你是不是还有个div的id为hidden2了 但是你这里只有一个div,我已经在加了一个div id为hidden2 看看是不是你要的那种效果。

<a href="javascript:DIVShow('hidden1')">个人产品</a>

<a href="javascript:DIVShow('hidden2')">商用产品</a>

<div class="show" style="display:none" id="hidden1">

<ul class="nav_2">

<div class="jtou" style="position:relativeleft:116pxtop:-11px"></div>

<span style="float:leftcolor:#0085C3font-size:15pxfont-weight:boldheight:55pxline-height:55px">限时特惠 </span>

<li><a href="#">笔记本</a></li>

<li><a href="#">超级本</a></li>

<li><a href="#">台式机</a></li>

<li><a href="#">一体机</a></li>

<li><a href="#">Alienware游戏电脑及配件</a></li>

<li><a href="#">显示器</a></li>

</ul>

</div>

<div class="show" style="display:none" id="hidden2">asfaff</div>
