pwittchen / loadJson.js
Created Apr 19, 2014
Loading JSON file with JavaScript. Please note: it won't run as a "local" script. JavaScript does not allow to load local files due to security reasons. You should deploy it on the server in order to load JSON file.

// .open will NOT return a value
// but simply returns undefined in async mode so use a callback
