使用对象

Question

我有一个像这样的对象：

var days = {
  0: 10,
  1: 40
  2: 20, 
  3: 15,
  4: 5,
  5: 18, 
  6: 9
};

我需要将其转换为类似的东西：

var days2 = [
  {0:10},
  {1: 40},
  {2: 20},
  {3: 15},
  {4: 5},
  {5: 18},
  {6: 9},
];

我知道这很容易，但我不知道

Answer 1

您可以获取对象的所有条目，并使用键/值对构建新对象。

＆＃13;

var days = { 0: 10, 1: 40, 2: 20, 3: 15, 4: 5, 5: 18, 6: 9 },
    result = Array.from(Object.entries(days), ([k, v]) => ({ [k]: v }));
    
console.log(result);

Answer 2

您可以使用Object.keys和map

 Object.keys(days).map( key => {return { [key]: days[key] 

var days = {
  0: 10,
  1: 40,
  2: 20, 
  3: 15,
  4: 5,
  5: 18, 
  6: 9
};
var output = Object.keys(days).map( key => {return { [key]: days[key] } });

console.log(output);
