i found this jsfiddle, that should show all keys pressed on the keyboard. The code looks fine, but it does not seem to work, at least on my keyboard: https://jsfiddle.net/HwR9N/3/
When i press all the arrow keys, only two of the keys get listed.
I work with a similar code, to create a javascript game, but i got the same problem there:
//List of all keys pressed or up
var keymap = [];
window.addEventListener("keydown",
function(e){
keymap[e.keyCode] = true;
checkCombinations(e);
},
false);
window.addEventListener('keyup',
function(e){
keymap[e.keyCode] = false;
},
false);
A strange thing is, that the WASD keys work all at the same time.
Does anybody know a different method, that works on every keyboard? I haven’t tried another keyboard yet. Im working on a HP Laptop. OS is Windows 10. Problem occurs in Chrome and Firefox.
Im thankfull for any advice.
Greets,
Florian
