jQuery Toggle not working in IE8

Question

I have an issue with jQuery toggle not working in IE 8. It works in the other browsers as well as IE 9 and IE 10. I'm also using Bootstrap with it. 其他浏览器以及IE 9和IE 10中使用。我也正在使用Bootstrap。

Here's my sample code below. Can someone point me in the right direction? The fate of mankind rests on your answer. :-)

<script src="http://code.jquery.com/jquery-2.0.2.min.js"></script>
    <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js">
    </script>


    <script>
       $(function() {
         $('#Hiring').click(function() {
             $('.Hiring').slideToggle('fast');
             $( "#HIR" ).toggleClass( "icon-chevron-down", 07 );
             return false;
           });

        });
    </script>



    <ul class="nav nav-list">
      <li><a href="#" id="Hiring"><i class="icon-chevron-right" id="HIR">
      </i> Hiring</a>

        <div class="Hiring" style="display:none;">
            <ul class="nav nav-list">
              <li><a href="#">Sublink 1</a></li>
              <li><a href="#">Sublink 2</a></li>
              <li><a href="#">Sublink 3</a></li>
            </ul>                                         
        </div> 

      </li>
    </ul>

From the horse's mouth :

Remember that jQuery 2.0 will not run on IE 6, 7, or 8 ;
