javascript object reference by shortcuts
<p>I have very very valuable , so i tried to make shortcuts like this :</p>

<p>LIVE example : <a href="http://jsfiddle.net/nqeUN/" rel="nofollow">http://jsfiddle.net/nqeUN/</a></p>

<pre><code>var d = "document" ,
    t = "getElementByTagName" ,
    d = "div" ,
    oc = "onclick";
d[t](d)[0].oc = function(){
    alert("1");
}
</code></pre>

<p>but it's not working , what is the reason? i can see in Google plus api that all the objects are defined like this , as strings , how do they make it work?</p>
