Question

<jsp:element name="input">
    <jsp:attribute name="type">radio</jsp:attribute>
    <jsp:attribute name="id">${status.index}${loop.index}</jsp:attribute>
    <jsp:attribute name="name">skillLevel[${status.index}].skillLevelId</jsp:attribute>
    <jsp:attribute name="value">${4 - loop.index}</jsp:attribute>
    <c:if test = "${(4 - loop.index) == skillLevel.getSkillLevelId()}">
        <jsp:attribute name="checked">checked</jsp:attribute>
    </c:if>
</jsp:element>

显示错误c：如果标记不能在jsp：element标记内。我只想添加属性＆＃34; checked＆＃34;对于＆＃34;输入＆＃34;基于测试条件的元素。

Answer 1

你试过这样的吗？

<c:if test = "${(4 - loop.index) == skillLevel.getSkillLevelId()}">
<c:set var="isChecked" value="checked"/>
</c:if>

<jsp:element name="input">
    <jsp:attribute name="type">radio</jsp:attribute>
    <jsp:attribute name="id">${status.index}${loop.index}</jsp:attribute>
    <jsp:attribute name="name">skillLevel[${status.index}].skillLevelId</jsp:attribute>
    <jsp:attribute name="value">${4 - loop.index}</jsp:attribute>
    <jsp:attribute name="${isChecked}">${isChecked}</jsp:attribute>
</jsp:element>
