title: jQuery scrollTop doesn't scroll
body: <p>I'm having troubles trying scroll automatically with javascript.
  My scrolling area is the body, my js code is</p>
  
  <pre><code>$("body").animate({scrollTop: $("#myDiv").position().top)
  </code></pre>
  
  <p>but I don't get any result: no animation and no scrolling
  I also tried</p>
  
  <pre><code>$("body").scrollTop($("#myDiv").position().top);
  </code></pre>
  
  <p>and also replacing </p>
  
  <pre><code>$("body") with $(window).
  </code></pre>
  
  <p>Any hint?</p>
