Iframe Get/Post Data from Parent

Question

is it possible to have an iframe read post-data or get-data from the parent frame?

example: if my current URL is www.site.com/parent_frame.html?url=www.frame.com/nav1/nav2/child_frame.html

would the frame embedded in the parent site be able to be set to load www.frame.com/nav1/nav2/child_frame.html.

I have access to both domains, however cannot use anything other than html and javascript on the parent page. the child page has access to PHP, javascript, HTML.

I am aware of the security risk of putting a URL in the get/post data and obviously the child would have validation to confirm that the URL is within the proper scope before loading, I just simply need some advice/direction on if this is possible.

While this isn't setting anything in the GET/POST data it is a method to use JavaScript inside an iframe to access JavaScript within the parent frame/page.
