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.

Revisiting events

For our sample document, we will create a simple photo gallery. The gallery will display a set of photos with an option to display additional photos upon the click of a link. We'll also use jQuery's event system to display textual information about each photo when the cursor is over it. The HTML that defines the gallery is as follows:

<div id="container">
  <h1>Photo Gallery</h1>

  <div id="gallery">
    <div class="photo">
      <img src="photos/skyemonroe.jpg">
      <div class="details">
        <div class="description">The Cuillin Mountains,
          Isle of Skye, Scotland.</div>
        <div class="date">12/24/2000</div>
        <div class="photographer">Alasdair Dougall</div>
    <div class="photo">
      <img src="photos/dscn1328.jpg">
      <div class="details">
        <div class="description">Mt. Ruapehu in summer</div&gt...
