Click to expand...
You cannot get it into a Java String unless you submit the form. Are you willing to do that? I guess not. Instead, you can get the desired result using JavaScript alone. Have a look at the following:

Code: 
<head>

	<script language='JavaScript'>

		function populateVillageValues()

		{

			document.VillageFrm.village_code.value = document.VillageFrm.village_name.value = '';

			if(document.VillageFrm.narp_zone_id.value != '0')

			{

				document.VillageFrm.village_code.value = document.VillageFrm.narp_zone_id.value;

				document.VillageFrm.village_name.value = document.VillageFrm.narp_zone_id[document.VillageFrm.narp_zone_id.selectedIndex].text;

			}

		}

	</script>

</head>

<html>

<form name='VillageFrm' method='post'>

<table>

<tr>

	<td>

		<h4>[b]Narp Zone

	</td>

	<td>

		<select id='narp_zone_id' name='narp_zone_id'>

		<option value="0">(Select)</option>

		<option value="1">Central Dry Zone - Sirsa</option>

		<option value="2">Central Maharashtra Plateau Zone - Aurangabad</option>

		<option value="3">Central Namada Village Zone - PawarKhera</option>

		<option value="4">Central Plain Zone - Kanpur</option>

		<option value="5">Central Plain Zone - Ludhiana</option>

		<option value="6">Central Vidharba Zone - Yavatmal</option>

		</select>

	</td>

	<td align=left>&nbsp</td>

</tr>

<tr>

	<td align=left>[b]

	<h4>Village Code

	</td>

	<td align=left>

	<input type="text" name="village_code" size="25" maxlength="100">

	</td>

	<td align=left>&nbsp</td>

	<td>

	<input type="button" name="fetch" value="Fetch Village Code" onClick="populateVillageValues()"/>

	</td>

</tr>

<tr>

	<td align=left>[b]

	<h4>Village Name

	</td>

	<td align=left colspan='2'>

	<input type="text" name="village_name" size="55" maxlength="200">

	</td>

</tr>

</table>

</form>

</html>

Let me know if you still wish to have the "Java String" solution.
