       "ddid": "dd3", 
       "name": "third value" 
      }] 
     }] 
    }] 
} 

は、私が現在のオブジェクト

{ 
    "payload": [{ 
     "id": "idval1,idval3,idval6", 
     "type": [{ 
      "lists": [{ 
       "id": "1234", 
       "value": "One", 
       "ddid": "dd1", 
       "name": "first value" 
      }, 
      { 
       "id": "1235", 
       "value": "Two", 
       "ddid": "dd2", 
       "name": "second value" 
      }] 
     }] 
    }, 
    { 
     "id": "idval2,idval4,idval5,idval7", 
     "type": [{ 
      "lists": [{ 
       "id": "1234", 
       "value": "One", 
       "ddid": "dd1", 
       "name": "first value" 
      }, 
      { 
       "id": "1235", 
       "value": "Two", 
       "ddid": "dd2", 
       "name": "second value" 
      }, 
      { 
       "id": "1236", 
       "value": "Three", 
       "ddid": "dd3", 
       "name": "third value" 
      }] 
     }] 
    }] 
} 

から期待していたオブジェクトの集合である、次のように私の現在のオブジェクトがあるどのような方法にはありますアンダースコアまたはJavaScriptを使用してこれを達成します。

ご協力いただきありがとうございます。

Lodashを使用すると、_.uniqWithを使用して、一意性を見つけるためのカスタムコンパレータを使用できます。コンパレータの2番目のパラメータを変更すると、idを組み合わせることができます。

var obj = {"payload":[{"id":"idval1","type":[{"lists":[{"id":"1234","value":"One","ddid":"dd1","name":"first value"},{"id":"1235","value":"Two","ddid":"dd2","name":"second value"}]}]},{"id":"idval2","type":[{"lists":[{"id":"1234","value":"One","ddid":"dd1","name":"first value"},{"id":"1235","value":"Two","ddid":"dd2","name":"second value"},{"id":"1236","value":"Three","ddid":"dd3","name":"third value"}]}]},{"id":"idval3","type":[{"lists":[{"id":"1234","value":"One","ddid":"dd1","name":"first value"},{"id":"1235","value":"Two","ddid":"dd2","name":"second value"}]}]},{"id":"idval4","type":[{"lists":[{"id":"1234","value":"One","ddid":"dd1","name":"first value"},{"id":"1235","value":"Two","ddid":"dd2","name":"second value"},{"id":"1236","value":"Three","ddid":"dd3","name":"third value"}]}]},{"id":"idval5","type":[{"lists":[{"id":"1234","value":"One","ddid":"dd1","name":"first value"},{"id":"1235","value":"Two","ddid":"dd2","name":"second value"},{"id":"1236","value":"Three","ddid":"dd3","name":"third value"}]}]},{"id":"idval6","type":[{"lists":[{"id":"1234","value":"One","ddid":"dd1","name":"first value"},{"id":"1235","value":"Two","ddid":"dd2","name":"second value"}]}]},{"id":"idval7","type":[{"lists":[{"id":"1234","value":"One","ddid":"dd1","name":"first value"},{"id":"1235","value":"Two","ddid":"dd2","name":"second value"},{"id":"1236","value":"Three","ddid":"dd3","name":"third value"}]}]}]}; 
 

 
obj.payload = _.uniqWith(obj.payload, function(val, accVal) { 
 
    if (_.isEqual(val.type, accVal.type)) { 
 
    accVal.id += "," + val.id; 
 
    return true; 
 
    } 
 
    return false; 
 
}); 
 

 
console.log(obj);
