The main difference between the two pages is the method of sending messages. Recieving messages is the same in both.
Send messages to iframe using iframeEl.contentWindow.postMessage
Recieve messages using window.addEventListener('message')

In this short guide we'll review some new Chrome DevTools features for "function scope" and "internal properties" by exploring some base JavaScript language concepts.
Let's start with closures – one of the most famous things in JS. A closure is a function, that uses variables from outside. See an example:
$(function () { | |
"use strict"; | |
// for better performance - to avoid searching in DOM | |
var content = $('#content'); | |
var input = $('#input'); | |
var status = $('#status'); | |
// my color assigned by the server | |
var myColor = false; |
if ($request_uri = /) { | |
set $test A; | |
} | |
if ($host ~* teambox.com) { | |
set $test "${test}B"; | |
} | |
if ($http_cookie !~* "auth_token") { | |
set $test "${test}C"; |
module Where | |
class <<self | |
attr_accessor :editor | |
def is_proc(proc) | |
source_location(proc) | |
end | |
def is_method(klass, method_name) | |
source_location(klass.method(method_name)) |
