<p>
在织梦模板中调用以下代码：</p>
<blockquote>
<ol class="dp-c">
<li class="alt">
<span><span><h3><a href=</span><span class="string">"{dede:field.typeid function=getToptype(@me,typeurl)/}"</span><span>>{dede:field.typeid </span><span class="keyword">function</span><span>=getToptype(@me,typename)/}</a></h3> </span></span>
</li>
</ol>
</blockquote>
<p>
{dede:field.typeid function=getToptype(@me,typeurl)/}获取顶级栏目链接</p>
<p>
{dede:field.typeid function=getToptype(@me,typename)/}是获取顶级栏目名称。</p>
