hey guys i am facing trouble in calling controller method from javascript pls help . .

my view is

<script type="text/javascript">
    function kccbranchselect()
    {
        $.ajax({
        type : 'POST',
        data : 'addreceiptkccbranchid='+ $('#addreceiptkccbranch').val(),
        url : '<?php echo base_url();?>index.php/ctl_dbcont/getmembersbybranch',
        success :   function(data){
                        $('#addreceiptddsmember').val(data);
                    }
        });
    }
</script>
<select id="addreceiptkccbranch" name="addreceiptkccbranch" onChange="kccbranchselect();" tabindex="1" >
    <option value="">--SELECT--</option>
    <?php foreach($branchlist as $value):?>
        <option value="<?=$value['branch_id']?>"><?=$value['branch_name']?></option>
    <?php endforeach; ?>
</select>
<select id="addreceiptddsmember" name="addreceiptddsmember" tabindex="1">
    <?php foreach($member_by_branch as $row) { ?>
        <option value = ""></option>
    <?php } ?>
</select>

my controller is

function getmembersbybranch()
{
    $this->load->model('mod_user');
    $addreceiptkccbranchid      =   $_POST['addreceiptkccbranchid'];
    $data['member_by_branch']   =   $this->mod_user->member_receipt_dds($addreceiptkccbranchid);
    redirect('view_addreceipts');
}

i am generating a dropdown by selecting another dropdown option . . i cant access the controller method by putting url : '<?php echo base_url();?>index.php/ctl_dbcont/getmembersbybranch', in ajax ,why ??

The redirect statement here is invalid, as it is an AJAX request. You have to send html or json response from server, which you can process at client side. e.g.

$data['member_by_branch']=$this->mod_user->member_receipt_dds($addreceiptkccbranchid);
echo $data['member_by_branch']; //assuming its html

so on client side, you just have to use this statment in you callback method.

$('#addreceiptddsmember').html(data);
