Learning Ext JS

By: Colin Ramsay, Shea Frederick, Steve 'Cutter' Blades

Overview of this book

<p>As more and more of our work is done through a web browser, and more businesses build web rather than desktop applications, users want web applications that look and feel like desktop applications. Ext JS is a JavaScript library that makes it (relatively) easy to create desktop-style user interfaces in a web application, including multiple windows, toolbars, drop-down menus, dialog boxes, and much more. Both Commercial and Open Source licenses are available for Ext JS.<br /><br />Ext JS has the unique advantage of being the only client-side UI library that also works as an application development library. Learning Ext JS will help you create rich, dynamic, and AJAX-enabled web applications that look good and perform beyond the expectations of your users.<br /><br />From the building blocks of the application layout, to complex dynamic Grids and Forms, this book will guide you through the basics of using Ext JS, giving you the knowledge required to create rich user experiences beyond typical web interfaces. It will also provide you with the tools you need to use AJAX, by consuming server-side data directly into the many interfaces of the Ext JS component library.</p>

Multiple effects

Most of the time, you'll use effects one at a time on different elements to achieve the look you're after, but in some circumstances, it can be useful to use multiple effects. There are a few different ways of handling this scenario, and in the next few sections, we're going to review these ways. We're also going to see how we can influence any running effects from our code.

Chaining

An easy way to set up a second effect to run after your first is completed, is to use method chaining. Because each of the main Ext.Fx methods returns the Ext.Element that was the target of the effect, you can then call further Ext.Element methods, including those provided by Ext.Fx:

Ext.get('target').slideIn().highlight();

As you can see from this example, we're calling slideIn followed by highlight, which indicates that highlight will be added to the effects queue to run after slideIn completes.

Queuing

Queuing is the default behavior for effects set up either...
