Answer 1

jstl的foreach标签能嵌套使用，举个例子吧
<</SPAN> %

List<</SPAN> String > list = new ArrayList <</SPAN> String > ();
list.add("a");
list.add("b");
list.add("c");

List<</SPAN> String > member = new ArrayList <</SPAN> String >();
member.add("hello");
member.add("world");

request.setAttribute("list", list);

for(int i = 0 ; i <</SPAN> list.size (); i++) {
request.setAttribute("option" + i, member);
}

%>

<</SPAN> c:forEach items = "${requestScope.list}" varStatus = "status" var = "item" >
${item}的选项
<</SPAN> c:set value = "${'option'}${status.index}" var = "option" />
<</SPAN> c:forEach items = "${requestScope[option]}" var = "i" >
${i}
</</SPAN> c:forEach >

<</SPAN> br >
</</SPAN> c:forEach >
