Question

I have multipule files:

default.html

<script src="/js/global.js"></script>
<script src="/js/default.js"></script>

global.js:

var session_id=null;

default.js:

session_id = "stuffs";
console.log(session_id); //works

chatroom.html (iframe in default.html)

<script src="/js/global.js"></script>
<script src="/pages/chatroom/chatroom.js"></script>

chatroom.js:

console.log(session_id);//doesn't work. returns 

How can I get access to session_id in chatroom.js? Thanks for any help!

Answer 1

Try the following from within the iframe:

window.parent.session_id

also window.top should work if you have many nested iframes:

window.top.session_id
