ANSWER: I discovered that you can set the document domain in both pages to avoid the security error:
document.domain = "mydomain.com"
in the iframe src page as well as the parent page.

Question
Calling parent JS function from iframe (permission denied)
I have a page with an iframe. The src of the iframe has code that calls a javascript function on the parent (parent.myfunction();). It does that onClick.
When clicking, I get a Permission Denied error.
After some experimenting, I noticed that my iframe src begins with http://www.
I get the error if I omitted the "www" in the address bar. i.e. http://mydomain.com (that happens when you just type mydomain.com in the address bar).
If I type www.mydomain.com, I don't get the error.
My research uncovered that the permission error is when the iframe holds a page from a different domain -- for security reasons.
But, in my case, it is the SAME domain. But, one visitor might use the www and another might not. How do I make both instances work?
BTW, the message from Chrome's Inspect Object is: "Unsafe JavaScript attempt to access frame with URL"
Again problem goes away when the parent was loaded with www.
