Question

我希望我的代码能够做到这一点......

<c:if test="${validated != 'Y' }">
    <form:form id="newJob" method="post" action="updateValidated" commandName="jobModel">
        <form:input path="regattaId" type="hidden" />
        <form:input path="job_id" type="hidden" />
        <table>
            <tr>
                <td><spring:message code="label.validated" />
                <td><form:radiobutton path="validated" value="Y" />Yes<form:radiobutton
                            path="validated" value="N" />No</td>
            </tr>
        </table>
        <input type="submit" class="button" value='<spring:message code="label.validateJob"/>' hidden="true" />
    </form:form>
</c:if>
<c:else>
    This job is validated
</c:else>

任何接受者？现在它不起作用。我认为我的语法是正确的，但我很新

Answer 1

<c:else>不存在，从未存在过。阅读您正在使用的内容the documentation，而不是尝试随机内容。

使用JSTL的正确方法是使用等于if / else的

<c:choose>
    <c:when test="condition">...</c:when>
    <c:otherwise>...</c:otherwise>
</c:choose>

Answer 2

等效代码是

    <c:choose>
    <c:when test="${validated != 'Y' }">
        <form:form id="newJob" method="post" action="updateValidated"
            commandName="jobModel">
            <form:input path="regattaId" type="hidden" />
            <form:input path="job_id" type="hidden" />
            <table>
                <tr>
                    <td><spring:message code="label.validated" />
                    <td><form:radiobutton path="validated" value="Y" />Yes<form:radiobutton
                            path="validated" value="N" />No</td>
                </tr>
            </table>
            <input type="submit" class="button"
                value='<spring:message code="label.validateJob"/>' hidden="true" />
        </form:form>
    </c:when>
    <c:otherwise>
        This job is validated
    </c:otherwise>
</c:choose>

Jstl的c：if标签没有伴随c：else标签。试试c：选择！

jstl if / else不能正常工作
