1.第一步获取前台DataGrid中的数据

var rows = $(\’#tb).datagrid(“getRows”);
            if (rows.length == 0) {
                $(“#ShowMsg”).html(“没有数据可供导出!”);
                return;
            }
            var columns = new Array();
            var fields = $(\’#tb).datagrid(\’getColumnFields\’);
            for (var i = 0; i < fields.length; i++) {
                var opts = $(\’#tb).datagrid(\’getColumnOption\’, fields[i]);
                var column = new Object();
                column.field = opts.field;
                column.title = opts.title;
                columns.push(column);
            }
            var excelWorkSheet = new Object();
            excelWorkSheet.rows = rows;
            excelWorkSheet.columns = columns;
            excelWorkSheet.sheetName = “名字”;
          

2.发布Post请求到后台

   $.post(“XXXX.aspx”, { IsAction: \’Method\’, ActType: \’exportXls\’,
                ExcelWorkSheet: JSON.stringify(excelWorkSheet) //将数据转化为Json字符串
            },
                function (data) {
                    成功后操作
                  }
            );

3.在后台将Json串转化为Datatable后写入到Excel模版中；
