Java 在Strut2.0的迭代器中使用复选框

在我的示例应用程序中，这非常有效

<s:iterator value="menuGroup" var="menu">
                <s:textfield value="%{#menu.name}"></s:textfield>
            </s:iterator>

---

更直截了当的说法是：

<s:iterator value="menuGroup">
  <s:textfield value="name"/>
</s:iterator>

现在，由于没有提供其他信息，您是否编写了相应的（顺便说一句，这是错误的）：

因为您可以使用字符串命名和标记复选框，但值必须是布尔值，因为它指的是复选框状态，不要与等同于html复选框参数“value”的fieldValue属性混淆。见：

如果您发现标签是一种障碍，只需将复选框写为html

您就可以说“在我的示例应用程序中，它工作得很好”，但在ie中却不是这样。你的确切问题是什么，它不适用于ie，但适用于其他浏览器？我们需要查看失败的确切代码片段。在您的代码片段中，您的var是“菜单”，而不是“参数”，这就是在失败情况下var的外观。这也将有助于准确地了解您是如何尝试使用复选框的。我看到您最近编辑了您的答案，以包括一个如何使用复选框的示例。。。如果您注意到我提供的关于不做什么（因为它不起作用）的示例在功能上与您所说的您正在尝试做的相同。您正在尝试在应该使用fieldValue属性的位置使用value属性。value属性必须解析为布尔值。这段代码也给出了同样的错误谢谢你的指导最后这是完美的作品
