This is a blue js + table type tab,Part of the tag content is stored in the js array. I personally feel that this special effect is not too reasonable.Because the content output from js will cause a lot of trouble reading the content,Here you should learn a js programming method,The code needs improvement.

First take a look at the running effect screenshot:

The online demo address is as follows:

The specific code is as follows:

<meta http-equiv="content-type" content="text/html;charset=gb2312">
td, a, body {font-size:9pt;color:#000000;}
.divaround_focus {cursor:pointer;background-color:#a1acdb;border-right:solid 1px #a1acdb;border-bottom:solid 1px #333333;border-left:solid 1px #c8ceea;border-top:solid 1px #c8ceea}
.divaround_blur {cursor:pointer;background:#4d5c9f;border-right:solid 1px #eeeeee;border-bottom:solid 1px #333333;border-left:solid 1px #798acc;border-top:solid 1px #a1acdb;color:#ffffff}
.divaround_content {background-color:#a1acdb;border-right:solid 1px #888888;border-bottom:solid 1px #555555;border-left:0px;border-top:solid 1px #c8ceea;}
<script language="javascript">

for (i=0;i<document.getelementbyid ("leftbuttontable"). rows.length;i ++)
 if (document.getelementbyid ("leftbuttontable"). rows [i] .cells [0] == obj)
  document.getelementbyid ("leftbuttontable"). rows [i] .cells [0] .classname="divaround_focus";
  document.getelementbyid ("divaroundcontent"). innerhtml=aroundinfoarray [i];
