垂直制表符不起作用

Question

我創建了一個垂直選項卡，但是它不起作用。 我找不到問題所在。

HTML：

<ul id="sidemenu">
  <li>
    <a href="#home-content" class="open"><i class="icon-home icon-large"></i><strong>Home</strong></a>
  </li>

  <li>
    <a href="#about-content"><i class="icon-info-sign icon-large"></i><strong>About</strong></a>
  </li>

  <li>
    <a href="#ideas-content"><i class="icon-lightbulb icon-large"></i><strong>Ideas</strong></a>
  </li>

  <li>
    <a href="#contact-content"><i class="icon-envelope icon-large"></i><strong>Contact</strong></a>
  </li>
</ul>
<div id="content">
    <div id="home-content" class="contentblock">
      <h1>The Main Page!</h1>
      <p>I swear this has some really great stuff. Content is courtesy of <a href="http://bluthipsum.com/">Bluth Ipsum</a>.</p>

      <p>Smack of ham. What is she doing at a beauty pageant? Is she running the lights or something? She's always got to wedge herself in the middle of us so that she can control everything. Yeah. Mom's awesome.</p>

      <p>Probably out there without a flipper, swimming around in a circle, freaking out his whole family.</p>

      <p>Fun and failure both start out the same way.</p>
    </div><!-- @end #home-content -->


    <div id="about-content" class="contentblock hidden">
      ...
    </div><!-- @end #about-content -->

    <div id="ideas-content" class="contentblock hidden">
      ...
    </div><!-- @end #ideas-content -->

    <div id="contact-content" class="contentblock hidden">
      ...
    </div><!-- @end #contact-content -->
</div><!-- @end #content -->

.contentblock {

.contentblock.hidden {
  display: none;

/* side navigation */
#sidemenu {
  margin: 0;
  padding: 0;
  width: 80px;
  float: left;
  background: #e8e8e8;
  border-right: 1px solid #c9c9c9;
}


#sidemenu li { display: block; text-align: center; border-top: 1px solid #fff; font-size: 1.1em; }

#sidemenu li a { 
  display: block;
  padding: 6px 2px;
  color: #555;
  text-decoration: none;
  border-bottom: 1px solid #d1d1d1;

}
#sidemenu li a:hover {
  background: #f2f2f2;
}

#sidemenu li a strong { 
  display: block;
  margin-top: 5px;
}

#sidemenu li a.open {
  width: 101%;
  background: #fff;
}

JQUERY：

$(function(){
  $('#sidemenu a').on('click', function(e){
    e.preventDefault();

    if($(this).hasClass('open')) {
      // do nothing because the link is already open
    } else {
      var oldcontent = $('#sidemenu a.open').attr('href');
      var newcontent = $(this).attr('href');

      $(oldcontent).fadeOut('fast', function(){
        $(newcontent).fadeIn().removeClass('hidden');
        $(oldcontent).addClass('hidden');
      });


      $('#sidemenu a').removeClass('open');
      $(this).addClass('open');
    }
  });
});

問題是，當單擊選項卡上的內容時，該選項卡的內容不顯示，只是URL被更改。

這是演示 。

在我將jQuery庫添加到您的jsFiddle之后，它運行良好
