36CQ Introduction to jQuery

Sign up or log in to save this to your schedule and see who's attending!

JavaScript is very important technology in web programming today, giving programmers the ability to modify HTML document structure, content and appearance, as well as react to events such as mouse clicks and keystrokes, thus providing a richer user experience than is possible with HTML alone. But the core JavaScript language is pretty light-weight, and does not provide an extensive function library. This, along with other reasons, makes programming complex behaviors and effects in JavaScript rather tedious and error-prone. To address these issues, many open-source JavaScript frameworks have appeared in recent years and have become an indispensible part of the web programmer's tool set. Of these frameworks, jQuery is the most widely used, and one of the most powerful and easy to learn.

Learning Objectives:
In this presentation, we'll see how jQuery can be used to create some stunning effects with very little code. We'll also cover the syntax of jQuery, including the use of CSS selectors to retrieve a portion of the document to perform operations upon, as well as explore the rich, extensive function set that jQuery offers. We'll cover some of the core concepts of programming with jQuery, such as launching code on document ready, programming with anonymous functions, programming Ajax calls to the server, and extensions to jQuery such as jQueryUI.
