You either:
a. Have a bad keyboard,
b. Have some external code from some library or somewhere else in
your page or application that is catching a d keypress and preventing
the event from bubbling.
So,
-
It certainly has nothing to do with the code you posted (see zerkms’ comment), and
-
If you want it resolved, you will either have to post more code, or start debugging the code we cannot see. Do a process of elemination. Delete everything else in your page. Does it still not work? Play around. You won’t get any more insight here with what you have posted.
