设置嵌套对象值 [英] Setting a nested object value

问题描述

我有以下对象：

var object = {
    "property1": "value1",
    "property2": "value2",
    "subobject": {
        "property1": "value1",
        "property2": "value2",
        "subobject": {
            "property1": "value1",
            "property2": "value2",
            "subobject": {...
            }
        }
    }
}

我试图设置一个嵌套的子对象属性，但嵌套级别是动态的。

I am trying to set one of the nested subobject properties, but the nested level is dynamic.

如何在不执行此操作的情况下动态设置其中一个嵌套属性： object.subobject.subobject = {...} ？

How can I dynamically set one of these nested properties without doing something like this: object.subobject.subobject = { ... }?

编辑：
所以更具体一点，我正在尝试设置一个嵌套的子对象，但我不会每次都知道哪一个。

So to be more specific, I am trying to set one of the nested subobjects, but I won't know which one each time.

推荐答案

让我们使用递归！

function setNest(obj, level, val){
    if(level > 0){
        setNest(obj.subobject, level-1, val);
    }
    else{
        obj.subobject = val;
    }
}

然后称之为：

setNest(object, 2, {a: 12});
