JS部分

			var orderNosList = new Array();
			var rows = $("#dg_linkOrder").datagrid("getChecked");
			if(rows.length < 1){
				$('#error').dialog('open').dialog('center').dialog('setTitle', '错误提示');
				$('#error').text("请选择一条数据");
			}else  {
				for (var i = 0; i < rows.length; i++) {
					orderNosList[i] = rows[i].orderNo;
				}

				var params = {
						reserveOrderNoList:orderNosList
					 };

				$.ajax({
					url : api.LINK_ORDER_RESERVE_RETRY,
					data : JSON.stringify(params),
					type : 'POST',
					contentType: "application/json",
					dataType : 'json',
					success : function(res) {
						var str = '';
						$(res.reserveFlowList).each(function(i, obj){
							var responseCode = obj.responseCode;
							var orderNo = obj.reserveFlow.orderNo;
							if (responseCode == 0) {
								str += "订单号为"+ orderNo +"成功<br/>";
							} else {
								str += "订单号为"+ orderNo + obj.responseMsg +"<br/>"
							}
						});

						$('#error2').dialog('open').dialog('center').dialog('setTitle', '提示');
						$('#error2').html(str);
						// 刷新列表
						linkOrder.unfresh_LinkOrder();
					}
