如何以对象为成员循环遍历纯 JavaScript 对象

javascript

如何遍历 JavaScript 对象中的所有成员,包括作为对象的值?

例如,我怎样才能遍历这个(访问每个“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"
    }
}

for (var key in validation_messages) {
// skip loop if the property is from prototype
if (!validation_messages.hasOwnProperty(key)) continue;

var obj = validation_messages[key];
for (var prop in obj) {
    // skip loop if the property is from prototype
    if (!obj.hasOwnProperty(prop)) continue;

    // your code
    alert(prop + " = " + obj[prop]);
}

}
