Question

我在jsp中有一个表，我将值添加到它如下

<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

}

如何设置jsp页面中的复选框

Answer 1

我假设您的命令对象具有List<Feature> features属性，并且您希望在提交表单时列表中每个Feature对象的复选框状态。你可以尝试：

<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>

在forEach中添加form：复选框
