How to break iframe and redirect page with Jquery

Question

How can i understand that my page is being called from iframe and break it with jquery ? Thank you.

Answer 1

if (self !== top)
    top.location.replace(self.location.href)

that's how you break out of a frame

Answer 2

This can be done in plain Javascript since top and location are both objects attached to the global window object provided in all major browsers.

if (top.location != location){
    location.href = 'http://google.com';
}
