javascript require/include
<p>I wrote a script like that:</p>

<pre><code>NS.load = function(src) {
    var script = document.createElement("script").setAttribute("src", src);
    document.getElementsByTagName("head")[0].appendChild(script);
}
</code></pre>

<p>It loads files but I can't reach functions and variables defiened in other files. </p>

<pre><code>//js/main.js
var qux = {name: "name"};
NS.load("js/foo.js");

//js/foo.js
alert(qux.name); //undefined variable
</code></pre>

<p>But if I define qux like this:</p>

<pre><code>window.qux = {name: "name"};
</code></pre>

<p>I can reach qux variable in other modules. As far as I know all globals are already a member of window object. So why I have to define variables like this. Could you offer another method?</p>

<p>Thanks.</p>
