将Jquery值分配给ASP文本框

Question

我正在尝试将JQuery变量分配给gridview内的ASP.NET文本框。这是我的ASP代码-

<label id="test" runat="server"></label>
<asp:HiddenField ID="hdnexclname" runat="server" />
<div class="container">
            <div class="modal fade" id="detailModal">
                <div class="modal-dialog">
                    <!-- Modal content-->
                    <div class="modal-content">
                        <div class="modal-header">
                            <h4 class="modal-title">Edit Record</h4>
                        </div>
                        <div class="modal-body">
                            <asp:UpdatePanel ID="updatepanel" runat="server">

 $(function () {
                    var data = [];
                    $("#btnedit").click(function () {

                        $("#gvCost input[type=checkbox]:checked").each(function (i) {

                            var row1 = $(this).closest("td").next("td")[0];
                            var row2 = $(this).closest("td").next("td").next("td")[0];
                            var row3 = $(this).closest("td").next("td").next("td").next("td")[0];

                            var $test = $("#div1").find(".abc").val();

                            $('#<%=hdnexclname.ClientID %>').val(row1);
                            $('#test').val(row1);

                            alert($('#test').val(row1));

                            alert($('#<%=hdnexclname.ClientID %>').val(row1));

                            if (typeof row1 === "undefined") {
                                row1 = "";
                            } else {



                            }

                            if (typeof row2 === "undefined") {
                                row2 = "";
                            } else {

                            }

                            if (typeof row3 === "undefined") {
                                row3 = "";
                            } else {

                            }

                            console.log(row2);
                            console.log(row3);

                        });
                        $('#detailModal').modal('show');
                        return false;
                    });
                });

我总是会警惕“未定义” 或“ [对象对象]” 。也许我在犯一些愚蠢的错误，但无法弄清楚。需要一些帮助来解决此问题。 这是我已经尝试过的-

var $txt = $item[0];

var $test = $($txt).val('text...');

var $test = $('#<%=gvCosttoServeEditMultiple.ClientID %>').find('input:text[id$="txtFY"]').val('Your value.');

var $arrT = $('#<%=gvCosttoServeEditMultiple.ClientID %>').find('input:text[id$="txtFY"]');

var $test = $("#gvCosttoServeEditMultiple").find(".abc").val();

var $country = $(this).find('input:text[id="txtfy"]').val();
