Try:

$(function(){
    var div = $('#asd').val(); 
});

So your function will be executed when the DOM is fully loaded.

See a working example:

$(function() {
  var div = $('#asd').val();

  console.log(div);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="hidden" id="asd" value="2" />

Using jQuery it is a good habit to put all of your code inside 

$( document ).ready(function() {

});

because that prevent your code to begin before the rest of your DOM has been loaded.

So in your case your code should look like : 

$( document ).ready(function() {
   var div = $('#asd').val(); 
});
