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.

A word on Sam

Completely separate from the CSS Tools, but still composed entirely of CSS, the Sam skin provides a default theme for each of the library's controls. Each control contains a skin CSS file in its assets folder and should be linked to using the standard <link> tag in the <head> of any pages on which the controls are displayed.

In order to use the skin files, as well as linking to the stylesheet used by the skin, you will also need to give the containing element (whether that is the <body> or a <div>) a special class name:

<body class="yui-skin-sam">

Or, for finer control:

<div class="yui-skin-sam">
<div id="someControl"></div>
</div>

This makes using the skin extremely easy. The Sam skin takes its name from its creator Sam Lind. At its launch, it was expected that developers would contribute further skins but that has not yet happened as each site develops the skins for the components it uses instead of a whole set for all...
