#2220 — Passing value from Struts

  To: comp.lang.java.gui,comp.l
Hi,

 I am populating JSP page with rows retrieved from the database and 
represented as a List of Beans in forEach loop:
<c:forEach var="list" items="${OperationsForm.OperationsList}">
          ...
  <c:choose>
            <c:when test="${list.isCompleted =='Y'}" >
                <td width="100">Completed</td>
                <td width="100">&nbsp;</td>
            </c:when>
            <c:otherwise>
                <td width="100">Pending</td>
                    <td width="100"><input type="image" onclick=" 
rowId=value; form.action='action.do?command=notify'" 
value="${list.OperationId}" />
                    </td>
            </c:otherwise>
            </c:choose>
            </tr>
        </c:forEach>
Have hidden field:  html:hidden property="rowId" value="-1"/>

User is clicking the button corresponding to one of the rows
and I need to pass the  value of that  rowId to the Action class, so it does 
something in the database [action completed]
Now how do I pass it , is that the right way of doing it  with calling
request.getSession().getAttribute(rowId) in the Action class ?
As of now I am getting Javascript error "Object doesn't support this 
property or method", complaining about rowId=value;

Using Struts 1.3

Please help !

TIA,
Oleg.

You don't need JavaScript. Use the Struts <html:button> tag:

<html:form action="myActionInStrutsConfig">

     ...

     <c:forEach var="item" items="${OperationsForm.OperationsList}">

         <html:button property="x" value="${item.OperationId}" />

     </c:forEach>

</html:form>

When the button is pressed, the form is submitted and you get a request 
parameter "x" available to your Action set to the operation id value 
that's on the button. Obviously you'll have a better name for "x".
