Learning jQuery - Fourth Edition - Fourth Edition

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.

  • An object of style properties and values, which is similar to the .css() argument discussed earlier in this chapter

  • An optional duration, which can be one of the preset strings or a number of milliseconds

  • An optional easing type, which is an option that we will not use now, but which we will discuss in it in Chapter 11, Advanced Effects

  • An optional callback function, which will be discussed later in this chapter

All together, the four arguments look like this:

.animate({property1: 'value1', property2: 'value2'}, 
duration, easing, function() {
    alert('The animation is finished.');

The second form takes two arguments: an object of properties and an object of options:

.animate({properties}, {options})

In effect, the second...
