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.

Preface

Using the Split Button type


Using most of the different Button Controls is similar to what we did previously; each Button can be initially configured via a series of attributes, and those attributes can be easily set or obtained at any point in the script. As we saw in the previous example, using the custom events defined by each class is equally as simple.

Two Button types that we didn't cover in the last example were the Menu Button and Split Button types, both of which are highly specialized controls not available natively under HTML.

The Menu Button displays a Menu when it is clicked, allowing us to bundle up a series of related actions into a single Button object. The Split Button is similar but its face is split into two sections—the Button itself and a drop-down that allows the Menu to be opened. We won't be looking at the Menu Button as it is simply what the Split Button has on its right-hand side.

By the end of the example, we'll have a page the same as shown in the following screenshot...
