How to make difference between question mark ? and / for azerty keyboard

Question

When I bind the ? and the / key with javascript on qwerty keyboard they have the same keycode (191) but you have to press shift to do a ?.

How can I tell which character was pressed on an azerty keyboard (layout shown below), as they're different keys, both require Shift, and I get the same keycode for them in keyup.:

 $(document).keyup(function(event) { if (event.which === 191) { action(); } });

Qwerty is not a keyboard layout: is family of several dozen layouts. You should mention at least which country you mean. — Álvaro González

This is easy, you either bind to the keypress event instead, which will give you different keycodes, or you check event.shiftKey — adeneo

Use the keypress event

$(document).keypress(function(event) { if (event.which === 666) { action(); } });

I don't have an azerty keyboard or whatever, so I don't get the same keycodes, but the keypress event will return other keycodes, you'll have to check them yourself.

The Keycodes are stored in the event. Why do they have different keycodes for the same key? Can you explain please..

adeneo Over a year ago

keyup and keydown return different keycodes than keypress, so using the keypress event will return two different keycodes for the two characters, solving the issue.

Wouldn't event.charCode be more reliable?

@JuanMendes - jQuery normalizes event.which, so not really.

Check if shift is pressed

$(document).keyup(function(event) { if (event.which === 191 && event.shiftKey) { action(); } });

Note that this is keyboard layout dependent and it will be easier if you can use the keypress event as https://stackoverflow.com/a/24995506/227299 suggested

Yes but this with an azerty keyboard works for "?"and "/". Is there a solution to make a difference ? And thanks for your answer
