I am working on some Javascript to run locally on my PC. I am using a jQuery CSV plugin (http://plugins.jquery.com/project/csv) to load load a csv file into javascript arrays. The script is simple:

$(function(){
 $.get("file.csv", function(data){
  stuff = $.csv()(data);
 })
})

In Firefox it works fine but in Chrome it says "Origin null is not allowed by Access-Control-Allow-Origin". What does that mean? I find all sorts of threads about cross-server stuff related to this error but I am just working with local files.

Chrome doesn't believe that there's any common relationship between any two local files.

You can start it with the option "--allow-file-access-from-files" to tell it you disagree.

Thanks to the ascendant master Nick Craver for this info when I asked essentially the same question some time ago.
