javascript - 将对象复制到具有特定条件的另一个对象

Question

默认对象是:

var employee = {
    'name': 'Hermione',
    'salary': 1000
};

我的问题是，如何使用这种格式将其复制到另一个对象？

var employee = {
    'Hermione': 1000
};

我试过:

for (var prop in employee) {
    console.log(prop, employee[prop]); // 'name' 'Hermione'
    // what next?
}

更新:

var employees = [];
employees.push({ 'name': 'name1', 'salary': 1000 });
employees.push({ 'name': 'name2', 'salary': 2000 });
employees.push({ 'name': 'name3', 'salary': 3000 });

我想要实现的目标:

var employees = [
    {'name1': 1000},
    {'name2': 2000},
    {'name3': 3000}
];

Answer 1

你有这些对象的数组吗？对于单个对象，情况相当简单:

var employee2 = {};
employee2[employee['name']] = employee['salary'];

或者对于现代浏览器:

var employee2 = {
    [employee['name']]: employee['salary']
};

对象数组:

var employees = [
  { name: 'name1', salary: 1000 },
  { name: 'name2', salary: 2000 },
  { name: 'name3', salary: 3000 }
];

var employees2 = employees.map(employee => ({[employee.name]: employee.salary}));

console.dir(employees2);

对于旧版浏览器:

var employees2 = employees.map(function(employee) {
     var result = {};
     result[employee['name']] = employee['salary'];
     return result;
});
