Answer 1

In non-IE browsers, you want the which or charCode property in a keypress event rather than the keyCode property. The keypress event is for detecting typed characters while keyup and keydown are for detcting physical keys (in those events, keyCode works in every major browser).

var charCode = (typeof event.which == "number") ? event.which : event.keyCode;

However, jQuery normalizes the which property of keypress events by using code similar to this, so in jQuery you just need

var charCode = event.which;

For (a lot) more detail about key events, see http://unixpapa.com/js/key.html.
