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 onLoadSuccess: 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 }
