title: using addClass or toggleClass with JQuery inside a click method does not work? bug?
body: <p>This seems very simple.. and still it does not work correctly.</p>
  
  <p>I got it working if you put the class .normal above the .hightlight.. but i don't alter
  the style here.. only the position. This does not make any sense..</p>
  
  <p>I can't seem to paste the html code in here, so i have to do it in blocks. And I enclosed
  a snapshot of all the code.</p>
  
  <p>Make sure you have an empty html page. The doctype does not matter.. I tested it on different doctypes, but it still does not work correctly.</p>
  
  <p>This is inside the style blok after the header</p>
  
  <pre><code>.highlight { color:black; background-color:yellow; }
  .normal {  color:white; background-color: blue; }
  </code></pre>
  
  <p>after this I have a script tag with a source of the latest jquery code
  <a href="http://code.jquery.com/jquery-latest.min.js" rel="nofollow">http://code.jquery.com/jquery-latest.min.js</a></p>
  
  <p>And after this a script blok and in here goes:</p>
  
  <pre><code>$(document).ready(function () {
    $('#maindiv').css('cursor', 'pointer');
    $('#maindiv').click(function () {
      //alert("click");
     // $(this).toggleClass("highlight"); //this does not work!
     // $(this).addClass('highlight'); //this does not work!
  
     // $(this).attr("class", "highlight"); //this works
     // $(this).css("background", "yellow"); this works
  
      // the javascript way to do this works also fine.
      // var element = document.getElementById('maindiv');
      // element.setAttribute("class", "highlight");
  });
  </code></pre>
  
  <p>});</p>
  
  <p>And inside the body a p tag with an idname of "maindiv" and a class "normal"</p>
  
  <p>with text click here.</p>
  
  <p>Oke, I can't wait until someone try this too.. it's crazy, because all other
  way's work. But only the .addClass and .toggleClass don't work correctly</p>
  
  <p>Because I am an new user I can't enclose the snapshot of the complete code in here,
  but you can download it at:
