ajax会返回，但是不刷新当前页面。要强制刷新才管用

	require_once("config.php");
	header('content-type:application/json');
	$oid=$_POST['oid'];
	$sql="delete from `djs_shops_orders` where oid = '$oid'";
	$result = mysql_query($sql);
	$row = mysql_fetch_row($result);

success: function()
        {                              
            alert("成功取消订单！");      
            window.reload();       
        }

success: function()
        {                              
            alert("成功取消订单！");      
                $(obj).closest('tr').remove();
        }
