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.

Getting range values

The slider widget can be used to control a range value. So instead of moving a fixed point, that is the handle, back and forth over the slider axis, the user will move two handles back and forth. The space in between these two points represents the range value. But how do we go about computing that number? The slider widget gives us the raw data, the upper and lower bounds on the user selection. We can use these values inside our event handlers to compute the range value.

Getting ready...

We'll use just a basic slider for this demonstration, but we'll need some supporting CSS and HTML surrounding the slider so that we can display the range values as they're changed. Here is the CSS:

.slider-container { 
    width: 180px;
    margin: 20px;

.slider-container .slider-label {
    margin-bottom: 10px;
    font-size: 1.2em;

And here is the HTML:

<div class="slider-container">
    <div class="slider-label">
        <span>Range Value: </span>
