Book Description

JQuery is still the most popular JavaScript library. It is used in over 60% of the top websites on the Internet. It was written to make DOM manipulation (so, moving things around a web page) easier for developers. It acts through JavaScript to ascribe HTML elements to the DOM attributes. Because it is a library of predefined functions, all you need to start using jQuery is a working knowledge of the syntax and a reference for the functions available to you.

This practical guide shows you how to make the most of jQuery to boost the performance of your websites and applications. We start off with a quick glance through the basics of JQuery, followed by the explanation of JQuery selectors, filters, and DOM element manipulation. After this, you will learn how events and animations can be used to create and design beautiful and user-friendly sites. Next, you will be familiarized with Ajax functions to help you send and receive data from your server. Finally, we'll walk you through using built-in plugins and eventually create your own plugins for your websites.

By the end of this book, you will be able to to build robust and efficient websites successfully using JQuery.
