how to update iframe src from viewmodel

[Patrick Beagan]

I'm trying to update an iframe from knockout and having difficulties getting it to work.  I can successfully give the iframe an initial src value,  but  I can't  subsequently update it from a function.  here is the fiddle: http://jsfiddle.net/patrickb323/LXYSM/25/

I'm a newbie to JavaScript/knockout.  thanks for the help!

This is not a knockout issue but a security issue.

Google.com uses the x-frame-options HTTP response header to limit who can "frame" their pages (and Google sets the value to SAMEORIGIN meaning only Google.com can iFrame its pages):

https://developer.mozilla.org/en-US/docs/HTTP/X-Frame-Options

If you use Chrome and open up Chrome's developer tools (F12), look at the Console tab when running your fiddle.  it displays an error message when your viewmodel tries to update the src:

Refused to display 'https://www.google.com/' in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'.

So, your code works fine, but security reasons prevent you from using google.com as your iframe source.
