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.

Hiding and showing elements


The basic .hide() and .show() methods, without any parameters, can be thought of as smart shorthand methods for .css('display', 'string'), where 'string' is the appropriate display value. The effect, as might be expected, is that the matched set of elements will be immediately hidden or shown with no animation.

The .hide() method sets the inline style attribute of the matched set of elements to display: none. The smart part here is that it remembers the value of the display property—typically block, inline, or inline-block—before it was changed to none. Conversely, the .show() method restores the display properties of the matched set of elements to whatever they initially were before display: none was applied.
