Getting selected values from a select statement

[Tripharn Teki]

Hi,

I have the following code in the HTML

<select size="1" name="newtitle" >
<% // Need to fill select with available campuses
while (titleit.hasNex t())
{
temp = (String)titleit .next();
// Check if it is the selected campus already
if (temp.equals(ti tle))
{
// Make it the selected campus by default
out.println("<o ption selected>"+temp +"</option>");
}
else
{
// Add it normally
out.println("<o ption>"+temp+"</option>");
}
}

Which just fills up a combo box. Now in the JSP on the submit page I have

String[] titleU = request.getPara meterNames("new title");

If I use following line I get an error...

out.println(tit leU[0]);

Whats the deal??

This shouldn't even compile. getParameterNam es()
returns an Enumeration, not an array.

If you mean getParameterVal ues(), did you remember
the </select>? You don't show it above.

Re: Getting selected values from a select statement

Yea ooops, it was getParameterVal ues()

But the problem was that in the select statements you need to add
value=blah... which I didn't have...
So essentially in the selectbox you can have someting like Hello World, but
the value can be different, or nothing if you completely miss it out.

Thanks anyway,
