如何遍历以对象为成员的纯JavaScript对象？

问题：

How can I loop through all members in a JavaScript object including values that are objects. 如何遍历JavaScript对象中的所有成员，包括对象值。

For example, how could I loop through this (accessing the "your_name" and "your_message" for each)? 例如，如何循环浏览（分别访问“ your_name”和“ your_message”）？

var validation_messages = {
    "key_1": {
        "your_name": "jimmy",
        "your_msg": "hello world"
    },
    "key_2": {
        "your_name": "billy",
        "your_msg": "foo equals bar"
    }
}
