Query Hotshot walks you step by step through 10 projects designed to familiarise you with the jQuery library and related technologies. Each project focuses on a particular subject or section of the API, but also looks at something related, like jQuery's official templates, or an HTML5 feature like localStorage. Build your knowledge of jQuery and related technologies. Learn a large swathe of the API, up to and including jQuery 1.9, by completing the ten individual projects covered in the book. Some of the projects that we'll work through over the course of this book include a drag-and-drop puzzle game, a browser extension, a multi-file drag-and-drop uploader, an infinite scroller, a sortable table, and a heat map.
