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. Before Paul’s talk my understanding of jQuery performance tuning was [...]]]> http://jonraasch.com/blog/10-advanced-jquery-performance-tuning-tips-from-paul-irish/feed 11 QuickFlip 2: The jQuery Flipping Plugin Made Faster and Simpler http://jonraasch.com/blog/quickflip-2-jquery-plugin http://jonraasch.com/blog/quickflip-2-jquery-plugin#comments Mon, 13 Jul 2009 21:15:45 +0000 Jon Raasch http://jonraasch.com/blog/?p=114 Download QuickFlip 2 for jQuery Read the QuickFlip documentation QuickFlip works by using an animation shortcut that is barely noticeable when flipped quickly (hence the name). 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 jQuery Video Game Remake: T&C Surf http://jonraasch.com/blog/jquery-video-game-remake-tc-surf-designs http://jonraasch.com/blog/jquery-video-game-remake-tc-surf-designs#comments Mon, 18 Aug 2008 16:21:12 +0000 Jon Raasch http://jonraasch.com/blog/jquery-video-game-remake-tc-surf-designs 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 the src attribute of any objects. The main obstacle in development was cross-browser keyboard support. Thankfully jQuery's keyboard event objects, along with a little Javascript hacking makes it work in all browsers. ]]> http://jonraasch.com/blog/jquery-video-game-remake-tc-surf-designs/feed 21 5 Performance Tuning Tricks for jQuery http://jonraasch.com/blog/5-performance-tuning-tricks-for-jquery http://jonraasch.com/blog/5-performance-tuning-tricks-for-jquery#comments Thu, 10 Jul 2008 17:20:10 +0000 Jon Raasch http://jonraasch.com/blog/5-performance-tuning-tricks-for-jquery http://jonraasch.com/blog/5-performance-tuning-tricks-for-jquery/feed 10 Too much Javascript?
