     }] 
    }, 
    { 
     "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" 
      }] 
     }] 
    }] 
}

下面是对象集合，我从当前对象

{ 
    "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" 
      }] 
     }] 
    }] 
}

期待有什么办法使用下划线或JavaScript实现此目的。

感谢您的帮助提前。

您应该说明的是关于第二个数据集是唯一的。现在，我必须几乎猜到要理解第二个数据集中您想要的内容。 – KevBot

另外，你有没有尝试过吗？就目前而言，您只是要求社区成员为您工作。 – George

使用Lodash，您可以使用_.uniqWith为查找唯一性提供自定义比较器。在比较器中改变第二个参数可以让您组合id s。

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);

嗨，感谢您的帮助。是否有任何方法来检查**“列表”**，因为我们有一些名为**“ddtype”的类型的其他属性：“cs”**“”type“：[{”ddtype“：”cs“， “列表”：[{“id”：“1234”，“value”：“One”，“ddid”：“dd1”，“name”：“first value”}]}]'。该属性具有不同的值，所以我们无法使用类型。请给我建议。 – Karthikeyan

您可以在问题中编辑输入数据以显示吗？我不确定我明白。这听起来很简单，只需更改'_.isEqual'比较的内容即可。 – 4castle

感谢您的更新。我得到了解决办法。 :) – Karthikeyan
