我有一个这样的对象数组：

"addresses": [
    {
      "addressOrgName": "ACME",
      "addressLine1": "1 BRAIDWOOD AVENUE",
      "addressLine2": "KNUTSFORD",
      "county": "CHESHIRE",
      "postCode": "WA1 1QP",
      "country": "UNITED KINGDOM",
      "type": "DELIVERY",
      "telephoneNumber" : "0151234533"
    },
    {
      "addressOrgName": "ABC SUPPLIES",
      "addressLine1": "UNIT 4 MILLENNIUM BUSINESS ESTATE",
      "addressLine2": "BRUNTWOOD",
      "county": "DEVON",
      "postCode": "D1 5FG",
      "country": "UNITED KINGDOM",
      "type": "COLLECTION"
    },
    {
      "addressOrgName": "EFG ELECTRICAL",
      "addressLine1": "UNIT 4 MILLENNIUM BUSINESS ESTATE",
      "addressLine2": "BRUNTWOOD",
      "county": "DEVON",
      "postCode": "D1 5FG",
      "country": "UNITED KINGDOM",
      "type": "RETURN"
    }
  ]

一或两个地址类型可能不存在，但总是带有type: DELIVERY的地址类型。我需要完成的是检查是否存在以及哪一个不存在，并将缺少的一个推入数组，因此结果数组将如下所示：

"addresses": [
    {
      "addressOrgName": "ADDRESSEE ONLY",
      "addressLine1": "1 BRAIDWOOD AVENUE",
      "addressLine2": "KNUTSFORD",
      "county": "CHESHIRE",
      "postCode": "WA1 1QP",
      "country": "UNITED KINGDOM",
      "type": "DELIVERY",
      "telephoneNumber" : "0151234533"
    },
    {
      "addressOrgName": "",
      "addressLine1": "",
      "addressLine2": "",
      "county": "",
      "postCode": "",
      "country": "",
      "type": "COLLECTION"
    },
    {
      "addressOrgName": "",
      "addressLine1": "",
      "addressLine2": "",
      "county": "",
      "postCode": "",
      "country": "",
      "type": "RETURN"
    }
  ]

不知道该如何处理。有想法吗？

谢谢

最佳答案

遍历每种需要的类型，如果找不到，则将其添加到数组中：

const addresses = [{
  "addressOrgName": "EFG ELECTRICAL",
  "addressLine1": "UNIT 4 MILLENNIUM BUSINESS ESTATE",
  "addressLine2": "BRUNTWOOD",
  "county": "DEVON",
  "postCode": "D1 5FG",
  "country": "UNITED KINGDOM",
  "type": "RETURN"
}
                  ];
const addTypes = ['DELIVERY', 'COLLECTION'];
addTypes.forEach((addType) => {
  const foundObj = addresses.find(({ type }) => type === addType);
  if (foundObj) return;
  addresses.push({
    "addressOrgName": "",
    "addressLine1": "",
    "addressLine2": "",
    "county": "",
    "postCode": "",
    "country": "",
    "type": addType,
  });
});
console.log(addresses);
