Your page:
<select name="lbItems" onChange="AJAXCall(this.value);">
<option value="1">1</option>
etc etc etc
</select>
Javascript function on your page
function AJAXCall(val)
{
//--- make your ajaxcall here
url = "mypage.php?id=" + val;
}
php page:
<?php
$id = 0;
if( isset($_GET['id]) ) $id = $_GET['id'];
if( !is_numeric($id) ) $id =0;
//--- read database
$sql = "SELECT * FROM yourtable WHERE pk=".$id;
//--- loop through recordset and populate listbox
echo "<option value='".$recPK."'>".$recText."</option>\n";
?>
