大家快瞧那结冰的湖水，春风一吹冰都融化了，河里的小鱼都游出海面，在湖水中自由的游来游去，多可爱的小鱼啊！多么欢快的小鱼啊！真是让人深深的为它那可爱的摸样着迷。春风一吹过那枯黄的小草身边时，小草突然边了摸样，它从原来的枯黄变成了嫩绿，慢慢地小草从嫩绿变成了鲜绿渐渐地越变越绿，绿的让人难以相信那是小草。啊！小草我为你的样子感到是个奇迹。

2、在模板中调用实例：

02 [field:typename/]
03 <ul>
04 [field:sonchannel0]
05 <li><a rel="nofollow noopener noreferrer" href="[field:typelink/]">[field:typename/]</a></li>
06 [field:sonchannel1]

08 [field:sonchannel2]
09 <li><a rel="nofollow noopener noreferrer" href="[field:typelink/]">===[field:typename/]</a></li>
10 [field:sonchannel3]

到此这篇关于织梦dede调用四级栏目就介绍到这了。逆境，是上帝帮你淘汰竞争者的地方；要知道，你不好受，别人也不好受，你坚持不下去了，别人也一样，千万不要告诉别人你坚持不住了，那只能让别人获得坚持的信心，让竞争者看着你的面孔，失去信心，退出。胜利，属于那些有耐心的人！更多相关织梦dede调用四级栏目内容请查看相关栏目，小编编辑不易，再次感谢大家的支持！
