    var idsInOrder = $("#sortable").sortable("toArray");
    console.log(idsInOrder);
    var string_arr = idsInOrder.toString();
    console.log("STRN-" + string_arr);

            {
                id = id + s + ",";
            }
            //int id = ids[i];
            //int ordinal = i;
            //...
        }
        return id;
    }

推荐答案

（ ＃sortable）。sortable（ toArray）;
console .log（idsInOrder）;
var string_arr = idsInOrder.toString（）;
console .log（ STRN- + string_arr）;
var url = pgArrange.aspx / SaveListOrder;

("#sortable").sortable("toArray"); console.log(idsInOrder); var string_arr = idsInOrder.toString(); console.log("STRN-" + string_arr); var url = "pgArrange.aspx/SaveListOrder";

.ajax（{
type： POST，
url：url，
contentType： application / json; charset = utf-8，
dataType： json，
数据： {'catalogname'：' + string_arr + '}，
成功： function （数据）{
}
}）;
}

.ajax({ type: "POST", url: url, contentType: "application/json; charset=utf-8", dataType: "json", data: "{'catalogname':'" + string_arr + "'}", success: function (data) { } }); }

[WebMethod]
    public static string SaveListOrder(string ids)
    {
        string id = "";
        foreach(string s in ids.Split(','))
        {
            if (s != "")
            {
                id = id + s + ",";
            }
            //int id = ids[i];
            //int ordinal = i;
            //...
        }
        return id;
    }

使用Fiddler检查浏览器和服务器之间的流量，因为它经常会显示真实的错误消息。在我的头顶，你传递了一个名为catalogname的参数，但你的方法是期待一个名为ids的参数。参数名称必须匹配。

Use Fiddler to examine the traffic between your browser and server as it often shows you the real error messages. Off the top of my head you are passing a param called catalogname but your method is expecting a param called "ids". The param names have to match.
