Использование сканера штрих-кода для сканирования 2D-штрих-кода, чтобы получить значения внутри штрих-кода. Он работает нормально, пока я не нашел систему, на которой он не работает. Поскольку я получаю ALT Codes (ASCII) в событии keydown вместо char.
Код, который я использовал для анализа отсканированного штрих-кода
var completeOGKeys = [];
$(document).on("keydown",function(e) {
completeOGKeys.push(e.key);
e.preventDefault();
e.stopPropagation();
var keyCode = (e.keyCode ? e.keyCode : e.which);
if(keyCode == 13){
console.log(completeOGKeys);
}
});
1-й выход системы, работающий как задумано

Проблема в том, что 2-ая система возвращает event.key как alt + numpad для ex. @ возвращается как Alt064
Почему это происходит во 2-й системе?
