Question

大家好我的会话中有一个对象，我想根据我的对象的属性选择一个输入类型的无线电我尝试了struts 2 taglib的if标签，但它不起作用。这是我的代码的一部分

  <div class="form-group">
            <label class="col-sm-2 control-label">Admin </label> <label
                class="radio-inline">
                <div class="choice">
                    <s:if test="%{#session.curentprofil.isAdmin == N}">
                        <span><input type="radio" name="isAdmin" id="isAdmin"
                            class="styled" value="O" /></span>
                    </s:if>
                </div> O
            </label> <label class="radio-inline"> <span><input
                    type="radio" name="isAdmin" id="isAdmin" checked="checked"
                    class="styled" value="N" /></span> N
            </label>
        </div>
        <div class="form-group">
            <label class="col-sm-2 control-label">Admin </label> <label
                class="radio-inline">

试试这个：

<s:if test="#session.curentprofil.isAdmin == \"N\"">
   <!-- your code here -->
</s:if>
