Learning jQuery, Third 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.Learning jQuery Third Edition is revised and updated for version 1.6 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 step you through many detailed, real-world examples, and even equip you to extend the jQuery library itself with your own plug-ins.

Summary


The abilities we've discussed in this chapter allow us to:

  • Use the .ready() method to let multiple JavaScript libraries coexist on a single page with .noConflict()

  • React to a user's click on a page element with mouse event handlers and the .bind() and .click() methods

  • Observe event context to perform different actions depending on the element clicked, even when the handler is bound to several elements

  • Alternately expand and collapse a page element by using .toggle()

  • Highlight elements under the mouse cursor by using .hover()

  • Influence event propagation and default actions to determine which elements get to respond to an event by using .stopPropagation() and .preventDefault()

  • Implement event delegation to reduce the number of bound event handlers necessary on a page

  • Call .unbind() to remove an event handler we're finished with

  • Segregate related event handlers with event namespacing so they can be acted on as a group

  • Cause bound event handlers to execute with .trigger()

  • Use keyboard event...
