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>

More widget wonders

Let's get back to making our little application as annoying as possible by adding an icon and buttons! This can be done by adding a style for the icon, and modifying the config to have an icon record along with a buttons record.

First, let's discuss the CSS we need. Add the following code into the head of the document, within a style tag:

.milton-icon {
background: url(milton-head-icon.png) no-repeat;
}

Also, we will make some changes to our widgets configuration. The icon record just needs our style name as the value, milton-icon. We have also included a function to be executed when a user clicks on any of the buttons in the dialog. This function is created as an anonymous function, and in this case, it is merely used to pass variables:

Ext.Msg.show({
title: 'Milton',
msg: 'Have you seen my stapler?',
buttons: {
yes: true,
no: true,
cancel: true
},
icon: 'milton-icon',
fn: function(btn) {
Ext.Msg.alert('You Clicked', btn...
