'Date To' 应该是 'Date From' 模态弹出 jqgrid 的开头

Question

嗨，我在 MVC 中使用 Jqgrid，要求就是这样。在 jqgrid 的模型弹出窗口中添加/编辑一行。我有 4 列。
DateFrom、DateTo、类型、备注
我正在使用 jquery datepicker..
我的要求
添加第一行后.. 在添加第二行.. DateFrom 字段（第二行）应该是之前添加行的 DateTo 字段的下一个日期.

这是我的网格

    initDateEdit = function (elem) {
                setTimeout(function () {
                    $(elem).datepicker({
                        dateFormat: "m-d-yy",
                        showOn: "button",
                        changeYear: true,
                        changeMonth: true,
                        showButtonPanel: true,
                        showWeek: true
                    });
                }, 50);
    },
    initDateSearch = function (elem) {
                setTimeout(function () {
                    $(elem).datepicker({
                        dateFormat: "m-d-yy ",
                        changeYear: true,
                        changeMonth: true,
                        showButtonPanel: true,
                        showWeek: true
                    });
                }, 50);
    },

    jQuery("#dateGrid").jqGrid({
            height: 100,
            width: 1000,
            colNames: ['DateFrom', 'DateTo', 'Type', 'Remarks'],
            colModel: [

                {
                    name: 'DateFrom', index: 'DateFrom', width: 60, editable: true, sorttype: "date",
                    formatter: 'date',
                    formatoptions: {
                        srcformat: 'm/d/Y',

                    },
                    editoptions: { dataInit: initDateEdit, size: 14 },

                },
                {
                    name: 'DateTo', index: 'DateTo', width: 80, editable: true, sorttype: "date",
                    formatter: 'date',
                    formatoptions: {
                        srcformat: 'm/d/Y',

                    },
                    editoptions: {
                        dataInit: initDateEdit, size: 14,

                    },

                },
                {
                    name: 'Type', width: 80, editable: true, formatter: "select",
                    edittype: "select", editoptions: { value: "Open:Open;Maintainance:Maintainance;Closed:Closed", defaultValue: "Open" },
                },
                 {
                     name: 'Remarks', index: 'Remarks', width: 80, editable: true
                 }
                ,
            ],
            // multiselect:true,
            pager: "#datePager",
            loadonce: true,
            sortname: 'Client',
            ignoreCase: true,
            sortorder: 'asc',
            gridview: true,
            autoencode: true,
            rowNum: 10,
            rowList: [5, 10, 20, 50],
            caption: "Add Durations",
            viewrecords: true,
            editurl: "clientArray",
            onSelectRow: function (id) {
                var selRows = $(this).jqGrid('getGridParam', 'selarrrow');
                if (selRows.length > 1) {
                    btnEdit.disabled = true;
                    btnDel.disabled = true;
                }

                else if (selRows.length == 1) {
                    btnEdit.disabled = false;
                    btnDel.disabled = false;
                }
            },




    }).jqGrid("navGrid", "#datePager", { search: true, edit: false, add: false, del: false, searchtext: "Search" }, {}, {}, {
            multipleSearch: true,
            overlay: false,
            onClose: function () {

                $("div#ui-datepicker-div.ui-datepicker").hide();
            }
    }).jqGrid("filterToolbar", { defaultSearch: "cn" });
});

所以现在我需要访问网格中第一行的 DateTo 值。并且在 DateFrom 的默认值中编写一个函数来将 1 加到从获取的日期DateTo 并将其显示在 DateFrom 有人可以给我任何演示/帮助，以了解如何使此功能正常工作吗？ 谢谢！

这是我最终找到的解决方案。

jQuery("#GridId").jqGrid({

        height: 100,
        width: 1000,
        colNames: ['Date From', 'Date To', 'Type', 'Remarks'],
        colModel: [
            {
                name: 'DateFrom', index: 'DateFrom', width: 60, editable: true, sorttype: "date",
                formatter: 'date',
                formatoptions: {
                    srcformat: 'm/d/Y',

                },
                editoptions: { dataInit: initDateEdit, size: 14 ,
                    defaultValue: function () {




                        var ids = $("#GridId").jqGrid('getDataIDs');
                        if (ids.length >= 1) {
                            //get first id
                            var cl = ids[0];
                            //fetch row data 
                            var rowData = $("#GridId").getRowData(cl);
                            //fetch individual cell value
                            var celValue = $("#GridId").jqGrid('getCell', cl, 'DateTo');

                            var currentTime = new Date(celValue);

                            var month = parseInt(currentTime.getMonth() + 1);
                            month = month <= 9 ? "0" + month : month;

                            var day = currentTime.getDate();
                            day = day <= 9 ? "0" + day : day;

                            var year = currentTime.getFullYear();
                           var  months= [31,28,31,30,31,30,31,31,30,31,30,31];

                           var ndays = months[month - 1];
                            if (month == 02)
                            {

                                        ndays=29;
                            }
                            day = day + 1;

                            if(day>ndays)
                            {
