EL表达式两个foreach嵌套循环

集合List中加List泛型的泛型

List riskEvaSuitQuestionList = riskEvaSuitQuestionService.getQueList(1000036L);
model.addAttribute("riskEvaSuitQuestionList",riskEvaSuitQuestionList);

List riskEvaSelectItemList;
List> riskEvaSelectItemLists = new ArrayList<>(); //双重泛型的构建
for (int i = 0; i < riskEvaSuitQuestionList.size(); i++) {
    riskEvaSelectItemList = riskEvaSelectItemService.getByQuestionId(riskEvaSuitQuestionList.get(i).getQuestionId());
    riskEvaSelectItemLists.add(riskEvaSelectItemList);
}
 model.addAttribute("riskEvaSelectItemLists", riskEvaSelectItemLists);

两个foreach可以直接像if一样嵌套用：

下面是一开始以为foreach不能嵌套出现的方法（看起来就头疼）：

"${riskEvaSuitQuestionList}" var="item" varStatus="i">   //第一个foreach
   "font-size: 15px;">${i.count}.${item.content}
   "margin-right: 50px;">
   "1" end="${riskEvaSelectItemLists.get(i.count-1).size()}"   varStatus="j" step="1">   //第二个foreach
     "margin-left: 50px;margin-right: 40px;" name="itemContent${i.count-1}" type="radio" value="${riskEvaSelectItemLists.get(i.count-1).get(j.count-1).itemScore}">
     ${riskEvaSelectItemLists.get(i.count-1).get(j.count-1).itemContent}

注意：JavaScript中默认加分默认为字符串相加，必须转换为parseInt()

           往input标签中写值，直接定位该标签，然后.value = 值

           javascript中也可以应用域对象取值
