You can't refresh the inner document in there due to the single origin policy.

Have you tried changing the iframe's src property and adding a random GET string to force a reload?

This should work:

<iframe id="myiframe" src="http://google.com"></iframe>

document.getElementById("myiframe").src = "http://www.google.com?"+(+new Date());

You can only reload the current iframe href if it's for the same domain (single origin policy) with following code:

<iframe id="myIframe" src="http://yourdomain.com"></iframe>

document.getElementById('myIframe').contentWindow.location.reload(true);

or get the current href

var currentHref = document.getElementById('myIframe').contentWindow.location.href;

I think just by updating the hre/src will work. So on button click do as follows:

window.frames.iframeName.location.href = "new url"

My solution was to remove previous iframe and append new iframe with new src.
