就我个人而言，重命名对象中的键而不实现额外的沉重插件和轮子的最有效的方法:

var str = JSON.stringify(object);
str = str.replace(/oldKey/g, 'newKey');
str = str.replace(/oldKey2/g, 'newKey2');

object = JSON.parse(str);

如果对象具有无效的结构，还可以将其封装在try-catch中。工作完美无缺:)

您可以将工作包装在一个函数中，并将其分配给Object原型。也许可以使用流畅的界面样式使多个重命名流动。

Object.prototype.renameProperty = function (oldName, newName) {
     // Do nothing if the names are the same
     if (oldName === newName) {
         return this;
     }
    // Check for the old property name to avoid a ReferenceError in strict mode.
    if (this.hasOwnProperty(oldName)) {
        this[newName] = this[oldName];
        delete this[oldName];
    }
    return this;
};

ECMAScript 5 Specific

我希望语法不是这么复杂，但它肯定是很好的有更多的控制。

Object.defineProperty(
    Object.prototype, 
    'renameProperty',
    {
        writable : false, // Cannot alter this property
        enumerable : false, // Will not show up in a for-in loop.
        configurable : false, // Cannot be deleted via the delete operator
        value : function (oldName, newName) {
            // Do nothing if the names are the same
            if (oldName === newName) {
                return this;
            }
            // Check for the old property name to 
            // avoid a ReferenceError in strict mode.
            if (this.hasOwnProperty(oldName)) {
                this[newName] = this[oldName];
                delete this[oldName];
            }
            return this;
        }
    }
);

虽然这并不是一个更好的重命名键的解决方案，但它提供了一种快速简单的ES6方法来重命名对象中的所有键，同时不改变它们所包含的数据。

let b = {a: ["1"], b:["2"]};
Object.keys(b).map(id => {
  b[`root_${id}`] = [...b[id]];
  delete b[id];
});
console.log(b);

尝试使用lodash transform。

var _ = require('lodash');

obj = {
  "name": "abc",
  "add": "xyz"
};

var newObject = _.transform(obj, function(result, val, key) {

  if (key === "add") {
    result["address"] = val
  } else {
    result[key] = val
  }
});
console.log(obj);
console.log(newObject);

在您最喜欢的编辑器中尝试一下

const obj = {1: 'a', 2: 'b', 3: 'c'}

const OLD_KEY = 1
const NEW_KEY = 10

const { [OLD_KEY]: replaceByKey, ...rest } = obj
const new_obj = {
  ...rest,
  [NEW_KEY]: replaceByKey
}

这是我对pomber函数做的一个小修改; 为了能够获取一个对象数组而不是单独的对象，你也可以激活索引。此外，“键”也可以由数组分配

function renameKeys(arrayObject, newKeys, index = false) {
    let newArray = [];
    arrayObject.forEach((obj,item)=>{
        const keyValues = Object.keys(obj).map((key,i) => {
            return {[newKeys[i] || key]:obj[key]}
        });
        let id = (index) ? {'ID':item} : {}; 
        newArray.push(Object.assign(id, ...keyValues));
    });
    return newArray;
}

test

const obj = [{ a: "1", b: "2" }, { a: "5", b: "4" } ,{ a: "3", b: "0" }];
const newKeys = ["A","C"];
const renamedObj = renameKeys(obj, newKeys);
console.log(renamedObj);
