1，首先，写方法将问题类型和派单方式里面的所有的字段内容找到，完成后台方法
2,在js，使用datagrid方法时，将columns指向一个function
basicReport=$('#basicReport').datagrid({
...............
....................
columns:fetchBasicColumns(),
........................
.............
});
3,书写function fetchBasicColumns(){
var columnsOne = new Array();
var columnsTwo = new Array();
$.ajax({
type : "POST",
url : "XXXXXXXXX",
datatype : "json",
async: false,
success : function(data) {
var data = $.parseJSON(data);
columnsOne.push({title: 'A', field: 'time',rowspan:2});
columnsOne.push({title:"B",colspan:data.queTypeColumns.length});
columnsOne.push({title:"C",colspan:data.sendWayColumns.length});
columnsOne.push({title: 'D', field: 'avgTime',rowspan:2});
columnsOne.push({title: 'E', field: 'countAll',rowspan:2});
$.each(data.queTypeColumns,function(i,item){
columnsTwo.push({"title":item,"field":"queType"+i,rowspan:1,width:50});
});
$.each(data.sendWayColumns,function(i,item){
columnsTwo.push({"title":item,"field":"sendWay"+i,rowspan:1,width:50});
});
}
});
return new Array(columnsOne,columnsTwo);
};
多表头模板写法：[ [{title: 'A', field: 'time',rowspan:2,width:'15%'},
{title:"B",colspan:3,width:'30%'},
{title:"C",colspan:3,width:'30%'},
{title: 'D', field: 'avgTime',rowspan:2,width:'15%'},
{title: 'E', field: 'countAll',rowspan:2,width:'10%'}],
[{title:"XXXXX",field:"X",rowspan:1,width:50},
{title:"XXX",field:"X",rowspan:1,width:50},
{title:"XXX",field:"X",rowspan:1,width:100},
{title:"XXXXX",field:"x",rowspan:1,width:50},
{title:"XXXX",field:"X",rowspan:1,width:50},
{title:"xXXX",field:"X",rowspan:1,width:50}]
]
4. 后台书写datagrid访问的方法
@SuppressWarnings("unchecked")
@RequestMapping(value="/XXXXXXXX")
@ResponseBody
public List<JSONObject> setWeekData(@RequestParam(value="time",required=false) String time){
。。。。。。。。。。。。。。。。。。。。。。
Map<String,Object>basicColumns=reportService.fetchBasicColumns();
List<String> queTypeColumns=(List<String>) basicColumns.get("queTypeColumns");
List<String> sendWayColumns=(List<String>) basicColumns.get("sendWayColumns");
List<JSONObject> result=new ArrayList<>();
List<Map<String, Object>> queType = reportService.findQueType(wd);
List<Map<String, Object>> sendWay = reportService.findSendWay(wd);
List<String> queTypeColumnList=new ArrayList<String>();
List<String> sendWayColumnList=new ArrayList<String>();
for(String queTypeColumn : queTypeColumns){
String queTypeNumber="0";
for (Map<String, Object> map : queType) {
if(queTypeColumn.equals((String)map.get("typeName"))){
queTypeNumber=(String)map.get("cnt").toString();
}
}
queTypeColumnList.add(queTypeNumber);
}
for(String sendWayColumn : sendWayColumns){
String sendWayNumber="0";
for (Map<String, Object> map : sendWay) {
if(sendWayColumn.equals((String)map.get("typeName"))){
sendWayNumber=(String)map.get("cnt").toString();
}
}
sendWayColumnList.add(sendWayNumber);
}
Long avgTime = reportService.findAvgTime(wd);
Long countAll = reportService.countAll(wd);
jsonObj.put("avgTime", avgTime!=null?avgTime:0);
jsonObj.put("countAll", countAll!=null?countAll:0);
for(int i=0;i<queTypeColumnList.size();i++){
jsonObj.put("queType"+i, queTypeColumnList.get(i));
}
for(int i=0;i<sendWayColumnList.size();i++){
jsonObj.put("sendWay"+i, sendWayColumnList.get(i));
}
jsonObj.put("time", year+"年"+week+"周");
result.add(jsonObj);
return result;
}
