在 forEach 中添加 form:checkbox

发布于 2024-12-12 17:20:22 字数 766 浏览 2 评论 0原文

我在 jsp 中有一个表，我向其中添加了值，如下所示

<c:forEach items="${features}" var="feature">
<c:choose>
    <c:when test="${feature.present == true}">
        <c:set var="featurePresent" value="REMOVE"/>
    </c:when>
    <c:otherwise>
        <c:set var="featurePresent" value="ADD"/>
    </c:otherwise>
</c:choose>

<tr>
    <td>${feature.name}</td>
    <td>${featurePresent}</td>
    <td><form:checkbox path="" value=""/></td>
</tr>   
</c:forEach>

我正在尝试添加复选框..

我的要素类是

class Feature{
  private String name;
  private boolen present;
  private boolean checkbox

}

如何在 jsp 页面中设置复选框

原文

I have a table in a jsp and i add the value to it as follows

<c:forEach items="${features}" var="feature">
<c:choose>
    <c:when test="${feature.present == true}">
        <c:set var="featurePresent" value="REMOVE"/>
    </c:when>
    <c:otherwise>
        <c:set var="featurePresent" value="ADD"/>
    </c:otherwise>
</c:choose>

<tr>
    <td>${feature.name}</td>
    <td>${featurePresent}</td>
    <td><form:checkbox path="" value=""/></td>
</tr>   
</c:forEach>

I am trying to add the checkbox ..

My Feature class is

class Feature{
  private String name;
  private boolen present;
  private boolean checkbox

}

How can i set the checkbox in the jsp page

我假设您的命令对象有一个 List; features 属性，并且您希望在提交表单时列表中每个功能对象的复选框状态。您可以尝试：

<c:forEach items="${features}" var="feature" varStatus="i">
<c:choose>
    <c:when test="${feature.present == true}">
        <c:set var="featurePresent" value="REMOVE"/>
    </c:when>
    <c:otherwise>
        <c:set var="featurePresent" value="ADD"/>
    </c:otherwise>
</c:choose>

<tr>
    <td>${feature.name}</td>
    <td>${featurePresent}</td>
    <td><form:checkbox path="features[${i.index}].checkbox" value=""/></td>
</tr>   
</c:forEach>

I am assuming your command object has a List<Feature> features property and you want the checkbox state for each Feature object in the list when you submit the form. You may try:

<c:forEach items="${features}" var="feature" varStatus="i">
<c:choose>
    <c:when test="${feature.present == true}">
        <c:set var="featurePresent" value="REMOVE"/>
    </c:when>
    <c:otherwise>
        <c:set var="featurePresent" value="ADD"/>
    </c:otherwise>
</c:choose>

<tr>
    <td>${feature.name}</td>
    <td>${featurePresent}</td>
    <td><form:checkbox path="features[${i.index}].checkbox" value=""/></td>
</tr>   
</c:forEach>
