实现DEDECMS二级导航的简单方法

导航代码

<ul id="topmenue">

<li class="first" id="mn_portal"><a href="/" 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="{dede:field name='typeid'/}">

<a href="{dede:field name='typeurl'/}" [field:rel/] >{dede:field name='typename'/}</a>

<ul id="snav" name="{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="[field:typelink /]" >[field:typename /]</a></li>

{/dede:channel}

</ul>

</li>

{/dede:channelartlist} 　

</ul>

在添加一段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>
