[jQuery] Set #iframe height to "height of the window " - "height of the #wrapper"

[jQuery] Set #iframe height to "height of the window " - "height of the #wrapper"


As it says on the tin:
How do I set height of the element called #iframe to "height of the
window " - "height of the #wrapper div"?
I'd love to write:
#iframe.height = window.height - #wrapper.height
But I suppose jQuery isn't going to read my mind yet :)
