}前端调用当前位置：
<a href="{:url('/')}">主页</a> >{volist name="pos" id="cate"}
<a href='{if condition="$cate['cate_attr'] eq 1"}{:url('cate/index',array('cid'=>$cate['id']))}{/if}
{if condition="$cate['cate_attr'] eq 2"}{:url('page/index',array('cid'=>$cate['id']))}{/if}
{if condition="$cate['cate_attr'] eq 3"}{$cate.link}{/if}'>{$cate.cate_name}</a> {if condition="$i neq count($pos)"}>{/if}
{/volist}文章来源：https://www.hbsjsd.cn/cates/lst/18.html 最佳答案
