{% categoryDetail productCategoryTitle with name="Title" id="2" %}{# 将ID为2的分类标题赋值给productCategoryTitle变量 #}

{% categoryDetail productCategoryLink with name="Link" id="2" %}{# 将ID为2的分类链接赋值给productCategoryLink变量 #}

<p>前往 <a href="{{ productCategoryLink }}">{{ productCategoryTitle }}</a> 页面。</p>

<p>前往 <a href="{% categoryDetail with name='Link' id='2' %}">{% categoryDetail with name='Title' id='2' %}</a> 页面。</p>

call by alias (token):

{% set productCategoryTitleByToken = "" %}
