What are possible causes for differing behaviors in jsFiddle and in local context

问题

Upon invsetigating 'mu is too short's answer to this question, 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?

Note: I am not getting any javascript errors in Firefox's error console in the local context.

UPDATE: I tried grabbing the HTML from fiddle.jshell.net/ambiguous/ZEx6M/1/show/light to a local file and loading that local file in Chromium browser and I got the following errors in the javascript console:

• GET file:///css/normalize.css undefined (undefined) /css/normalize.css
• GET file:///css/result-light.css undefined (undefined) /css/result-light.css
• Resource interpreted as Script but transferred with MIME type application/empty jquery.scrollTo-1.4.2.js:-1
• Resource interpreted as Script but transferred with MIME type text/plain jquery.viewport.js:-1

I can get rid of these javascript errors by downloading the files and modifying the <script> 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.

I also tried the same process in Konqueror. Result: the script does absolutely nothing.

回答1:

Don't use separate files for CSS and javascript. Just bring everything into HTML file (using inline javascript and inline CSS) and you should be OK.

Or, run a web server locally to serve the javascript file (with the correct MIME type) and use relative paths to CSS.
