Overview of this book

jQuery UI is the quintessential framework for creating professional user interfaces. While jQuery core lays the foundation for interaction with the DOM and handling events, jQuery UI fills in the user interaction gap. This book will give you a huge productivity boost out of the box with jQuery UI, and help you understand the framework, inside and out."jQuery UI Cookbook" provides you with practical recipes featuring in-depth coverage of every widget in the framework, including how to address limitations that impact your everyday development activities with these widgets. You'll get a better idea of the big picture – how the framework is composed, how the widgets relate to one another, and how to build on those patterns.Be it a minor tweak on the visual design of a progress bar or a fundamental change in a widget to meet your needs, "jQuery UI Cookbook" covers scenarios both big and small. You can show reminders as tooltips, apply a variety of effects to the menu widget, and start interactions between the dialog widget and API data using deferred objects. These and many more interesting tasks are covered in this book, which can be done with smooth learning and great understanding. You will see how button widgets can fill the width of their containing element, making the layout more consistent. Tabs can be sorted and moved between widgets. You will learn how to do all these things within the context of the big picture, by finding out why the components work the way they do, making you well-versed in jQuery UI.

Using states to warn about thresholds

The progressbar widget isn't restricted to marking the progression toward some end point. It can also be used as a marker for utilization of some resource. For example, your application might allow the user to store 100 MB worth of image data. It might make sense to show them how much of this capacity is currently in use. The progressbar widget is an ideal solution for graphically depicting resource utilization scenarios such as these. Taking things a step further, we might also want to warn the user about utilization thresholds. That is, at a certain percentage, the resource is getting near capacity, but the user still has time to do something about it.

Getting ready

For this demonstration, we will create two simple div elements for the two progressbar widgets we want to display:

<div id="cpu-utilization"></div>
<div id="memory-utilization"></div>
