javascript - 如何更改 JS 对象键序列

Question

我想将对象键的顺序更改为给定的键。(首先是男性，然后是 child ，然后是女性)有一个对象:

const types = [
    {female: 100, male: 200, children: 150},
    {female: 100, male: 200, children: 150}
];

我从后端获取对象，我需要在我的应用程序前端将一系列键更改为 male, children, female。这个问题我没遇到过，试了好几种方法，都没成功。我将非常感谢任何帮助。对象字段的示例输出代码:

{types && (
  <ul>_.map(Object.keys(types), key => (
    <li key={_.uniqueId(`${key}`)}>
      <span>{key, types[key]}</span>
    </li>
  </ul>
)}

100 female
200 male
150 children

结论是这样的。需要改成:

200 male
150 children
100 female

非常感谢!

Answer 1

您可以使用 JSON.stringify(value[, replacer[, space]]) 格式化字符串并再次转换为 json

const types = [
    {female: 100, male: 200, children: 150},
    {female: 100, male: 200, children: 150}
];

var newjson = JSON.parse(JSON.stringify( types , ["male","female","children"]));
console.log(newjson);
