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.

Creating progressindicator widgets

The progressbar widget is intended to show the progress of some process. The end goal is the max option specified when creating the widget, which defaults to 100. If we know the size of the data we are processing ahead of time, we would use the max option to reflect this end goal. However, we are sometimes faced with the scenario where we have some processing to do on the client; or, we are waiting for some backend process to complete and send a response back to the client. For example, the user has initiated a backend task using the API, and they're now waiting for a response. The bottom line is, we want to illustrate to the user that progress is being made, and we just don't know how much progress has been made.

To display the fact that progress is being made, despite not knowing how much progress, we need an indicator widget. We can write our own widget to achieve this, extending the progressbar widget, since we can reuse many components there.
