title: jQuery scrollTop equivalent in Prototype?
body: <p>I have this piece of jQuery code:</p>
  
  <pre><code>var scrollTop = jQuery(window).scrollTop(); 
  </code></pre>
  
  <p>How do I have to rewrite it for Prototype? I tried $$(window).scrollTop and $(window).scrollTop, doesnt work.</p>
  
  <p>Thanks!</p>
