從所有鍵中洗掉下劃線前綴

我有如下所示的資料：

當它保存為 JSON 時，我想洗掉鍵中的下劃線。是否有捷徑可尋？

我曾嘗試修改此代碼以完成它但未成功： 在 js 物件鍵名稱中將點替換為下劃線

function removeLeadingUnderscores(obj) {
  _.forOwn(obj, (value, key) => {


    if (_.startsWith("_")) {
      const cleanKey = _.substring(1)
      obj[cleanKey] = value;
      delete obj[key];
    }

    // continue recursively looping through if we have an object or array
    if (_.isObject(value)) {
      return removeLeadingUnderscores(value);
    }
  });
  return obj;
}

由于您已經計劃保存為 JSON，您可以使用它的自然遞回特性和其 reviver 引數來回傳不帶下劃線的物件。將物件的條目映射到一個沒有前導的新物件_。

const arr=[{_sourceAddresses:[{_street1:"957 Heathcote Unions",_city:"Matteoside",_state:"Hawaii",_postalCode:"69680",_postalCodePlusFour:"7715",_country:"USA",_type:0,_updatedAt:"1991-03-10T22:34:27.000Z",_createdAt:"1970-07-24T09:34:12.000Z"}],_emails:[{_address:"[email protected]",_primary:!0}],_phoneNumbers:[{_number:"4612902836",_type:0,_carrier:"AT&T"}],_customFields:{},_active:!0,_firstName:"Haven",_lastName:"Runolfsdottir",_gender:"M",_sourceIndividualId:"c1126d05-0e5b-4da1-8535-e1061d4163ee",_sourceCampusId:"ae1e70d5-d8bf-4942-b9ea-3da5765e055f",_primaryContact:!0,_salutation:"Mrs.",_suffix:"DDS",_birthDate:"1989-02-16T10:06:25.000Z"},{_sourceAddresses:[{_street1:"5910 Langosh Burgs Apt. 281",_city:"West Katheryn",_state:"Arkansas",_postalCode:"49571",_postalCodePlusFour:null,_country:"USA",_type:0,_updatedAt:"1984-01-09T09:34:02.000Z",_createdAt:"1986-01-13T17:36:41.000Z"}],_emails:[{_address:"[email protected]",_primary:!0}],_phoneNumbers:[{_number:"0608405498",_type:0,_carrier:"Verizon"}],_customFields:{},_active:!0,_firstName:"Andreane",_lastName:"Kerluke",_gender:"F",_sourceIndividualId:"0726bfc2-56af-4e46-90ef-c0a286404334",_sourceCampusId:"86fdb656-7e29-4ace-a1c7-149db81c7f5e",_primaryContact:!0,_salutation:"Mrs.",_suffix:null,_birthDate:"1979-11-14T10:07:02.000Z"}];

const stringified = JSON.stringify(
  arr,
  (_, value) => {
    return value && typeof value === 'object' && !Array.isArray(value)
      ? Object.fromEntries(
          Object.entries(value)
            .map(([key, value]) => [key.slice(1), value])
        )
      : value;
  }
);

console.log(stringified);

如果某些屬性不以開頭_，則可以更改.slice(1)為.replace(/^_/, '')。

這是通過簡單的遞回邏輯保存洗掉下劃線的物件的簡化版本：

let savedJson: any = [];
renamingArray(obj); // obj is your object

function renamingArray(element: any){
  for(let element of obj)
    if (Object.prototype.toString.call(element) === '[object Array]') {
      renamingArray(element);
    else 
      renamingObject(element);
  }
} 

function renamingObject(obj: any){
  let keys = Object.keys(obj)
  for(let objectKey of keys){
    savedJson.push({ [objectKey.substring(1)]: obj[objectKey] }); 
  }
}

console.log(savedJson)
