                        if (!empty($employees)) {
                            foreach ($employees as $emp) {
                                 ?>

                                <tr>

                                    </td>

                                    <td class='text-center'>
                                     <button type="submit"  onClick="return ConfirmDelete()" class="btn btn-danger btn-xs confirmation empdelete" id="<?php echo $emp->id;?>"><i class='fas fa-times'></i></button>
                                     </td>
                               </tr>

                                <?php
                            }
                        }
                        ?>
                    </tbody>
    <script>
$(document).ready(function(){
$(".empdelete").click(function(e){
    alert();
   e.preventDefault(); 
    $.ajax({
      alert();
      type: "POST",
      url: "<?=site_url('Employee/delete');?>",
      cache: false,
      data: {id:$(this).attr("id")}, // since, you need to delete post of particular id
      success: function(data) {
         if (data){
            alert("Success");
         } else {
             alert("ERROR");
         }
         return false;

       }
   });
});
});
</script>

Here is the my controller:

  function delete()  
  {
    $id = $this->input->post('id'); // get the post data
    $empdelete=$this->Emp_model->delete($id);
    if($empdelete){
        echo true;
    } else {
        echo false;
    }
 }

Here is my model's method delete:

function delete($id)
{ 
$sql  = "DELETE FROM employees WHERE id=?";
return $this->db->query($sql,array($id));

}

Can any one help me how can i do that with out page refresh i want to delete my record.

Thanks in advance.

Try this:

$(document).ready(function () {
        function ConfirmDelete() {
            var x = confirm("Are you sure you want to delete?");
            if (x)
                return true;
            else
                return false;
        }
        $(".empdelete").click(function (e) {
            var obj = $(this);
            e.preventDefault();
            //alert(); what's this do?
            if (ConfirmDelete() == false) {
                return false;
            }
            $.ajax({
                //alert(); this can't go here
                type: "POST",
                url: "<?php echo site_url('Employee/delete'); ?>",
                cache: false,
                data: {id: $(this).attr("id")},
                success: function (data) {
                    console.log('ajax returned: ');
                    console.log(data);
                    if (data) {
                        obj.closest('tr').remove();
                        alert("Success");
                    } else {
                        alert("ERROR");
                    }
                    return false;
                }
            });
        });
    });

and remove HTML onClick:

<button type="submit" class="btn btn-danger btn-xs confirmation empdelete" id="<?php echo $emp->id;?>"><i class='fas fa-times'></i></button>
