Parsing JSON with jQuery

Question

I've got this JSON object:

({a1:-1,a2:null, messages:[{b1:message1, b2:message2, b3:message3, ... }]})

How do I loop through the messages pairs using jQuery's .each (without hardcoding the b1,b2,b3,message1,message2,message3).

It's also worth stating that there is no such thing as a "JSON object"! JSON is by definition a string. As soon as it ceases to be a string, it's just a JavaScript object! — Adam Terlson

Assuming data is your object, you can use $.each for this.

var messages = data.messages;
$.each(messages, function(i, msg){
   $.each(msg, function(key, message){
      console.log(key+': '+message);
   });
});

Start by reading the reference for jQuery.each(). Here's an apt example from the reference:

$.each({ name: "John", lang: "JS" }, function(k, v) {
    alert( "Key: " + k + ", Value: " + v );
});

Thanks for your response. Sometimes it just takes an example to make it click. I realize now that I needed a nested each. Very cool.
