Flipbook Movies with jQuery

Flipbook plugin for jQuery

Flipbook is a jQuery plugin that produces a movie effect by running images in quick succession. The concept is similar to something I always did in middle school: doodling in the margins of my notebooks to make short movies. Times have changed and nowadays I use a Javascript object, pulling the images dynamically with jQuery’s AJAX function and a PHP script ;) . But don’t worry, it’s just as easy to use as a real flipbook.

The jQuery Flipbook Plugin is built around my jQuery slideshow tutorial. It’s very flexible, providing great options for both new and seasoned developers alike. You can easily make anything from a short film to an image slideshow to a text viewer.


QuickFlip jQuery Plugin

Quickflip Plugin for jQuery

QuickFlip is a jQuery plugin I wrote that uses a CSS trick to cause a div, paragraph or any other piece of HTML markup to flip like a card. With a result similar to the UI animation on the iPhone, this jQuery plugin is easily integrated into your webpage to make any portion appear to flip and show its back.

When a flip occurs, the front panel is split in half with Javascript. The right and left halves slide into one another, and afterwards the opposite occurs with the back panel. While it‚Äôs not as smooth as some Flash animation, it all happens so quickly that it really looks like the panel is flipping over (more…)


jQuery Video Game Remake: T&C Surf

T&C Surf Designs

When I was seven, my all-time favorite video game was T&C Surf Designs for the 8-bit Nintendo® (NES). Feeling nostalgic this weekend, I developed a version of this old school game using jQuery and Javascript.

Up and Down to move, Left and Right to skate faster or slower, Spacebar to jump

After playing Javascript Mario Kart, I’ve been wanting to develop a classic video game with jQuery. T&C seemed like a good fit because its motion and overall simplicity are ideal for jQuery’s animation library (and it’s really fun).

I’m fairly pleased with the performance, which is vastly improved through the use of cell-based collision detection. Instead of having to check for collision every pixel, it can be checked every 32, with huge processing savings. Additionally, the use of CSS sprites greatly reduces the number of HTTP requests and the need to use … Read more…


A Simple jQuery Slideshow

Simple jQuery Slideshow Tutorial

In the interest of following jQuery’s motto of “writing less and doing more,” let’s write a simple slideshow using jQuery, JavaScript and a bit of CSS.

For starters, our main goal should be keeping the markup as clean as possible: <div id=”slideshow”> <img src=”img/img1.jpg” alt=”" class=”active” /> <img src=”img/img2.jpg” alt=”" /> <img src=”img/img3.jpg” alt=”" /> </div> Now let’s use CSS to position the images on top of each other and bring the active image to the images on top of each other and bring the active image to the top level with z-index:


5 Performance Tuning Tricks for jQuery

5 Performance Tuning Tricks for jQuery

In a recent post, I wrote that developers should better optimize their JavaScript. Well, that’s easier said than done, so I’d like to get down to the nitty-gritty and talk specifically about optimizing jQuery. Please note that this is not about performance tuning of the jQuery library, rather it is about better engineering the code we use to interact with it. If you’re not a jQuery programmer, and you have no interest in joining the fad, don’t worry—most of the concepts here apply to JavaScript and general programming as well.

1. Beware of class-only selectors

A great part about using a JavaScript library like jQuery is its selectors. But before you use them all over the place, stop to think: what are the processing costs?

Basically, jQuery defines all the elements on a page as a huge JavaScript object, … Read more…


Too much Javascript? Here comes WebKit and the new Safari

Too much Javascript?  Here comes WebKit and the new Safari

Let it not be said that I never fall victim to a web fad: AJAX, jQuery, SEO‚ÄîI was there with bells on. So when everyone started hating Flash and doing all web animation with HTML/Javascript, I jumped right on board. I thought it was just great! You didn’t have to lose any SEO, and most importantly you never had to open that awful Flash GUI.

But have you noticed? EVERYONE ELSE IS DOING IT! There’s just too much Javascript on the internet these days, and it is bringing many browsers to a halt. My MacBook is less than a year old (2.1GHz, 1GB mem) and Safari has been crashing frequently. In Firefox I can only have three or so tabs open before serious lag1. While I don’t have a super gaming computer, my computer is better than the average user’s, and I … Read more…


jQuery Animation and SEO

jQuery Animation and SEO

I put a bit of jQuery on my site, animating the links in my art portfolio section. Check it out. I really like jQuery actually, it looks nice, and its a great way to liven up a site’s visuals without using Flash and losing all that SEO.

The problem is that jQuery, which is essentially JavaScript, is also not very SEO friendly. You can use it pretty much the same way as Flash, in limited quantities where you don’t care about searchability. However, when you want to make it SEO friendly, it operates pretty similarly to AJAX. Basically, you don’t want jQuery to be the only way you access any content. Any content that is accessed with jQuery also needs to have hard links, anchor tags with the href to make the search engines happy. These anchor … Read more…
