<tr>
                        <th data-options="field:'HName',title:'节假日名称',width:100,halign: 'center',editor:'text'"></th>
                        <th data-options="field:'HBeginDate',title:'开始日期',width:100,halign: 'center',editor:'datebox'"></th>
                        <th data-options="field:'HEndDate',title:'截止日期',sortable:true,width:100,halign: 'center',editor:'datebox'"></th>
                        <th data-options="field:'IsState',title:'状态',align:'center',halign:'center',width:100,formatter:HolidayIsState"></th>
                    </tr>

$('#HolidayDg').iDatagrid('insertRow', {
                index: 0,
                row: {
                    HName: '',
                    HBeginDate: '',
                    HEndDate: ''
                }
            });
            $('#HolidayDg').iDatagrid("beginEdit", 0);//i为需要编辑的行号
            $('#HolidayDg').iDatagrid("selectRow", 0);//选中第一行
            $('#SaveOrRevoke').css('display', 'block');//显示保存按钮与撤销按钮
            $('.switchbutton').switchbutton({onText: '',offText: ''});//渲染行内的操作按钮

function SaveAjax() {
            try {
                var row = $('#HolidayDg').iDatagrid('getSelected');//获取新增行的数据
                alert(row.HName);
            } catch (e) {
                alert(e);
            }
        }
