Answer 1

This little script snippet should work:

<script>
if (window !== top) top.location = window.location;
</script>

Also, you can prevent your pages from being loaded in an iframe by specifying a X-Frame-Options: DENY header. See https://developer.mozilla.org/en-US/docs/The_X-FRAME-OPTIONS_response_header for details.

Answer 2

Break out of frame script can be done if you compare the url of top frame to the current frame url:

if(window.top.location.href != window.href)
{
  window.top.location = window.href;
}
