在另一个json对象（不是数组）中获取json对象

Question

i got this structure:

{
"parent": {
      "child-parent-1": {
            "att1": null,
            "att2": null,
      },
      "child-parent-2": {
            "att1": null,
            "att2": null,
      }
 }}

What i need to get, is the "child-parent-1" and "child-parent-2" names without knowing their names... since they are dynamically generated, like a hash code (askdl1km2lkaskjdnzkj2138).

Tried iterating but i couldn't make it work. I always get the child attributes (key/value pair). Or the entire parent object with all the objects in it. Need to get the parent names i've mentioned above.

How can I do this?

Thanks in advance.

Iterating the object should work:

var parents = {
    "parent": {
        "child-parent-1": {
            "att1": null,
            "att2": null,
        },
        "child-parent-2": {
            "att1": null,
            "att2": null,
        }
    }
}

for(var key in parents.parent){       // parents.parent because the children are in a object in `parents`
    console.log(key);                 // child-parent-1 / child-parent-2
    console.log(parents.parent[key]); // The objects themselves.
}

For me, this logs:

// child-parent-1
// Object {att1: null, att2: null}
// child-parent-2
// Object {att1: null, att2: null}
