How to loop through a plain JavaScript object with the objects as members

Question

How can I loop through all members in a JavaScript object, including values that are objects?

For example, how could I loop through this (accessing the "your_name" and "your_message" for each)?

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

Answer 1

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]);     } }
