers can insert directly into their applications. Yet, rather than just cut-and-paste code, you also get explanations of how and why the code works, so you can learn to adapt the problem-solving techniques to your designs.The recipes range from simple tasks, such as manipulating strings and validating dates in JavaScript, to entire libraries that demonstrate complex tasks, such as cross-browser positioning of HTML elements and sorting tables. This book contains over 150 recipes on the following topics: Working with interactive forms and style sheets Presenting user-friendly page navigation Creating dynamic content Producing visual effects for stationary content Positioning HTML elements Managing browser windows and multiple framesThis book is the ideal companion to O'Reilly's JavaScript: The Definitive Guide and Dynamic HTML: The Definitive Reference. If you own either of these books, the JavaScript & DHTML Cookbook is a must.
