Anchor tag from iframe to parent cross-domain/cross-browser

I'm not sure if this is even possible, but can a link that lives inside of an iFrame (on another domain) be used to access an anchor on its parent page?

For example:

Parent url: http://www.parenturl.com

Parent DIV to be targeted: <div id="anchortag">

iFrame url: http://www.iframeurl.com

Link inside of iframe: <a href="http://www.parenturl.com#anchortag"></a>

This method seems to work as expected in FF and Chrome but does not in Safari or IE. IE simply refreshed the开发者_如何学Python page when the link is clicked.

Is there any documented reason as to why IE would refresh and why this approach doesn't work?
