正在使用两个div来显示数据，上面的代码不起作用。任何帮助都被接受。

作为@Zauberfisch stated here，您需要在模板中使用limit(4)（注意小写）。

另一个问题是<%和loop之间缺少空格。

假设$ Video是某种SS_List（ArrayList或DataList），你可以试试

//show the first 4 videos
<% loop $Video.limit(4) %>$Title <% end_loop %> 
//gets the next 9 videos, offset is 5
<% loop $Video.limit(9,5) %>$Title <% end_loop %>

请参阅API docs for limit

Silverstripe循环
