EL里面c：foreach没有评估

Question

我使用Spring MVC在JAVA项目上工作。

我想用复选框做一个表格，但是， 我定制了复选框，所以我不能使用spring的表单：复选框。

所以我尽量让AC：foreach循环，以显示我的复选框：

<c:forEach var="element" items="${targetableBars}" varStatus="status"> 
    <div class="checkboxElement"> 
     <div class="squaredOne"> 
      <input id="targetedBarIds<c:out value="$(status.index)"/>" name="targetedBarIds" type="checkbox" class="squaredInput" value="<c:out value="$(status.index)"/>" checked="checked"> 
      <label for="targetedBarIds$(status.index)"></label> 
     </div> 
     <span>$(element.name)</span> 
    </div> 
</c:forEach> 

并显示：

<div class="checkboxElement"> 
    <div class="squaredOne"> 
     <input id="targetedBarIds$(status.index)" name="targetedBarIds" type="checkbox" class="squaredInput" value="$(status.index)" checked="checked"> 
     <label for="targetedBarIds$(status.index)"></label> 
    </div> 
    <span>$(element.name)</span> 
</div> 

<div class="checkboxElement"> 
    <div class="squaredOne"> 
     <input id="targetedBarIds$(status.index)" name="targetedBarIds" type="checkbox" class="squaredInput" value="$(status.index)" checked="checked"> 
     <label for="targetedBarIds$(status.index)"></label> 
    </div> 
    <span>$(element.name)</span> 
</div> 

<div class="checkboxElement"> 
    <div class="squaredOne"> 
     <input id="targetedBarIds$(status.index)" name="targetedBarIds" type="checkbox" class="squaredInput" value="$(status.index)" checked="checked"> 
     <label for="targetedBarIds$(status.index)"></label> 
    </div> 
    <span>$(element.name)</span> 
</div> 

循环中的EL不被评估，而不是对一forEach！

我已经在web.xml中的conf读的东西：我改变了它，但没有更好：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app 
     xmlns="http://java.sun.com/xml/ns/javaee" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
     version="2.5"> 


</web-app> 

，这里是全JSP：

<%@taglib prefix="form" uri="http://www.springframework.org/tags/form"%> 
<%@page session="true"%> 
<%@page isELIgnored="false" %> 

<div class="form-header"> 
    <h1 class="title">${title}</h1> 
    <h2 class="subtitle"><span><img class="subtitleImg" src="images/edit_L.png" /> Create a news</span></h2> 
</div> 

<div class="form-body">

     <input id="fileupload" type="file" name="files[]">

<br> 
<br> 
<!-- The global progress bar --> 
<div id="progress" class="progress"> 
     <div class="progress-bar progress-bar-success"></div> 
</div> 

<script type="text/javascript" > 
    $('#date').datetimepicker({ 
      timepicker:false, 
      format:'d.m.Y' 
     }); 
</script> 
<script src="<c:url value='/resources/js/singlefileupload.js' />"></script> 

谢谢！

Answer 1

<label for="targetedBarIds$(status.index)"></label> 

难道你不想花大括号？更多${status.index}？
