Populating a value based on the option selected in the dropdown

[anita prat]

Hi,
I have a jsp here I have a drop down list that contains the list of franchises. There is nother field franchise code on the jsp which will have the value populated based on the valkue in the drop down. These two are properties of a form bean Franchise which is available in the form bean associated with the jsp.
FranchiseVO bean has properties franchisename and franchisecode. THe names appear in the dropdown. Based on the franchisename selected , the value of the franchise code should get populated. How do I acheive this? Do I need to use a hidden parameter to pass to the javascript?

<select id="franchiseVO.franchiseName" name="franchiseVO.franchiseName" >
<c:forEach var="franchiseVO" items="${addFranchiseForm.franchises}">                                    
 <option value="<c:out value="${franchiseVO.franchiseName}"/>"><c:out value="${franchiseVO.franchiseName}"/></option>                               
 </c:forEach>  
</select>

<h6>Participant Code</h6> have to populate the value here i.e the code of the franchisename selected in the above drop down.

That depends what you mean by "selected". Do you mean:

The value that will be set as selected by the JSP -- and therefore known at page-generation time.

The value that will be chosen by the end user after the page has been displayed in the browser.

Well, by that time the JSP has been evaluated on the server and is long gone. So you'll need to handle the change event for the dropdown on the client using JavaScript.
