Twitter bootstrap – Bootstrap Togglable tabs. How can I show the .tab-pane content when I hover over the `.nav-tabs > li`, then hide the content when the mouse leaves?

I have togglable tabs using Twitter Bootstrap. My problem is that my .tab-content is hidden and I want to show it when the mouse pointer enters the .nav-tabs > li and hide it when the mouse pointer leaves the elements.

Here is my code:

      <div role="tabpanel" class="tabpanel">
          <div class="container">
            <!-- company tabs -->
            <ul class="nav nav-tabs" role="tablist">
              <li role="presentation">
                <a href="#sigma" aria-controls="sigma" role="tab" data-toggle="tab" class="boxopacity">
                  <span>TAb1</span>
                </a>
              </li>
              <li role="presentation">
              <a href="#alpek" aria-controls="alpek" role="tab" data-toggle="tab" class="boxopacity">
                  <span>TAb2</span>
                </a>
              </li>
              <li role="presentation">
                <a href="#nemak" aria-controls="nemak" role="tab" data-toggle="tab" class="boxopacity">
                  <span>TAb3</span>
                </a>
              </li>
            </ul><!-- .end company tabs -->

            <!-- company information -->
            <div class="tab-content">
              <!-- company sigma -->
              <div role="tabpanel" class="tab-pane fade" id="sigma">
                <div class="box largebox">
                  <div class="content">
                    <h5>Tab1</h5>
                  </div>

My Jquery:

<script>
    $(document).ready(function (){
      $('.nav-tabs > li > a').hover(function () {
        $(this).tab('show');
        }, function () {
      });        
    });
  </script>
