100+ Practical jQuery Recipes for Solving Your Real-World Web and Mobile Development Challenges!

jQuery makes it easier than ever for developers to build exceptionally robust, cross-platform websites and mobile apps. jQuery, jQuery UI, and jQuery Mobile: Recipes and Examples is a practical “cookbook,” packed with realistic, easy-to-use solutions for making the most of jQuery Core, jQuery UI, plugins, and jQuery Mobile.

This guide brings together more than one hundred self-contained, downloadable examples, each with an in-depth explanation of how the code works and how to adapt it for your own needs. Pioneering web/mobile developers Adriaan de Jonge and Phil Dutson present examples you can apply immediately in virtually any web or mobile app, and with any server-side platform, including PHP, .NET, Java, Ruby, Node.js, or Python. This extremely useful guide will help you

Test browser support and provide for graceful degradation
Fine-tune DOM element selection and manipulate your site’s DOM structure
Master the newest techniques for event handling and binding
Communicate with web servers: AJAX, page errors, redirects, XML, and more
Use advanced UI widgets, from accordions and autocomplete to sliders and tabs
Build mobile-optimized sites with the jQuery Mobile library
Write and smoothly incorporate new plugins
Integrate powerful third-party plugins, such as the Twitter Bootstrap framework

The authors’ proven “code first, explain later” approach supports developers at all levels who want to start experimenting immediately. Their exceptionally readable examples never take shortcuts or compromise quality,and their detailed walk-throughs are ideal for anyone who wants to thoroughly understand their code. If you have a working knowledge of HTML, CSS, and basic JavaScript, you’ll feel right at home immediately; if not, de Jonge and Dutson’s careful explanations and full HTML page layout examples will get you up to speed quickly.
