沫沫金：jQuery EasyUI DataGrid动态合并单元格解决方案

 jQuery EasyUI DataGrid根据字段动态合并单元格，使用自定义函数mergeCellsByField()在DataGrid的onLoadSuccess中调用。

自定义函数mergeCellsByField：

1. /** 
2.  * EasyUI DataGrid根据字段动态合并单元格 
3.  * @param tableID 要合并table的id 
4.  * @param colList 要合并的列,用逗号分隔(例如："name,department,office"); 
5.  */ 
6.    function mergeCellsByField(tableID,colList){ 
7.        var ColArray = colList.split(","); 
8.        var tTable = $('#'+tableID); 
9.        var TableRowCnts=tTable.datagrid("getRows").length; 
10.        var tmpA; 
11.        var tmpB; 
12.        var PerTxt = ""; 
13.        var CurTxt = ""; 
14.        var alertStr = ""; 
15.        for (j=ColArray.length-1;j>=0 ;j-- ) 
16.        { 
17.            PerTxt=""; 
18.            tmpA=1; 
19.            tmpB=0; 
20.             
21.            for (i=0;i<=TableRowCnts ;i++ ) 
22.            { 
23.                if (i==TableRowCnts) 
24.                { 
25.                    CurTxt=""; 
26.                } 
27.                else 
28.                { 
29.                    CurTxt=tTable.datagrid("getRows")[i][ColArray[j]]; 
30.                } 
31.                if (PerTxt==CurTxt) 
32.                { 
33.                    tmpA+=1; 
34.                } 
35.                else 
36.                { 
37.                    tmpB+=tmpA; 
38.                    tTable.datagrid('mergeCells',{ 
39.                        index:i-tmpA, 
40.                        field:ColArray[j], 
41.                        rowspan:tmpA, 
42.                        colspan:null 
43.                    }); 
44.                    tmpA=1; 
45.                } 
46.                PerTxt=CurTxt; 
47.            } 
48.        } 
49.    } 

函数mergeCellsByField调用：

1. function workerCount(){ 
2.     $('#coutTable').datagrid({ 
3.         title:'员工统计', 
4.         height:595, 
5.         nowrap: false, 
6.         striped: true, 
7.         fitColumns:true, 
8.         url:'<%=path%>/order.do?method=orderCount',   
9.         queryParams:{date:$('#date').datebox('getValue')}, 
10.         onLoadSuccess:function(data){ 
11.             if (data.rows.length>0) 
12.             { 
13.                 //调用mergeCellsByField()合并单元格 
14.                 mergeCellsByField("coutTable","department,position"); 
15.             } 
16.         }, 
17.         columns:[[ 
18.             {title:'编号',field:'number',width:120}, 
19.             {title:'姓名',field:'name',width:120}, 
20.             {title:'部门',field:'department',width:120}, 
21.             {title:'职位',field:'position',width:120} 
22.         ]], 
23.         rownumbers:true 
24.     }); 
25. }
