Question

因为我的生活无法弄清楚如何从我的控制器中显示我从'cics'对象返回的值。当我调试控制器时，它返回值。但我似乎无法在ajax调用中弄清楚我的'Success'方法。有人可以帮我解决我出错的地方吗？此外，这可以有多个产品，所以我试图保持它特定于该元素。任何帮助将不胜感激。

 function FillProductbyupc(el) {
        var val = el.value;
        var container = $(el).parent().parent();
        var pcics = container.children(".cics");
        var elements = document.getElementsByClassName('product');


        $.ajax({
            url: '/Case/GetData/',
            type: "GET",
            dataType: "JSON",
            data: "upc=" + val,
            success: function (cics) {
                //container.cics.val(cics.CorpItemCode);

                $("#upc").html(""); // clear before appending new list
                $("#corpitemcode").html(""); // clear before appending new list
                $("#itemdesc").html(""); // clear before appending new list
                $("#corpitemcode").append(
                    $('#corpitemcode').val(cics.CorpItemCode));

                $("#itemdesc").append(
                    $('#itemdesc').val(cics.ItemDsc));

            },
            error: function () {
                alert("UPC does not exist");
            }
        });
    }

这是我的产品。

控制器。

  public JsonResult GetData(string upc, decimal? corpitemcode)
    {
        if (!string.IsNullOrEmpty(upc))
        {
            upc = upc.Replace("-", "");
        }

        CICS cics = new CICS();
        cics = CICSManager.GetbyUPCorCorp(upc, corpitemcode);

        return Json(cics, JsonRequestBehavior.AllowGet);
    }

工作职能

function FillProductbyupc(el) {
var val = el.value;
var container = $(el).parent().parent();
var pcics = $(container).find('.prodcic');
var pdesc = $(container).find('.itemdsc');

$.ajax({
    url: '/Case/GetData/',
    type: "GET",
    dataType: "JSON",
    data: "upc=" + val,
    success: function (cics) {
        pcics.val(cics.CorpItemCode);
        pdesc.val(cics.ItemDsc);


    },

    error: function () {
        alert("UPC does not exist");
    }
});

}

html()和.append()用于添加到HTML节点。我怀疑你想要的是：

        success: function (cics) {
            //container.cics.val(cics.CorpItemCode);

            $("#upc").val("");
            $("#corpitemcode").val(cics.CorpItemCode);
            $("#itemdesc").val(cics.ItemDsc);
        },

在插入新HTML之前无需清除。
