April 08 Meeting - jQuery Basics pt2

A whole component of the jQuery library is dedicated to the detection and reaction of standard browser events which are likely to occur frequently (during every visit to our page) when visitors view our pages.

One event that is used almost every time the jQuery library is engaged is the ready event. This can be used with the $(document).ready(function(){});. This will execute the code within its curly braces when the document is ready (once the page has finished loading minus images).

March 08 Meeting - jQuery Basics pt1

A relative latecomer to this world of JavaScript libraries, jQuery has taken the web development community by storm, quickly winning the support of major websites such as MSNBC, Google Code, and well-regarded open source projects including SourceForge, Trac, and Drupal.

Compared with other toolkits that focus heavily on clever JavaScript techniques, jQuery aims to change the way that web developers think about creating rich functionality in their pages.

ActionScript 3.0: Events

Events are things that happen that Flash can recognize and respond to. A mouse click is an event, as are mouse movements and keypresses on the keyboard. Events can also be things that the user doesn't initiate. The completion of a sound, for example, is an event.

Anytime an event happens, an object of the Event class is created. When the mouse button is clicked, a MouseEvent object (a subclass of the Event class) is created. When a key on the keyboard is pressed, a KeyboardEvent object (another subclass of the Event class) is created. It may seem a little strange that an object represents an event, but remember Flash objects can be very abstract.

With all these events happening, you need a way to detect and respond to them. You detect an event by creating an event listener (or event handler).

ActionScript 3.0: Display List

The key to successful manipulating graphics on the Stage is to understand what is known as the display list. The display list is the hierarchy of visible objects on the Stage. The display list lets Flash keep track of what the user sees, the visual relationships between objects, and the stacking order (or overlapping) of the objects.

Conceptually, it's much like the folder structure on your computer desktop, and can be represented as a tree structure. The top-level element is the Stage. Each time you play a Flash movie in a Web browser, the Flash Player opens your SWF and places it on the Stage. So the Stage is the container that holds your main SWF.

December 07 Meeting - script.aculo.us Library Basics

Animation effect can reinforce a message, clarify a user interaction, and even entertain. But they can just as easily cloud the interaction , distract the user, and annoy your visitors. Properly utilized, animation effects should emphasize the message of the site, clarify or reinforce the user interaction, or mildly entertain.

The script.aculo.us library is built on top of Prototype (discussed last meeting) and can create cool effects, allow for drag and drop, assist in Ajax development as well as provide DOM utilities. It is used by many commercial web sites such as Apple, Digg, Feedburner, Gucci and more.

Though just like many other libraries, be aware of the resources it will require and the real necessity of using them.

Have a safe and happy holiday and I'll see ya next year!
