parent.location.reload in iframe not working IE

Question

I need refresh in parent site / refresh my browser when I click testing. I have source index.php:

<iframe id="test" src="/careertest/q.php"></iframe>

and in q.php:

<a href="#" onclick="parent.location.reload(true);">testing</a>

Its working in FF LAtest version + Chrome but not working in IE 9.

He said "script70 :Permission denied."

I am already change

parent.location.reload(true)

with:

window.parent.location =window.parent.location.href;

or

document.domain=document.location.href;

but still not working...

Answer 1

use this function

function reloadParentPage() {
    var selfUrl = unescape(parent.window.location.pathname);
    parent.location.reload(true);

    parent.window.location.replace(selfUrl);

    parent.window.location.href = selfUrl;
}
