I just noticed that top, window and parent variables are giving me the same value. I was testing this at gmail inbox page. Does anybody know what is the difference between these three values?

If you are within a frame:

window refers to the current frame.

parent refers to the parent of the current frame.

top refers to the outermost frame.

If you're not within any frame, these will all just be a reference to the current window. If you're only within one level of frame, parent and top will both be a reference to the same thing.
