Learning jQuery - Fourth Edition

By: Karl Swedberg, Jonathan Chaffer

Overview of this book

To build interesting, interactive sites, developers are turning to JavaScript libraries such as jQuery to automate common tasks and simplify complicated ones. Because many web developers have more experience with HTML and CSS than with JavaScript, the library's design lends itself to a quick start for designers with little programming experience. Experienced programmers will also be aided by its conceptual consistency. LearningjQuery - Fourth Edition is revised and updated version of jQuery. You will learn the basics of jQuery for adding interactions and animations to your pages. Even if previous attempts at writing JavaScript have left you baffled, this book will guide you past the pitfalls associated with AJAX, events, effects, and advanced JavaScript language features. Starting with an introduction to jQuery, you will first be shown how to write a functioning jQuery program in just three lines of code. Learn how to add impact to your actions through a set of simple visual effects and to create, copy, reassemble, and embellish content using jQuery's DOM modification methods. The book will take you through many detailed, real-world examples, and even equip you to extend the jQuery library itself with your own plug-ins.

Using HTML5 custom data attributes

So far, we've been relying on the content within the table cells to determine the sort order. While we've managed to sort the rows correctly by manipulating that content, we can make our code more efficient by outputting more HTML from the server in the form of HTML5 data-* attributes. The second table in our example page includes these attributes:

<table id="t-2" class="sortable">
      <th data-sort='{"key":"title"}'>Title</th>
      <th data-sort='{"key":"authors"}'>Author(s)</th>
      <th data-sort='{"key":"publishedYM"}'>Publish Date</th>
      <th data-sort='{"key":"price"}'>Price</th>
    <tr data-book='{"img":"2862_OS.jpg",
      "title":"DRUPAL 7","authors":"MERCER DAVID","published":"September 2010","price":44.99,"publishedYM":"2010-09"}'>
