Problem in SELECT TAG using variables

Question

Hi all,
I have a JSP page which updates the record for a user.Now there is a HTML select tag and when the user queries its data this SELECT tag will automaticaly select the user stored item in database automatically. It means the select tag will have a variable to select the options. Now how can i use variables in SELECT TAG. Please help needed.

Answer 1

I'm not exactly sure what you are asking, but here goes.
First, are you able to populate the select box with all the names... this is what it sounds like to me.
Or are you not able to populate it nor select it.
I use JSTL for all my jsps... so for me I would store a collection on the form and then iterate through it. (arrayList being my preference)
look into using <c:forEach> or you could try <logic:iterate> which I've used before but it has been several years.
here is an example block of code.
Sorry this is going to be a bit convoluted because of what I'm doing with it..
but I have an ArrayList that contains string arrays... position 0 being the value I want returned (like 1 through 10) and position 1 being the text representation..
so it comes out like
1 - Option 1
2 - Option 2
You will notice the if statement where I check to see if the localList[0] is equal to the view field. view would be your selected value.
<SELECT name="view" size="7"
     multiple="multiple" class='OmniDlgLabel'>     
               <c:if test="${sessionScope.PHI2Form.localList!=null}">
                    <c:forEach var="localList"
                         items="${sessionScope.PHI2Form.localList}" varStatus="status">
                         <OPTION value='<c:out value="${localList[0]}"/>'
                                   <c:if test="${sessionScope.PHI2Form.view==localList[0]}">SELECTED</c:if>>
                         <c:out value="${localList[0]}"/>-<c:out value="${localList[1]}" /></OPTION>
                    </c:forEach>
               </c:if>          
</SELECT></TD>There is an extra > that I cannot get rid of.. should be there after the
<OPTION value='<c:out value="${localList[0]}"/>'
