dedecms 二级导航的实现代码

分享下dedecms导航代码，如下：

<ul id="topmenue"> <li class="first" id="mn_portal"><a href=http://www.dede58.com/a/dedejq/"/" hidefocus="true" title="Portal">网站首页<span>Portal</span></a></li> {dede:channelartlist typeid={dede:field.typeid/} <li id="mn_N5f30" onmouseover="t('{dede:field name='typeid'/}');" onmouseout="f('{dede:field name='typeid'/}');" name=http://www.dede58.com/a/dedejq/"{dede:field name='typeid'/}"> <a href=http://www.dede58.com/a/dedejq/"{dede:field name='typeurl'/}" [field:rel/] >{dede:field name='typename'/}</a> <ul id="snav" name=http://www.dede58.com/a/dedejq/"{dede:field.typeid/}"> {dede:channel type='son' noself='yes'} <li style="display:block;height:40px;margin:0;padding:0;clear:both;background:none;text-align:cnetent;line-height:40px;background:#F4FBF4;"><a href=http://www.dede58.com/a/dedejq/"[field:typelink /]" >[field:typename /]</a></li> {/dede:channel} </ul> </li> {/dede:channelartlist} </ul> <ul id="topmenue"> <li class="first" id="mn_portal"><a href=http://www.dede58.com/a/dedejq/"" hidefocus="true" title="Portal">网站首页<span>Portal</span></a></li> {dede:channelartlist typeid={dede:field.typeid/} <li id="mn_N5f30" onmouseover="t('{dede:field name='typeid'/}');" onmouseout="f('{dede:field name='typeid'/}');" name=http://www.dede58.com/a/dedejq/"{dede:field name='typeid'/}"> <a href=http://www.dede58.com/a/dedejq/"{dede:field name='typeurl'/}" [field:rel/] >{dede:field name='typename'/}</a> <ul id="snav" name=http://www.dede58.com/a/dedejq/"{dede:field.typeid/}"> {dede:channel type='son' noself='yes'} <li style="display:block;height:40px;margin:0;padding:0;clear:both;background:none;text-align:cnetent;line-height:40px;background:#F4FBF4;"><a href=http://www.dede58.com/a/dedejq/"[field:typelink /]" >[field:typename /]</a></li> {/dede:channel} </ul> </li> {/dede:channelartlist} </ul>  

2，js代码

<script type="text/javascript"> function t(id) { var dul = document.getElementsByName(id); var fu = dul[1]; fu.style.display = "block"; } function f(id) { var dul = document.getElementsByName(id); var fu = dul[0]; var lu = fu.childNodes[3]; lu.style.display = "none"; } </script> <script type="text/javascript"> function t(id) { var dul = document.getElementsByName(id); var fu = dul[1]; fu.style.display = "block"; } function f(id) { var dul = document.getElementsByName(id); var fu = dul[0]; var lu = fu.childNodes[3]; lu.style.display = "none"; } </script>
