                            var my_value = ($(this).val());
                            alert(my_value);
                            var toLoad = "ajax.php/"+my_value;
                            $("#my_div").load(toLoad,function(response,status,xhr){
                                if(status == "error"){
                                    alert("Please check again have some error ");
                                }
                                else{
                                    alert($(this).val());

                                }
                            });
                            return false;
                        }
                    });
