Overview of this book

jQuery is used by millions of people to write JavaScript more easily and more quickly. It has become the standard tool for web developers and designers to add dynamic, interactive elements to their sites, smoothing out browser inconsistencies and reducing costly development time.jQuery 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. Learn which jQuery methods and techniques to use in which situations with jQuery Hotshots.

Creating the script wrapper


We won't be making use of jQuery's $(document).ready() { } function (or the $(function() { }) shortcut) to execute our code when the page has loaded. However, we still need to protect our top-level variables and functions from the global scope so we still need a wrapper of some kind. In this task we'll create that wrapper, as well as our top-level variables.

Engage Thrusters

In the empty bounty-hunter.js file, we can start by adding the following code:

(function() {

    var tags = "",
          getBounties = function(page, callback) {

        $.ajax({
            url: "https://api.stackexchange.com/2.0/questions/featured",
            dataType: "jsonp",
            data: {
                page: page,
                pagesize: 10,
                tagged: tags,
                order: "desc",
                sort: "activity",
                site: "stackoverflow",
                filter: "!)4k2jB7EKv1OvDDyMLKT2zyrACssKmSCX
