I am loading external javascript code to iframe with

<iframe id="myframe" src="http://external.tld/code"></iframe>

output from "external.tld/code" is:

var myvar="";
function something(){}

now I need to get this code as a plaintext to javascript variable in my main window. How? I tried document.getElementById('myframe').contentWindow.document.body.innerHTML but is is not working.

you can't do that as javascript, thankfully, does not allow such cross origin shenanigans – Jaromanda X Feb 28 '16 at 11:45
@JaromandaX — Well, you can, so long as external.tld co-operates. – Quentin Feb 28 '16 at 11:53
@Quentin - then it's not a shenanigan :p – Jaromanda X Feb 28 '16 at 11:54
and how please? I just need to get html code in plaintext, so myvar should be just html text and not javascript code anymore. (or maybe to use another way and not iframe) – peter Feb 28 '16 at 11:56
