c：何时未进行评估

Question

我有以下表格摘要：

<div class="form-group">
    <form:label class="pull-left" path="officeName">Office Name ${isInternational}</form:label>
    <form:errors path="officeName" class="error pull-left"></form:errors>
    <c:choose>
        <c:when test="${isInternational}">
        <form:input path="officeName" type="text" class="form-control" id="officeName" placeholder="Enter Office Name"></form:input>
        </c:when>
        <c:otherwise>
        <form:input path="officeName" type="text" class="form-control" id="officeName" placeholder="Enter Office Name" readonly="readonly" ></form:input>
        </c:otherwise>
    </c:choose>

我总是可以Office Name ${isInternational}打印适当的值，但无论表单字段是什么启用。感谢。

修改：disabled="disabled" also does not work

如果您使用的是弹簧，请考虑标签属性可能不同

readonly(false/true)

HTML Optional Attribute. Setting the value of this attribute to 'true' (without the quotes) will disable the HTML element.

我的意思是值必须为真或假，请阅读上面的链接。
