如何在打字稿中的对象中动态获取ID值

Question

我有一个关于如何在打字稿中的对象中动态获取id值的问题。我可以举一个例子：

输入对象如下：

station = {
  id: "123123",
  address: {
    id: "asdfasd",
    type: "street"
    value: "asdfas"
  },
  station: {
    id: "asdsdfsdfasd",
    type: "trainstation"
    value: "asdfsdfsas"
  },
  information: {
    id: "asdsdfsdfasd",
    school: {
      id: "asdsdsdsfsdfasd",
      type: "middleschool"
      value: "asdfssdsddfsas"
    }
  }
}

如何动态获取父ID，如果给我一个诸如“ shool”的参数，那么我可以获得信息ID？

任何解决方案

Answer 1

这是您要寻找的东西吗？

const station = {"id":"123123","address":{"id":"asdfasd","type":"street","value":"asdfas"},"station":{"id":"asdsdfsdfasd","type":"trainstation","value":"asdfsdfsas"},"information":{"id":"asdsdfsdfasd","school":{"id":"asdsdsdsfsdfasd","type":"middleschool","value":"asdfssdsddfsas"}}};


function getId(obj, key){
let id;
Object.keys(obj, key).forEach(x=>{
if(x == key){
 id = obj[x].id; return id;
}
else{
if(typeof(obj[x]) == 'object'){ id = getId(obj[x], key)};
}
});
return id;
};

console.log(getId(station, 'school'));
