Estoy tratando de crear una validación de pin en javascript. Quiero pedirle al usuario un pin y ellos ingresan 1234. Si ingresan el pin incorrecto 3 veces, quiero que diga el mensaje "pin incorrecto. Póngase en contacto con el banco". Gracias por cualquier ayuda
function pinCode() { const Pin = "1234"; {} const name = prompt("Please enter your full name"); const user_Attempt = prompt("Please enter your PIN number to access your bank account"); if (user_Attempt = Pin) { alert("Welcome" + name); } else { alert("Incorrect pin. Please contact your bank"); return; } }Tal vez use la recursividad para esto
var incorrectCount = 0; function pinCode() { if (incorrectCount != 3) { // prompts here if (user_Attempt === Pin) { // do stuff } else { incorrectCount += 1; pinCode(); } } else { // code for too many incorrect tries } } const pin = "1234"; let attemptsLeft = 3 const name = prompt("Please enter your full name"); for (attemptsLeft; attemptsLeft >= 0; attemptsLeft--) { if (attemptsLeft === 0) { alert("Incorrect pin. Please contact your bank"); break; } const userAttempt = prompt(`Please enter your PIN number to access your bank account. You have ${attemptsLeft} left.`); if (userAttempt === pin) { alert("Welcome " + name); break; } }Use un ciclo while para seguir repitiendo hasta que se agoten los attempts o pinCorrect sea true .
const correctPin = '1234'; const maxAttempts = 3; let attempts = 0; let pinCorrect = false; while (attempts < maxAttempts && !pinCorrect) { const pinInput = prompt(`Please enter your PIN number to access your bank account. ${maxAttempts - attempts} attempts left.`); pinCorrect = pinInput === correctPin; attempts++; } if (!pinCorrect) { alert('Incorrect pin. Please contact your bank'); } else { alert('Pin accepted'); }
