jQuery Contra Plugin – Up, up, down, down, left, right, left, right, B, A, enter

jQuery Contra Plugin – Up, up, down, down, left, right, left, right, B, A, enter

Remember the code from Contra on original Nintendo? Up, up, down, down, left, right, left, right, B, A, start; it’s also known as the Konami Code and the 30 Lives Code.

This famous sequence of buttons from the 80′s isn’t going anywhere: in more recent times it’s been in a Moldy Peaches song, and used as an easter egg in Google Reader and Facebook, to name a few.

But I’m sure tons of great things can still be done with the code from Contra, so I built it into a simple jQuery plugin that can be easily used on any site.

The jQuery Contra Plugin allows you to call a function of your choice whenever a user enters the Konami Code (up, up, down, down, left, right, left, right, b, a, enter).

Appending Style Nodes with Javascript

Appending Style Nodes with Javascript

In Javascript it often makes sense to attach a stylesheet rather than style a bunch of individual attributes. Appending a stylesheet to the DOM has a number of advantages:

  • Stylesheets can be easier to work with than Javascript—it’s just more natural to use CSS syntax for styling.
  • It’s nice to avoid the cross-browser headaches associated with Javascript styling. Compare CSS’s simple float: left to Javascript’s style.styleFloat = ‘left’ and style.cssFloat = ‘left’.
  • Appending a stylesheet is better for performance when styling 15 or more elements.
  • CSS allows you to leverage pseudo-classes and define styles with the simple a:hover selector instead of both onmouseover and onmouseout event listeners.

There are a couple ways to append a stylesheet. Although it’s usually best to attach an external stylesheet, there are times when you need to build a stylesheet on the fly with Javascript. Let’s walk through the code we’ll need to append … Read more…

Book Review : Learning jQuery 1.3

Book Review : Learning jQuery 1.3

For the past couple years jQuery has been gaining in popularity, from a hot script with easy CSS selectors released by John Resig in 2006, all the way to jQuery 1.3.2, probably the most widely used Javascript library today. The jQuery core has been constantly expanding, offering new methods and performance tuning with every release, in addition to the wide variety of jQuery plugins that are released almost daily.

Known for publishing resources for the latest development trends, Packt Publishing has recently released an updated version their jQuery book: Learning jQuery 1.3, by Jonathan Chaffer and Karl Swedberg of Learning jQuery (the website). This new resource provides an excellent introduction to jQuery as well as going into detail on some of its finer topics. I’d highly recommend it for anyone who is fairly new to jQuery—it will give you a great head start in … Read more…

YouTubin’ Plugin for jQuery

YouTubin’ Plugin for jQuery

YouTubin’ is a jQuery plugin that makes embedding YouTube videos clean, easy and unobtrusive. In its simplest form, YouTubin’ grabs any links that point to a YouTube page and replaces them with an embedded video. To do so, YouTubin’ leverages SwfObject 2 if available, but otherwise just embeds the video through standard markup.

Advanced options include flagging specific video elements using a jQuery selector and setting a variety of swf properties such as dimensions, flash version, flashvars and params. Youtubin’ can even be used to cause the video to embed once a link is clicked rather than when the page loads.

A million ways to embed custom fonts (and keep typography nerds off your back)

Custom font embedding

It’s time for developers to stop complaining about web typography. Custom font embedding has been around for years, and it has finally gotten to the point that typography nerds can be equally happy with the fonts on a website as they are with the Photoshop comps. Many of the things that were a total pain to support previously have become a piece of cake. Leading, kerning, and all the major typography buzzwords have been handled for some time. Even drop shadows and Photoshop-style font rasterization options such as ‘strong’ and ‘crisp’ are now fully supportable.

So let’s make sure that we don’t become dinosaur developers, and get up on these modern methods of custom font embedding.

In this article we‚Äôll cover all types of font embedding, from older image replacement methods to embedding fonts with Flash, as well as native browser methods and even full Javascript … Read more…

10 Javascript Resources – From Noob to Pro

10 Best Javascript Resources

When I started developing I was fortunate enough to have an experienced friend who pointed me to all the right articles, websites, etc. The right tools make all the difference and this educational jumpstart was exactly what I needed to hit the ground running.

Now that I’ve gathered a good deal of Javascript knowledge and used a wide variety of Javascript resources, I’d like to share these so that others can experience the same benefit I did. And don’t stop reading if you already know Javascript inside and out: there’s resources here for all skill levels, from noob to pro.

The Mozilla Development Center should be your starting point for all things Javascript.

Beginners should start with the Core Javascript Guide. Javascript can be a really confusing language at first and going through each of these pages will make you comfortable with Javascript’s peculiar syntax … Read more…

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…)

Handy CSS Cleanup Tool

Dust-Me Selectors

Inevitably, when finishing development of a front-end, I find myself going through the painstaking process of cleaning up extraneous CSS styles. This style was for debugging, this block was for a page that got nixed, this piece I used when conceptualizing the site another way: I don’t think it’s possible to develop a website without removing some styles at the end. Dreading another round of CSS cleanup, I considered programming a tool to spider a site and tell me which parts of the stylesheets were used. It seemed a daunting task so I checked online, and sure enough, someone had already developed it, and far better than I could have. The tool I found, Dust-Me Selectors, is a Firefox extension that makes cleaning up CSS a snap. It can spider an entire site or a group of pages to determine which CSS blocks are unused … Read more…
