Do you talking about visual effects in Chrome while browsing the source tree? This is special effect somewhere in bundle_github.js (look for CSS class "js-slide-to").
1. You can download that JS file and look into it for concrete working example. 2. With Prototype you can set global event observer for "click" event on "a.js-slide-to" selector, then inside of event handler read URL from anchor, make some fading/rolling effect with current content wrapper, then create new content wrapper, fill it via AJAX request to URL mentioned above, and finally show it with some effect. I think event observing/delegation will be made better with the latest Prototype version (1.7). -- You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.
