js去重合并

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;

}

}

}

}
