我想通过对象键对对象数组进行分组，然后根据该分组创建一个新的对象数组。我在下面显示我的对象。
var oldArr=[
{
"_id":"5c407834953d7f420d56f866",
"allocated_to":"FIELD",
"zone":"NORTH",
"state":"DELHI",
"location":"NEW DELHI",
"customer_name":"REET INFOTECH",
"bank_name_of_customer":"YES BANK",
"cl_contract_id":"LAI-00016881",
"lk_loan_account_id":"LK0000015094",
"front_end_manager_name":"SONAL",
"area_collection_manager":"ASHIS JENA",
"installment_date":"",
"collection_manager":"",
},
{
"_id":"5c407834953d7f420d56f867",
"allocated_to":"FIELD",
"zone":"NORTH",
"state":"DELHI",
"location":"Sree Nagar",
"customer_name":"REET",
"bank_name_of_customer":"Corporate BANK",
"cl_contract_id":"LAI-00016881",
"lk_loan_account_id":"LK0000015094",
"front_end_manager_name":"SONAL",
"area_collection_manager":"ASHIS JENA",
"installment_date":"",
"collection_manager":"",
},
{
"_id":"5c407834953d7f420d56f868",
"allocated_to":"FIELD",
"zone":"EAST",
"state":"Odisha",
"location":"Bhubaneswar",
"customer_name":"REET",
"bank_name_of_customer":"PNB BANK",
"cl_contract_id":"LAI-00016881",
"lk_loan_account_id":"LK0000015094",
"front_end_manager_name":"SONAL",
"area_collection_manager":"ASHIS JENA",
"installment_date":"",
"collection_manager":"",
},
{
"_id":"5c407834953d7f420d56f890",
"allocated_to":"FIELD",
"zone":"EAST",
"state":"Assam",
"location":"Gawhati",
"customer_name":"REET",
"bank_name_of_customer":"SBI BANK",
"cl_contract_id":"LAI-00016881",
"lk_loan_account_id":"LK0000015094",
"front_end_manager_name":"SONAL",
"area_collection_manager":"ASHIS JENA",
"installment_date":"",
"collection_manager":"",
}
]
我需要制作一个新数组，该数组应按zone,state,location分组，格式如下。
newdata={
zone_list: [{
zone: NORTH,
state_list: [{
state: DELHI,
location_list: [{
location: NEW DELHI,
task_list: [{
user_pkId: 5c407834953d7f420d56f866,
front_end_manager_name: SONAL,
collection_manager: "",
area_collection_manager: ASHIS JENA,
loan_accounts_assigned: [{
allocated_to: FIELD,
lk_loan_account_id: LK0000015094,
cl_contract_id: LAI-00016881,
customer_name: REET INFOTECH,
customer_bank_name: YES BANK,
}]
}]
}]
},{
state: JK,
location_list: [{
location: Sree Nagar,
task_list: [{
user_pkId: 5c407834953d7f420d56f867,
front_end_manager_name: SONAL,
collection_manager: "",
area_collection_manager: ASHIS JENA,
loan_accounts_assigned: [{
allocated_to: FIELD,
lk_loan_account_id: LK0000015094,
cl_contract_id: LAI-00016881,
customer_name: REET INFOTECH,
customer_bank_name: Corporate BANK,
}]
}]
}]
}]
},{
zone: EAST,
state_list: [{
state: Odisha,
location_list: [{
location: Bhubaneswar,
task_list: [{
user_pkId: 5c407834953d7f420d56f868,
front_end_manager_name: SONAL,
collection_manager: "",
area_collection_manager: ASHIS JENA,
loan_accounts_assigned: [{
allocated_to: FIELD,
lk_loan_account_id: LK0000015094,
cl_contract_id: LAI-00016881,
customer_name: REET INFOTECH,
customer_bank_name: SBI BANK,
}]
}]
}]
}]
}]
}
我在下面提供我的代码。

var findata={'zone_list':zonelist};

但是上面的代码没有给出预期的输出。

您可以为所需的组和相关键采用数组，并采用迭代和递归的方法。
seq_cntchar[5+1]

下面的代码不能给您完整的正确结果，但是您应该更好地了解如何做。 .reduce（）的引用为：https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/Reduce
