Use setInterval to catch when the iframe location.href changed

Hi Experts,

I want to open the iframe url in the parent window when the iframe location.href change.
I also want to do this with the parent window.

So, I think I have to use the setInterval function to listen when the iframe.location.href has changed.
Then, I use this new location to load it inside the parent window.

But I need a little help to implement the javascript code.

Hope you see what I need.

Thanks in advance for your help.
