Overview of this book

jQuery is awesome for designers ñ it builds easily on the CSS and HTML you already know and allows you to create impressive effects with just a few lines of code. However, without a background in programming, JavaScript ñ on which jQuery is built ñ can feel intimidating and impossible to grasp. This book will show you how simple it can be to learn the basics and then extend your capabilities by taking advantage of jQuery plugins.jQuery for Designers offers approachable lessons for designers with little or no background in JavaScript. The book begins by introducing the jQuery library and a small and simple introduction to JavaScript. Then you'll step through a few simple tasks to get your feet wet before diving into using plugins to quickly and simply add complex effects with just a few lines of code.You'll be surprised at how far you can get with JavaScript when you start with the power of the jQuery library and this book will show you how. We'll cover common interface widgets and effects such as tabbed interfaces, custom tooltips, and custom scrollbars. You'll learn how to create an animated navigation menu and how to add simple AJAX effects to enhance your site visitors' experience. Then we'll wrap up with interactive data grids which make sorting and searching data easy.

        buttonNextHTML: null,
        buttonPrevHTML: null,
        initCallback: carouselInit
      });
    });

    Whatever actions we write inside of our carouselInit() function, it will be executed when the carousel is initialized or set up. Since any page numbers and previous and next buttons would only be functional if JavaScript is enabled, we want to create those buttons dynamically with JavaScript rather than coding them in our HTML.
