eayUI-datagrid 的当前页合计and总合计
一、HTML代码
1 <table id="dg" class="easyui-datagrid" style="width: 100%; height: 400px;" data-options=""> 2 <thead> 3 <tr> 4 <th data-options="field:‘DeviceId‘,checkbox:true"></th> 5 <th data-options="field:‘DeviceName‘, width:120,align:‘center‘" >名称</th> 6 <th data-options="field:‘DeviceUnitName‘, width:80,align:‘center‘">单位</th> 7 <th data-options="field:‘MakePlace‘, width:120,align:‘center‘">产地</th>
<th data-options="field:‘OriginalValue‘,width:90,align:‘center‘">资产原值</th> 8 <th data-options="field:‘BuyTime‘, width:120,align:‘center‘">购置日期</th> 9 10 </tr> 11 </thead> 12 </table>
二、JS代码：showFooter: true,代表grid添加总合计行。
1 $(".easyui-datagrid").datagrid({ 2 rownumbers: true, 3 singleSelect: false, 4 fitColumns: false, 5 idField: ‘DeviceId‘, 6 method: ‘post‘, 7 url: ‘/Admin/Report/DeviceDetialListSearch‘, 8 remoteSort: false, 9 multiSort: false, 10 showFooter: true, 11 pagination: true, 12 pageSize: 10, 13 pageList: [10,20,30], 14 queryParams: { 15 ‘DeviceIdList‘:"", 16 ‘DeviceName‘:$("#DeviceName").combobox(‘getValue‘), 17 18 }, 19 onl oadSuccess: function () { 20 //$("#dg").datagrid(‘clearChecked‘);//清除复选框 21 //$("#dg").datagrid(‘load‘); 22 } 23 });
三、后台Controller函数 DeviceDetialListSearch(); StringBuilder jsonBuilder 就是要添加的Footer。和分页一起整合成Json传到前台datagrid，会自动识别。PageCount 是当前页行数，PageValues就是当前页 原值那一列 OriginalValue的总合计。SearchForDetail()求得是当前页的数据。SearchForDetailSum()求得是总合计。
1 public ActionResult DeviceDetialListSearch() 2 { 3 DataTable dt = new DataTable(); 4 FADeviceInfoModel InfoModel = new FADeviceInfoModel(); 5 string DeviceIdList = Request["DeviceIdList"]; 6 7 int pageSize = int.Parse(Request["rows"]); 8 int nowPage = int.Parse(Request["page"]); 9 int recordCount = 0; //搜索条件下的总记录数量 10 dt = InfoModel.SearchForDetail(pageSize, nowPage, out recordCount, DeviceIdList,Request["DeviceName"]); 11 //当前页统计 12 string PageValues = ""; 13 int PageCount = 0; 14 if (dt != null) 15 { 16 PageValues = dt.Compute("Sum(OriginalValue)", "").ToString(); 17 PageCount = dt.Rows.Count; 18 } 19 20 DataTable DtTotal = InfoModel.SearchForDetailSum(DeviceIdList,Request["DeviceName"]); 21 22 StringBuilder jsonBuilder = new StringBuilder(); 23 # region 当前页总合计 24 jsonBuilder.Append("{"); 25 jsonBuilder.Append("\""); 26 jsonBuilder.Append("DeviceName"); 27 jsonBuilder.Append("\":\""); 28 jsonBuilder.Append("当前页总合计"); 29 jsonBuilder.Append("\","); 30 37 jsonBuilder.Append("\""); 38 jsonBuilder.Append("DeviceUnitName"); 39 jsonBuilder.Append("\":\""); 40 jsonBuilder.Append("数量"); 41 jsonBuilder.Append("\","); 42 43 jsonBuilder.Append("\""); 44 jsonBuilder.Append("MakePlace"); 45 jsonBuilder.Append("\":\""); 46 jsonBuilder.Append(PageCount); 47 jsonBuilder.Append("\","); 48 49 jsonBuilder.Append("\""); 50 jsonBuilder.Append("OriginalValue"); 51 jsonBuilder.Append("\":\""); 52 jsonBuilder.Append("原值"); 53 jsonBuilder.Append("\","); 54 55 jsonBuilder.Append("\""); 56 jsonBuilder.Append("BuyTime"); 57 jsonBuilder.Append("\":\""); 58 jsonBuilder.Append(PageValues); 59 jsonBuilder.Append("\""); 60 jsonBuilder.Append("},"); 61 #endregion 62 63 #region 总合计 64 jsonBuilder.Append("{"); 65 jsonBuilder.Append("\""); 66 jsonBuilder.Append("DeviceName"); 67 jsonBuilder.Append("\":\""); 68 jsonBuilder.Append("总合计"); 69 jsonBuilder.Append("\","); 70 77 jsonBuilder.Append("\""); 78 jsonBuilder.Append("DeviceUnitName"); 79 jsonBuilder.Append("\":\""); 80 jsonBuilder.Append("数量"); 81 jsonBuilder.Append("\","); 82 83 jsonBuilder.Append("\""); 84 jsonBuilder.Append("MackePlace"); 85 jsonBuilder.Append("\":\""); 86 jsonBuilder.Append(DtTotal.Rows[0]["SumCount"]); 87 jsonBuilder.Append("\","); 88 89 jsonBuilder.Append("\""); 90 jsonBuilder.Append("OriginalValue"); 91 jsonBuilder.Append("\":\""); 92 jsonBuilder.Append("原值"); 93 jsonBuilder.Append("\","); 94 95 jsonBuilder.Append("\""); 96 jsonBuilder.Append("BuyTime"); 97 jsonBuilder.Append("\":\""); 98 jsonBuilder.Append(DtTotal.Rows[0]["SumOriginalValue"]); 99 jsonBuilder.Append("\""); 100 jsonBuilder.Append("}"); 101 #endregion 102 103 return Content(MyJson.DataTableToJsonByPage(dt, recordCount, jsonBuilder.ToString())); 104 }
四、Model函数：SearchForDetail()求得是当前页的数据。
1 public DataTable SearchForDetail(int pageSize, int nowPage, out int recordCount, string DeviceIdList, string DeviceName) 3 { 4 string sqlCondition = " "; 5 if (DeviceIdList != null && !DeviceIdList.Equals("")) 6 sqlCondition += " and FADeviceInfo.DeviceId not in (" + DeviceIdList + ")"; 7 if (DeviceName != null && !DeviceName.Equals("")) 8 sqlCondition += " and (FADeviceInfo.DeviceName like ‘%" + DeviceName + "%‘ or FADeviceInfo.DeviceInputCode like ‘%" + DeviceName + "%‘)"; 9 10 string sqlOn = " left join FADepartment on FADeviceInfo.DepartmentId=FADepartment.DepartmentId "; 11 sqlOn += " left join FADeviceUnit on FADeviceInfo.DeviceUnitId=FADeviceUnit.DeviceUnitId "; 12 13 string sqlOrder = " order by DeviceId desc "; 14 string sqlResult = " DeviceId,DeviceStatus,DeviceCode,DeviceName,DepartmentName,DeviceSpec,DeviceUnitName,OriginalValue,MakePlace,BuyTime,FinancialCode "; 15 16 string sqlSon = "(select top " + (nowPage - 1) * pageSize + " DeviceId from FADeviceInfo " + sqlOn + " where 1 = 1 " + sqlCondition + sqlOrder + ")"; 17 string sql = " select top " + pageSize + sqlResult + " from FADeviceInfo " + sqlOn + " where DeviceId not in " + sqlSon + sqlCondition + sqlOrder; 18 string sqlCount = "select count(*) from FADeviceInfo " + sqlOn + " where 1 = 1 " + sqlCondition; 19 20 DataTable dataTable = new DataTable(); 21 dataTable = db.MyExecuteQuery(sql); 22 recordCount =db.GetCount(sqlCount); 23 return dataTable; 24 }
SearchForDetailSum()求得是总合计。
public DataTable SearchForDetailSum(string DeviceIdListe, string DeviceName) { string sqlCondition = " 1=1 "; if (DeviceIdList != null && !DeviceIdList.Equals("")) sqlCondition += " and FADeviceInfo.DeviceId not in (" + DeviceIdList + ")"; if (DeviceName != null && !DeviceName.Equals("")) sqlCondition += " and (FADeviceInfo.DeviceName like ‘%" + DeviceName + "%‘ or FADeviceInfo.DeviceInputCode like ‘%" + DeviceName + "%‘)"; string sql = " select sum(OriginalValue) as SumOriginalValue,count(*) as SumCount from FADeviceInfo " + " left join FADepartment on FADeviceInfo.DepartmentId=FADepartment.DepartmentId " + " left join FADeviceUnit on FADeviceInfo.DeviceUnitId=FADeviceUnit.DeviceUnitId " + " where " + sqlCondition; DataTable dataTable = new DataTable(); dataTable = db.MyExecuteQuery(sql); return dataTable; }
五、table转Json函数：参数Footer 就是在 Controller ：DeviceDetialListSearch()函数里拼接的stringBuilder，总合计和当前页合计要怎么写怎么统计，可以自己去拼接，然后传到转换函数里来。
1 public static string DataTableToJsonByPage(DataTable dt, int total, string footer) 2 { 3 StringBuilder jsonBuilder = new StringBuilder(); 4 //添加表格总行数 5 jsonBuilder.Append("{\"total\":" + total + ",\"rows\":"); 6 //添加行数据 7 jsonBuilder.Append("["); 8 for (int i = 0; i < dt.Rows.Count; i++) 9 { 10 jsonBuilder.Append("{"); 11 for (int j = 0; j < dt.Columns.Count; j++) 12 { 13 jsonBuilder.Append("\""); 14 jsonBuilder.Append(dt.Columns[j].ColumnName); 15 jsonBuilder.Append("\":\""); 16 jsonBuilder.Append(dt.Rows[i][j].ToString()); 17 jsonBuilder.Append("\","); 18 } 19 jsonBuilder.Remove(jsonBuilder.Length - 1, 1); 20 jsonBuilder.Append("},"); 21 } 22 if (dt.Rows.Count != 0) 23 { 24 jsonBuilder.Remove(jsonBuilder.Length - 1, 1); 25 } 26 jsonBuilder.Append("]"); 27 //添加Footer 28 jsonBuilder.Append(",\"footer\":["); 29 jsonBuilder.Append(footer); 30 jsonBuilder.Append("]}"); 31 32 jsonBuilder = jsonBuilder.Replace("\n", "").Replace("\r", ""); 33 return jsonBuilder.ToString(); 34 }
