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.

Displaying the list of selected files


In this task we can populate the <div> we created in order to display the list of files that have been selected for upload. We'll build a table where each row in the table lists a single file with information such as the filename and type.

Engage Thrusters

Directly after the init() method in uploader.js, add the following code:

Up.prototype.handleFiles = function() {
  
    var widget = this,
          container = widget.el.find("div.up-selected"),
          row = $("<tr/>"),
          cell = $("<td/>"),
          remove = $("<a/>", {
             href: "#"
          }),
    table;

    if (!container.find("table").length) {
        table = $("<table/>");

        var header = row.clone().appendTo(table),
              strings = widget.config.strings.tableHeadings;

        $.each(strings, function(i, string) {
                var cs = string.toLowerCase().replace(/\s/g, "_"),
                      newCell = cell.clone()
