hello,

I have a problem with dropdown list refreshing.
The code is pasted below:

<HTML>
<body >

<%@ page import="java.sql.* " %>
<%@ page import="java.util.*" %>

<jsp:useBean id="Lib" class="Lib.cddatabase">

</jsp:useBean>
<script language="javascript">

function locfun()
{
cdform.location.value = cdform.combo2.value;
}

function new1_click()
{
cdform.source.value = " ";
}

function new2_click()
{
cdform.location.value = " ";
}

function new3_click()
{
cdform.status.value = " ";
}

function new4_click()
{
cdform.vendorid.value = " ";
}

function statfun()
{
cdform.status.value = cdform.combo3.value;
}

function venfun()
{
cdform.vendorid.value = cdform.combo4.value;
}

function sourcefun()
{
cdform.source.value = cdform.combo1.value;
}

</script>

The problem is that as I change the value of dropdown list , combo1 the changes get reflected to the text box source .. but since the page is getting reloaded, the combo box gets refreshed and I lose the selected value..

I have a bean which gets the value from the database and returns an array.

I need the combo box to retain its previous value..
