Check if content is in an iframe?

Question

How would I check if the page is being loaded in an iframe? Also, could I make a page change the main URL to its own from within an iframe?

Answer 1

Both are possible and explained extensively in this post:

Keep in mind that these are not perfect solutions since the parent page can prevent you from doing these things using various methods (also discussed in the post).

Answer 2

To get the parent's tag/nodeName :

theParent = $(this).parent();
//alert(theParent[0].nodeName);
