title: JS parseInt() issue
body: <p>I know I might be doing something wrong. Can anyone please point out why I'm getting top as object??</p>
  
  <pre><code>$(document).ready(function(){
      topwithpx='0px';
      alert(topwithpx);
      topstr=topwithpx.substr(0,topwithpx.length-2);
      alert(topstr);
      top=parseInt(topstr);
      alert(top);
  });​
  </code></pre>
