title: addClass removeClass not working in IE..!
body: <p>jQuery functions addClass and removeClass do not work properly when I use them to change the appearance of a div tag in Internet Exploer (IE). However, they work fine in other browsers.</p>
  
  <p>Here is sample code to illustrate my problem:</p>
  
  <pre><code>if ($('#tdh').hasClass('current')){
      $("#u50").addClass('u59c');
      $("#u59").addClass('u59b');
      $("#u61").removeClass('u59b');
  }
  </code></pre>
  
  <p>CSS:</p>
  
  <pre class="lang-css prettyprint-override"><code>.u59b {
      background-color: #3B5998;
      color: #FFFFFF;
      font-family: Segoe UI Light;
      font-style: normal;
      font-weight: bold;
      padding-right: 13%;
      text-decoration: none;
      width: 196px;
  }
  
  .u59c {
      color: #3B5998;
      font-family: Segoe UI Light;
      font-style: normal;
      font-weight: bold;
      padding-left: 10%;
      text-decoration: none;
  }
  </code></pre>
  
  <p>HTML</p>
  
  <pre><code>            &lt;a href="Page/tdh.aspx" id="tdh" class="current"&gt;
              &lt;div id="u59" class="u59 u124-pad"&gt;
                 Title1
              &lt;/div&gt;
              &lt;/a&gt;
              &lt;a href="Page/tdh2.aspx" id="tdh2"&gt;
              &lt;div id="u63" class="u59 u59b u124-pad"&gt;
                  Title2
              &lt;/div&gt;
              &lt;/a&gt;
  </code></pre>
