Question

Any way to tell if current frame is parent?

Answer 1

+3 A:

Greetings,

I found this pdf to be very useful : http://seclab.stanford.edu/websec/framebusting/framebust.pdf

In short, if this is too long to read, this is what they ultimately propose :

<style>
  html { display :none; }
</style>
<script>
if(self==top){
  document.documentElement.style.display = 'block';
}else{
top.location=self.location;
}
</script>

You will find many other means to do this in this pdf and each means' pro and cons. Obviously, on browsers without javascript, this solution could be painful ;)

self === top
