jsp : set an attribute of an element based on condition

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>

Shows error that c:if tag cant be within jsp:element tag. I just want to add the attribute "checked" for the "input" element based on the test condition.

Answer 1

Have you tried like this ?

<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>
