As a web user, you'll no doubt have noticed some of the breathtaking applications available in today's modern web, such as Google Maps and Flickrdesktop applications than the old style web sites you are used to. You've probably also wished that you could create such things, and then thought "e;nahhh, I'd need to know a lot of complicated code to be able to even start creating sites like these."e; Well, think again.There is a lot of complicated code involved in cutting-edge "e;Ajax-style"e; web applications, but a lot of the hard work is already done for you, and available on the Web. JavaScript libraries exist to provide most of that Ajax/DOM Scripting functionality out of the box. Application programming interfaces (APIs) exist to allow you to transplant complicated applications such as Google Maps and Flickr right into your own web sites. And hosting services such as Flickr and YouTube provide all you need to store and retrieve your media (be it images, video, or whatever) at your leisure, without having to worry about bandwidth issues and file naming nightmares.All you need to know is enough to successfully wire together all this functionality successfully and responsibly, and this book shows you how. It starts from the very beginning of your journey, showing you what's available, what you need, and how to set up an effective development environment. After a solid base has been built, it shows you how to build up each aspect of your site, including storing, retrieving, and displaying content, adding images and video to your site, building effective site navigation and laying it all out beautifully using CSS, promoting your content so you will attract visitors to your site, and adding special effects to enhance usability and design asthetics...all with ready-made functionality available on the Web! Life as a web developer has never been easier.

JavaScript is one of the most important technologies on the web. It provides the means to add dynamic functionality to your web pages and serves as the backbone of Ajax-style web development. Beginning JavaScript with DOM Scripting and Ajax is an essential guide for modern JavaScript programming; it’s practical but comprehensive. It covers everything you need to know to get up to speed with JavaScript development and add dynamic enhancements to web pages and program Ajax-style applications.Experienced web developer Christian Heilmann begins gently by giving you an overview of JavaScriptits syntax, good coding practices, and the principles of DOM scripting. Then he builds up your JavaScript toolkit, covering dynamically manipulating markup, changing page styling on the fly using the CSS DOM, validating forms, dealing with images, and much more. Then he takes you to advanced territory, with a complete case study illustrating how many new JavaScript techniques can work together, plus a great introduction to Ajax development.
