来到这里(2022年)，寻找OP问题的近似变体。变化:

如何根据一个值找到一个对象键，其中键可以保存值的集合?

对于这个用例，从equal(===)切换到.includes():

const foo = ['a', 'b','c'];
const bar = ['x', 'y', 'z'];
const bat = [2, 5, 'z'];
const obj = {foo: foo, bar: bar, bat: bat};

const findMe = (v) => {
  return Object.keys(obj).filter((k) => obj[k].includes(v))
}

findMe('y') // ['bar']
findMe('z') // ['bar', 'bat']

我使用这个函数:

Object.prototype.getKey = function(value){
  for(var key in this){
    if(this[key] == value){
      return key;
    }
  }
  return null;
};

用法:

// ISO 639: 2-letter codes
var languageCodes = {
  DA: 'Danish',
  DE: 'German',
  DZ: 'Bhutani',
  EL: 'Greek',
  EN: 'English',
  EO: 'Esperanto',
  ES: 'Spanish'
};

var key = languageCodes.getKey('Greek');
console.log(key); // EL

下划线js解决方案

let samplLst = [{id:1,title:Lorem},{id:2,title:Ipsum}]
let sampleKey = _.findLastIndex(samplLst,{_id:2});
//result would be 1
console.log(samplLst[sampleKey])
//output - {id:2,title:Ipsum}

ES6方法:

Object.fromEntries(Object.entries(a).map(b => b.reverse()))['value_you_look_for']

保持简单!

你不需要通过复杂的方法或库来过滤对象，Javascript有一个内置的名为object .values的函数。

例子:

let myObj = {jhon: {age: 20, job: 'Developer'}, marie: {age: 20, job: 
'Developer'}};

function giveMeTheObjectData(object, property) {
   return Object.values(object[property]);
}

giveMeTheObjectData(myObj, 'marie'); // => returns marie: {}

这将返回对象属性数据。

真的很简单。

const CryptoEnum = Object.freeze({
                    "Bitcoin": 0, "Ethereum": 1, 
                    "Filecoin": 2, "Monero": 3, 
                    "EOS": 4, "Cardano": 5, 
                    "NEO": 6, "Dash": 7, 
                    "Zcash": 8, "Decred": 9 
                  });

Object.entries(CryptoEnum)[0][0]
// output => "Bitcoin"
