Question

这是我的jstl

<c:forEach items="${parentList}" var="test">
parentId${test[0].id}--------------------savestatus=${test[1]}
<li><a href="#" class="${test.[1] eq 0 ? 'active':''}" value="${test[0].id}-${test[0].category}" id="${parent.id}" onclick="return getQuestions(this);" > 
<input type="checkbox" value="${test[0].id}">${test[0].name }</a></li> 
</c:forEach>

这是我的控制器代码

@RequestMapping("/createFeedbackform")
    public String createFeedbackform(Model uiModel, HttpServletRequest request)
    {
        String target = "createFeedback";
        String clientId = "1";
        try{
            List<Parent> parentList = 
                (List<Parent>)  serviceClientServiceImpl.getParents("Parent",Long.valueOf(clientId));
            uiModel.addAttribute("parentList", parentList); 
            List<QuestionOption> questionOptions = (List<QuestionOption> )serviceClientServiceImpl.getQuestionOptions();
            uiModel.addAttribute("questionOptions", questionOptions);
            List l=serviceClientServiceImpl.getSavedParents(clientId);
            uiModel.addAttribute("savedParents",l);
        }catch(Exception e)
        {
            e.printStackTrace();
        }
        System.out.println("TARGET:::::"+target);
        return target;
    }

这是我的服务代码

public List<Parent> getParents(String entityName,Long clientId)
    {
        List<Parent> parentsList = null;
        try
        {
            parentsList = (List<Parent>) serviceClientDaoImpl.getParents(entityName,clientId);
            System.out.println(parentsList);
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
        return parentsList;
    }

这是我的DAO代码

public List<Parent> getParents(String entityName,Long cId)
    {
        String queryString="";
        queryString="select  p,(select count(distinct cpq.pid) from ClientParentQuestion cpq where cpq.cid.id = :cid and cpq.pid=p.id) FROM "+entityName+" p WHERE p.category='default' or p.category='client' and p.cid=:cid";

        Query query=entityManagerUtil.getQuery(queryString);
        query.setParameter("cid",cId);
        return query.getResultList();
    }

当我执行以下代码时

<c:forEach items="${parentList}" var="test">
parentId${test[0].id}--------------------savestatus=${test[1]}
</c:forEach>

我得到了

parentId1--------------------savestatus=1

parentId2--------------------savestatus=1

parentId3--------------------savestatus=1

parentId4--------------------savestatus=1

parentId5--------------------savestatus=1

parentId7--------------------savestatus=1

parentId8--------------------savestatus=0

parentId9--------------------savestatus=1

parentId10--------------------savestatus=1

parentId11--------------------savestatus=0

parentId12--------------------savestatus=1

parentId13--------------------savestatus=0

parentId14--------------------savestatus=0

parentId15--------------------savestatus=0

parentId16--------------------savestatus=1

parentId17--------------------savestatus=1

parentId18--------------------savestatus=1

parentId19--------------------savestatus=0

现在我的要求是如果savestatus值为0那么我将添加css类激活其他那里不会有任何css类

所以我确实喜欢这个

<c:forEach items="${parentList}" var="test">
parentId${test[0].id}--------------------savestatus=${test[1]}
<li><a href="#" class="${test.[1] eq 0 ? 'active':''}" value="${test[0].id}-${test[0].category}"  onclick="return getQuestions(this);" > 
<input type="checkbox" value="${test[0].id}">${test[0].name }</a></li> 
</c:forEach>

但通过这样做，我得到了很多错误

任何人都可以告诉我哪里出错了吗？

Answer 1

您可能应指定test[1]而不是test.[1]
