Clipboard in any browser?

Question

Clipboard

Lord! Is it possible now to copy something to the clipboard on the client side using JS or other than Flash?
Interested in a solution for most browsers, including mobile ones. Of course, I heard that this is prohibited by browser policy, but I heard it a long time ago, i.e. everything could change.

Answer 1

You can, but IE will pop up a clipboard access warning.
