option value structure

[keydrive]

I am looking for alternatives on storing menu option lists rather than the current process method. On a jsp form, there must be a cleaner way to store the user selection outside of the below and not using cookies.

Suggestions and comments are welcome... tks

 -- html
<%
    String  countOptions= request.getParameter("countOptions");
        if(countOptions == null)
        {
            countOptions = "30";
        }    
%>
 
Count Options
 
<%  if(countOptions.equals("10")) { %> 
         <select name="countOptions">
    <option value="10" selected="yes"> 10 </option>
    <option value="20"> 20 </option>
    <option value="30"> 30 </option>
         </select>
<% }
       if(countOptions.equals("20")) { %> 
        <select name="countOptions">
    <option value="10"> 10 </option>
    <option value="20" selected="yes"> 20 </option>
    <option value="30"> 30 </option>
         </select>
<% }
        if(countOptions.equals("30")) { %> 
          <select name="countOptions">
    <option value="10"> 10 </option>
    <option value="20"> 20 </option>
    <option value="30" selected="yes"> 30 </option>
         </select>
<% }
 
---------------- form 2 --------------
<%
<input type="hidden" name="countOptions"  value="<%=countOptions %>">
%>

What do you mean by storing? How are you planning to use these values - across a number of pages?

There's a bit of redundancy in your code. You only need the select element once and use the JSP within each option tag unless you don't like to mix server-side and HTML too much.

You’re on the right trail. The redundancy is actually what I want to remove.
Right now I code "selected" for each individual menu option. On submit, the page is rendered with new information but still contains the menu options. If each menu option is not coded like the above the user selection is lost and a default is used.

You could try something like:

<select name="countOptions">
    <option value="10" <%  if(countOptions.equals("10")) { %>selected="yes"<% }%>> 10 </option>
    <option value="20" <%  if(countOptions.equals("20")) { %>selected="yes"<% }%>> 20 </option>
    <option value="30" <%  if(countOptions.equals("30")) { %>selected="yes"<% }%>> 30 </option>
</select>

Genius!

Works perfectly and very clean.
Hundreds of lines of code have been cleaned up.

Big Thanks.
