jQuery Design Patterns

By: Thodoris Greasidis

Overview of this book

jQuery is a feature-rich JavaScript library that makes HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a variety of browsers. With a combination of versatility and extensibility, jQuery has changed the way that millions of people write JavaScript. jQuery solves the problems of DOM manipulation, event detection, AJAX calls, element selection and document queries, element attribute and data management, as well as object management utilities. This book addresses these problems and shows you how to make the best of jQuery through the various design patterns available. The book starts off with a refresher to jQuery and will then take you through the different design patterns such as facade, observer, publisher/subscriber, and so on. We will also go into client-side templating techniques and libraries, as well as some plugin development patterns. Finally, we will look into some best practices that you can use to make the best of jQuery.

How it is adopted by jQuery

A very large part of the jQuery implementation is dedicated to providing simpler, shorter, and more convenient-to-use methods for things that the different JavaScript APIs already allow us to achieve, but with more lines of code and effort. By taking a look at the provided APIs of jQuery, we can distinguish some groups of related methods. This grouping can also be seen in the way in which the source code is structured, placing methods for related APIs near to each other.

Even if the word Facade does not appear in jQuery's source code, the use of this pattern can be witnessed by the way in which the related methods are defined on the exposed jQuery object. Most of the time, the related methods that form a group are implemented and defined as properties on an Object Literal and then attached to the jQuery object with a single call to the $.extend() or the $.fn.extend() method. As you might remember, from the beginning of this chapter, this matches almost exactly...
