判断是否有子栏目，有就输出 javascript:; ，没有子栏目就直接输出一级栏目的链接
{dede:field name=typeid runphp=yes}global $dsql;$row = $dsql->GetOne("select * from `dede_arctype` where reid='@me' and ishidden<>1 order by sortrank asc limit 0,1");if(is_array($row)) @me = 'javascript:;'; else @me = GetOneTypeUrlA($dsql->GetOne("select * from `dede_arctype` where id='@me' and ishidden<>1"));{/dede:field}
演示
{dede:channelartlist row=7 typeid=top currentstyle=current}
<li>
<a href="{dede:field name=typeid runphp=yes}global $dsql;$row = $dsql->GetOne("select * from `dede_arctype` where reid='@me' and ishidden<>1 order by sortrank asc limit 0,1");if(is_array($row)) @me = 'javascript:;'; else @me = GetOneTypeUrlA($dsql->GetOne("select * from `dede_arctype` where id='@me' and ishidden<>1"));{/dede:field}"><span>{dede:field.typename/}</span>{dede:channel type='son' row=1 noself='yes'}<i class="touch-arrow-down"></i>{/dede:channel}</a>
{dede:channel type='son' row=1 noself='yes'}
<ul>
{/dede:channel}
{dede:channel type='son' noself='yes'}
<li><a href="[field:typelink/]"><span>[field:typename/]</span></a></li>
{/dede:channel}
{dede:channel type='son' row=1 noself='yes'}
</ul>
{/dede:channel}
</li>
{/dede:channelartlist}
结果
