Question

I wanted to use Spring MVC hidden tag in below code. Is this possible in below code, what I have to write in my controller to do that or what I am doing is correct.

    <c:forEach var="record" items="${records}">
        <tr>
            <td>
                <form:form id="myForm" action="list.html" method="post">
                    <input type="hidden" name="record" value="${record}" />
                    <a href="#" onclick="document.getElementById('myForm').submit();">Submit</a> 
                </form:form>
            </td>
        </tr>
     </c:forEach>

Any help will be highly appriciated.

Answer 1

You are on the right track [depending on what your backing bean is], but in order to bind an ID as a hidden field on submission automatically to a “Person” bean (in this example), you would do something like:

<c:forEach var="person" items="${persons}" varStatus="status">
    <tr>
        <c:set var="personFormId" value="person${status.index}"/>
        ....
        <form id="${personFormId}" action="${deleteUrl}" method="POST">
            <input id="id" name="id" type="hidden" value="${person.id}"/>
        </form>

        <td>${person.firstName}</td>
        <td>${person.lastName}</td>
        .... 
    </tr>
</c:forEach>

In case you’d like to render a hidden field, you would use a form:hidden tag:

<form:hidden path="id" />

Take a look at Hidden Input Tag section of the Spring docs.
