如何用新的替換 json object 的屬性

Question

此 object 生成取決於來自后端的自定義字段。 需要一個 function 來替換新的和其他刪除的某些字段或不包括在提交 object

 {
    "originating_office": {
      "code": "string", **replace on "value": "string",**
      "description": "string" **replace on "label": "string"**
    },
    "petty_cash_account": {
      "number": "string", **replace on "value": "string",**
      "name": "SOME DATA", **replace on "value": "string",**
      "gls_account": "SOME DATA-HERE", **just add new filed**
      "currency": "SOME", **just add new filed**
      "origination_office_of": "" **just add new filed**
    },
    "item": "simple string",
    "amount": "0.7",
    "spending_unit": {
      "indexno": "08805544", **save**
      "display_name": "Mark Twen", **delete**
      "position_title": null, **delete**
      "org_unit_name": "", **delete**
      "extension": null, **delete**
      "country": "Italy", **delete**
      "duty_station": "2250", **delete**
      "email": "user@example.com", **save**
      "last_name": "Some", **save**
      "first_name": "Data", **save**
      "username": "some.data", **delete**
      "text": "Some DATA" **save**
    },
  }

但無法想象前進的方向

const replaceDataByNew = (obj) => {
  for (let i = 0; i < obj.length; i++) {
    if (obj[i].hasOwnProperty('originating_office')) {
      console.log("originating_office");
      
    }
    if (obj[i].hasOwnProperty('cash_collected')) {
      console.log("cash_collected");
    }
  }
};

replaceDataByNew(data);

我嘗試重構下一種方法： 替換 JSON 中的屬性值，但不幸的是。 如果你幫助我，我將不勝感激

如果您想要的更改非常具體，您知道要更改的每個字段，您可以修改每個屬性。 如果上面的 object 在變量 x

let x = {
  originating_office: { code: "string", description: "string" },
  petty_cash_account: {
    number: "string",
 and so on

你可以簡單地做到這一點。

//This modifies the value of code to "A new string"
x.originating_office.code = "A new string";    
//This deletes the display_name property on the spending unit property
delete x.spending_unit.display_name;
//You can also reference properties using this format
delete x["spending_unit"]["display_name"];
//Javascript is dynamic, you add a new property like this.
x.petty_cash_account.currency = "USD";

如果要遍歷 object 的所有屬性，請使用 Object.values

Object.values(x).forEach((key,val)=>console.log(key,val))
