通用帝国cms默认不然写法。缺点数据多的话很卡  

  [e:loop={"select * from [!db.pre!]ecms_news where classid='$GLOBALS[navclassid]' order by rand() desc limit 10",12,24,0}]

推荐写写法：

<?php
$randnum=10; //随机数量
$randids='';
$randdh='';
for($i=1;$i<=$randnum;$i++)
{
$randids.=$randdh.rand(1,400000); //1为最小ID，100000为最大ID
$randdh=',';
}
?>
[e:loop={4,10,0,0,"id in ($randids)"}]
<li><a href="<?=$bqr['titleurl']?>"><?=$bqr['title']?></a> <span class="cdzz">
<a class="works-dynsty"><?=$bqr['chaodai']?></a> ：<a class="works-author"><?=$bqr['writer']?></a> </span></li>
[/e:loop]
