const login = prompt("Enter username!", "");
if (login === "Admin") {
prompt("Enter password!");
} else if (login === "" || login.keyCode === 27) {
alert("Canceled");
} else {
alert("I don't know you!");
}This is the error message when I press Esc:
'Cannot read properties of null (reading 'keyCode') at logical-operators.html:77'
when you press ESC the login value will become null so you can check like this:
if(!login){
alert('cancled')
}
or you can add listener to dom if ESC clicked :
document.addEventListener("keyup", (e) => {
if (e.key === "Escape") {
// escape key maps to keycode `27`
alert('cancled')
}
});
