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')
}
});
