今天也算用了不少手段来实现他们的要求，大概记录一下，下边的代码示例，我全部修改贴出来，争取全部占到自己的代码里就能用。

1、点击同一个div，打开/关闭另一个div。

  1 <script type="text/javascript" src="jquery-1.11.1.min.js"></script>

  2 <script type="text/javascript">

  3     /*var btnShow=document.getElementById('show_detail');

  4     var detail=document.getElementById('detail');

  5     btnShow.onclick=function(){

  6         if(detail.style.display=="none"){

  7             detail.style.display="block"

  8         }else{

  9             detail.style.display="none";

 10

 11         }

 12

 13     }*/

 14      $(function(){

 15         $("#show_detail").click(function(){

 16             $('#detail').toggle('fast');

 17             })

 18         })

 19 </script>

然后是html代码，大概做了个简单的：

 <div class="content" style="width:400px;">

   <div id="show_detail" align="right" style="margin-right:20px; color:#00F; cursor:pointer;">[详细信息]</div>

   <div id="detail" align="left" style="display:none; height:150px; overflow:auto; padding:10px;">

     <hr />

     <br />

     <p>弹出框:</p>

     <p style="line-height:25px;">欢迎访问，有何问题欢迎交流<br />

     </p>

   </div>

   <p style='text-align:center'><b><span style='font-size:1.5em'>&raquo;</span> 返回 <a href="javascript:history.back()">上一层</a></b></p>

 </div>

隐藏部分的也可以，不过显示效果不如下边jquery写的。slow和fast是显示速度，效果还不错。

实现效果：

本想都写一个的。发现这样的话会很长，分着写吧。到时候在写一个索引便好。
