jQuery's getScript - including files into the main scope?

Question

I have thought a lot about how I should include files in my backbone.js-application. In production, I am obviously going to join my files and minimize them to keep requests at a minimum, but during development, it would be nice to just have all files loaded and not having to call a buildscript for every little change.

So I have taken a look at jQuery's getScript()-method. I tried it out and were able to load my files.

As I've put the getScript-call into a function, to ensure that files are loaded before I initiate my backbone.js application, it appears that every script loaded, are not included into the global scope.

var loader = function () {
     var scripts = ['/app/routers/myrouter.js'];

     for (var i = 0; i < scripts.length; i++) {
         $.getScript(scripts[i], function () {});
     }

     console.log(myrouter); // Works - myrouter is a function
     init(); // Callback - we've loaded all scripts
 };

var init = function () {
    console.log(myrouter); // myrouter is undefined
};

$(document).ready(loader());
