Question

I’m trying and searching now for days and can’t find an answer.
My problem is this: I use a Hyperlink and Javascript to submit a form, but I also need to submit a parameter with the link. The code looks like this:

<form action="Action.jsp" method="post" id="form-id">
  <input .../>
  ...
  <c:forEach items="${items}" var="item" varStatus="vs">
    <a href="Action.jsp?id=${vs.count}" 
       onclick="javascript:document.forms['form-id'].submit(); return false">
       ${vs.count}
    </a>
  </c:forEach>
</form>

If I leave away the return false the param id is transferred but the other <input .../> parameters not and vice versa. How you see I can’t use a <input type="hidden" .../> param, because I need only the param of the link.

If you please could help me, I would be grateful….

If you add a hidden input outside the loop, you can set the value of that input before submitting:

<form action="Action.jsp" methode="post" id="form-id">
  <input .../>
  <input type="hidden" id="button-id"/>
  ...
  <c:forEach items="${items}" var="item" varStatus="vs">
    <a href="Action.jsp" 
       onclick="javascript:document.getElementById('button-id').value=${vs.count};document.forms['form-id'].submit(); return false">
       ${vs.count}
    </a>
  </c:forEach>
</form>
