遍历多维对象 [英] Traverse through multi-dimentional object

问题描述

我有一个多维对象:

var obj = {
    prop: {
        myVal: "blah",
        otherVal: {
             // lots of other properties
        },
    },
};

在不知道对象的任何属性名称或维数"的情况下，如何遍历整个对象?

How would one traverse the entire object, without knowing any of the property names or the number of "dimensions" in the object?

SO上还有两个与该主题相关的其他问题:

There are a couple other questions on SO that are related to the topic:

遍历Javascript对象属性
javascript遍历对象

问题在于两个答案都不完全是我想要的，因为:

The problem is that both answers are not quite what I am looking for, because:

a):第一个链接仅遍历对象的第一层.
b)第二个答案要求您知道对象键的名称.

a) The first link only iterates through the first layer in the object.
b) The second answer requires you to know the names of the object's keys.

推荐答案

递归:

function doSomethingWithAValue(obj, callback) {
  Object.keys(obj).forEach(function(key) {
    var val = obj[key];
    if (typeof val !== 'object') {
      callback(val);
    } else {
      doSomethingWithAValue(val, callback);
    }
  });
}
