Question

function Person (name, age) {
  this.name = name;
  this.age = age;
}

var family = []

var people = {alice:40, bob:42, michelle:8, timmy:6};


for (var key in people) {
  family.push({key:people[key]})
}

console.log(family);

这不给我钥匙。它给予的关键＆＃39;为每个键。在数组中添加{key：value}对象的正确方法是什么？

更新基于下面的K3N解决方案，如果我们每次都从构造函数声明，这是我理解的最佳方法：

keys = Object.keys(people);
for (var i = 0; i < keys.length; i++) {
  family.push(new Person(keys[i], people[keys[i]]));
}

Answer 1

因为你的人物数组包含人的名字作为关键，而值是年龄（小心，好像你得到两个同名的人在时空中发生核反应......！）。

你可以这样做：

Answer 2

使用Bracket notation以便可以将密钥视为变量属性名称

for (var key in people) {
    var temp={};
    temp[key]=people[key]
    family.push(temp)
}

或Computed property name

for (var key in people) {
  family.push({[key]:people[key]})
}

在数组中添加键值对象对
