How to remove iframe from parent page using a function inside the iframe?

Question

I have an iframe I put on a page using a bookmarklet, I want this iframe to close itself when I navigate to a certain page inside this iframe.

How to do that using JavaScript?

Note: iframe and container page are in different domains.

Answer 1

As far as I know you cannot remove the element from the DOM from the iframe's container unless it's the same domain if I'm understanding you properly due to cross-domain security policies.

If this were possible you could infiltrate bank sites and all, it'd be a mess.
