What are possible causes for differing behaviors in jsFiddle and in local context <p>Upon invsetigating 'mu is too short's answer to <a href="http://stackoverflow.com/questions/6206985/what-can-make-jquerys-unbind-function-not-work-as-expected" title="this question">this question</a>, I noticed that I get different behaviour in jsFiddle than in my local context for the exact same script. Any clues as to why that is?</p> <p>Note: I am not getting any javascript errors in Firefox's error console in the local context.</p> <p><strong>UPDATE</strong>: I tried grabbing the HTML from <a href="http://fiddle.jshell.net/ambiguous/ZEx6M/1/show/light" rel="nofollow">fiddle.jshell.net/ambiguous/ZEx6M/1/show/light</a> to a local file and loading that local file in Chromium browser and I got the following errors in the javascript console:</p> <ul> <li><code>GET file:///css/normalize.css undefined (undefined) /css/normalize.css</code></li> <li><code>GET file:///css/result-light.css undefined (undefined) /css/result-light.css</code></li> <li><code>Resource interpreted as Script but transferred with MIME type application/empty jquery.scrollTo-1.4.2.js:-1</code></li> <li><code>Resource interpreted as Script but transferred with MIME type text/plain jquery.viewport.js:-1</code></li> </ul> <p>I can get rid of these javascript errors by downloading the files and modifying the <code>&lt;script&gt;</code> tags, but it doesn't solve the problem. The page still scrolls down to the very bottom. Also these errors appear even in the working (jsFiddle) version.</p> <p>I also tried the same process in Konqueror. Result: the script does absolutely nothing.</p>
