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.

In this task we'll focus on getting the initial set of data in order to create the page when it first loads. We need to write our code so that the function for getting the first page of data is reusable for any page of data so that we can make use of it later on in the project.

Prepare for Lift Off

We can use the standard document ready shortcut provided by jQuery, just like we have in a number of previous projects. We can get ready by adding the following code to the infinite-scroller.js file that we create earlier:

$(function () {

    //rest of our code will go here...  

});

Engage Thrusters

First of all we can add the code that retrieves the data from YouTube. Replace the comment in the preceding snippet of code with the following:

var data = {},
    startIndex = 1;

var getUser = function () {
    return $.getJSON("http://gdata.youtube.com/feeds/api/users/tedtalksdirector?callback=?", {
        v: 2,
        alt: "json"
    }, function (user) {
        data.userdata...
