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 [...]]]> http://jonraasch.com/blog/jquery-contra-plugin/feed 3 Appending Style Nodes with Javascript http://jonraasch.com/blog/javascript-style-node http://jonraasch.com/blog/javascript-style-node#comments Tue, 22 Dec 2009 15:00:47 +0000 Jon Raasch http://jonraasch.com/blog/?p=456

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 [...]]]> http://jonraasch.com/blog/javascript-style-node/feed 3 TranslateThis – A Javascript Translation Widget for Noobs and Nerds Alike http://jonraasch.com/blog/javascript-translation-widget http://jonraasch.com/blog/javascript-translation-widget#comments Tue, 08 Dec 2009 23:16:38 +0000 Jon Raasch http://jonraasch.com/blog/?p=411 TranslateThis is a new Javascript widget that provides 52 languages of translation by leveraging the Google Language API.

There were a lot of good speakers at today’s jQuery Summit, but Paul Irish‘s talk on jQuery Anti-Patterns for Performance & Compression was my stand-out favorite. Covering a number of advanced jQuery performance optimization techniques, this speech put my knowledge of jQuery optimization to shame.

This shortcut improves performance while allowing the flip effect to work smoothly with any piece of markup regardless of images, backgrounds or CSS. It provides an attractive alternative to other slower and more resource heavy Flash and jQuery flip animations. However if you want a smoother option with a depth effect try jQuery Flip!, although this only works with background colors (not images) and hides the panel content before flipping.]]> http://jonraasch.com/blog/quickflip-2-jquery-plugin/feed 70 Scrolling Parallax: A jQuery Plugin http://jonraasch.com/blog/scrolling-parallax-jquery-plugin http://jonraasch.com/blog/scrolling-parallax-jquery-plugin#comments Tue, 02 Jun 2009 16:55:25 +0000 Jon Raasch http://jonraasch.com/blog/?p=59 parallax effect to the scrollbars and mouse wheel. This allows a background image or anything else to scroll at a different pace than the web page when a user scrolls around. The parallax effect that results is an easy way to create an illusion of depth on your website. Basic use of the Scrolling Parallax plugin is extremely easy. Simply pass the path to an image, and the plugin takes the image and stretches it to the window width and 150% of the height. The extra 50% of the height is scrolled down along with the document, smoothly reaching the end at the same time as the page. The Scrolling Parallax plugin is also very versatile. There are a wide variety of options including scrolling faster, slower, looping and reversing the animation and tiling the background to name a few. Addtionally you can attach the parallax to any piece of markup, as well as pass an image path as described above.]]> http://jonraasch.com/blog/scrolling-parallax-jquery-plugin/feed 14 Contact-Pop: Contact Form Overlays with a Simple jQuery Plugin http://jonraasch.com/blog/contact-pop-jquery-plugin http://jonraasch.com/blog/contact-pop-jquery-plugin#comments Thu, 07 May 2009 15:52:46 +0000 Jon Raasch http://jonraasch.com/blog/contact-pop-jquery-plugin http://jonraasch.com/blog/contact-pop-jquery-plugin/feed 49
