YUI 2.8: Learning the Library

Overview of this book

The YUI Library is a set of utilities and controls written in JavaScript for building Rich Internet Applications, across all major browsers and independently of any server technology. There's a lot of functionality baked into YUI, but getting to and understanding that functionality is not for the faint of heart. This book gives you a clear picture of YUI through a step-by-step approach, packed with lots of examples.YUI 2.8: Learning the Library covers all released (non-beta) components of the YUI 2.8 Library in detail with plenty of working examples, looking at the classes that make up each component and the properties and methods that can be used. It includes a series of practical examples to reinforce how each component should/can be used, showing its use to create complex, fully featured, cross-browser, Web 2.0 user interfaces. It has been updated from its first edition with the addition of several chapters covering several new controls and enriched with lots of experience of using them.You will learn to create a number of powerful JavaScript controls that can be used straightaway in your own applications. Besides giving you a deep understanding of the YUI library, this book will expand your knowledge of object-oriented JavaScript programming, as well as strengthen your understanding of the DOM and CSS. The final chapter describes many of the tools available to assist you the developer in debugging, maintaining, and ensuring the best quality in your code. In this new edition, all the examples have been updated to use the most recent coding practices and style and new ones added to cover newer components. Since the basic documentation for the library is available online, the focus is on providing insight and experience.The authors take the reader from beginner to advanced-level YUI usage and understanding.

The last member of the menu family is the MenuBar, which creates a horizontal application-style menu bar. Like both of the other menu types, the menu bar is exceptionally easy to create and work with.

For this example, we can create a basic user interface for a web-based text editor. Creating a fully working online application that can be used to create or open .txt files is beyond the scope of this chapter, but we can at least see how easy it would be to create the interface itself. The final page will look like this:

There is not the slightest chance that this application could possibly work without JavaScript enabled so we'll dispense with using any markup. The body of the page should contain:
