如何读取对象内部的每个对象并移至数组

Question

I have a requirement to move each object of object into array. My object looks like below

obj = { obj1: {}, obj2: {}, obj3: {}}

I need to convert each object into array and it should look like below

array[0] = obj1
array[1] = obj2
array[2] = obj3

Can someone please help me?

Answer 1

Use Object.values :

 const obj = {obj1: {foo: 'bar'}, obj2: {foo: 'baz'}} const result = Object.values(obj) console.log(result) 

Answer 2

From https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/values

The Object.values() method returns an array of a given object's own enumerable property values, in the same order as that provided by a for...in loop (the difference being that a for-in loop enumerates properties in the prototype chain as well).

const input = { obj1: {}, obj2: {}, obj3: {}};
console.log(Object.values(input));

(3) [{…}, {…}, {…}]

0: {}

1: {}

2: {}

length: 3

Answer 3

3 different methods

 const obj = { obj: { name: 'obj1' }, obj2: { name: 'obj2' }, obj3: { name: 'obj3' }} // option 1 const arr = [] for (let key in obj) arr.push(obj[key]) // option 2 const arr2 = Object.keys(obj).map(key => obj[key]) // option 3 const arr3 = Object.values(obj) console.log(arr) console.log(arr2) console.log(arr3) 

Answer 4

Simple as this

let obj = { obj1: {}, obj2: {}, obj3: {}}
console.log(Object.keys(obj).map(k => obj[k]))

Answer 5

const obj = {obj1: {foo: 'bar',foo1: 'bar1'}, obj2: {foo: 'baz'}}

var keyObj = Object.keys(obj);
var valueObj = Object.values(obj);
const newObj = [];
for(let i = 0;i < keyObj.length;i++) {
  var tmp = [];
  tmp[keyObj[i]] = valueObj[i]; 
  newObj.push(tmp);
}
console.log(newObj);
