1.去重

for(var q = 0;q<jsonArr.length;q++){
 
 for(var e=0;e<jsonArr[q].data.length;e++){
 
 var matchCode = jsonArr[q].data[e];
 var chua = jsonArr[q].jsonObj;
 var isExist = false;
 var isC = false;
 //去重多少场次
 for(var m = 0; m < an.length; m ++){ 
 
 if(jsonArr[q].data[e].mhcode == an[m].mhcode && jsonArr[q].data[e].jackpot==an[m].jackpot &&
 jsonArr[q].data[e].option == an[m].option){
 isExist = true;
 break;
 } 
 }
 //去重几串几
 for(var r=0;r<jso.length;r++){
 if(jsonArr[q].jsonObj.e0 == jso[r].e0 && jsonArr[q].jsonObj.e1 == jso[r].e1){
 
 isC = true;
 break;
 } 
 }
 if(!isExist){
 an.push(matchCode);
 }
 if(!isC){
 jso.push(chua);
 } 
 
 } 
 }
 
2合并
 var s = new Array();
 for(var e=0;e<an.length;e++){ 
 var matchCode = an[e];
 
 var isExist = false;
 for(var m = 0; m < s.length; m ++){ 
 if(matchCode.mhcode == s[m].mhcode && matchCode.jackpot==s[m].jackpot ){
 s[m].option +=","+matchCode.option;
 isExist = true;
 break;
 }

                 }
                 if(!isExist){
                  s.push(matchCode);
 
                 }        
            }
3.分组
 var map = {},
 dest = [];
 
 for(var i = 0; i < s.length; i++){
 var ai = s[i];
 
 if(!map[ai.mhcode]){
 dest.push({
 mhcode: ai.mhcode,
 jk:ai.jackpot,
 
 data: [ai]
 });
 map[ai.mhcode] = ai; 
 }else{
 for(var j = 0; j < dest.length; j++){
 var dj = dest[j]; 
 if(dj.mhcode == ai.mhcode ){ 
 dj.data.push(ai);
 break;
 }
 }
 }
 }
