getCity.php

<?php
include('conn.php');

$country = $_GET['city'];

$query ="select * from $database.FQ64006 WHERE SCYQ64CTYPE='" . $country . "'";
$tresult = odbc_exec($connection,$tquery);
?>
    <select name="city" id="last-name" class="city">
    <option value="">Select State</option>
<?php
    while($trow=odbc_fetch_array($tresult)) {
?>
    <option value="<?php echo trim($trow["SCYQ64TYPE"]); ?>"><?php echo trim($trow["SCYQ64TYPE"]); ?></option>
<?php } ?>
</select>

Don't quite understand what you are trying to do, but from what I see, the code for country works as the code:

$(document).ready(function()
        {
            $(".country").change(function()
            {
            var id=$(this).val();
            var dataString = 'id='+ id;
            $.ajax
            ({
            type: "POST",
            url: "ajax_city.php",
            data: dataString,
            cache: false,
            success: function(html)
            {
            $(".city").html(html);
            } 
            });
            });
        });

when country is changed, the data sent to ajax_city.php and after processed, the return is handled by success: function(html) where the html returned is being used to $(".city").html(html);

The second part is not taking effect as from code:

$.ajax({
        url:'getCity.php',
        type:'GET',
        data:{city:firstname},
        dataType:'json',
        cache:false,
        success:function(data){
        data=JSON.parse(data); //no need if dataType is set to json
         var ddl = document.getElementById('last-name');                      
         for(var c=0;c<obj.length;c++)
              {              
               var option = document.createElement('option');
               option.value = obj[c];
               option.text  = obj[c];                           
               ddl.appendChild(option);
              }
    },
        error:function(jxhr){
        alert(jxhr.responseText);
    }
    }); 

First of all, as the commented, there is no need to call data=JSON.parse(data); as your datatype already set to json format. And the function which handle the success the the returned as 'data' and from your code for(var c=0;c<obj.length;c++), you try to process with obj which it don't having any values. Therefore, the looping will not doing anything as obj.length is 0.

Sorry for the late.lps

thanks

It will display only the first dropdown box. i am not getting the values in the second dropdown.
