Check if a page is loaded in an iframe using Javascript

I am across this solution today after some head scratching. The solution turned out to be quite simple. To do the check just use the follow code:

var isInIFrame = (window.location != window.parent.location) ? true : false;
And that is it. This will work for all cases as long as your are not loading a page in an iframe of it self, which may possibly cause an infinite loop, you are fine. I have tested this in Firefox 3, Chrome 1.x and Internet Explorer 7.
