如何使用浏览器中的提示来验证多个OTP？

Question

I want to use the snippet below to verify multiple OTPs . If one OTP is correct, the user should be asked the next question. After 4 questions, show greetings.

var question = prompt('Who shot Abraham Lincoln?');

switch (question) {
    case 'john wilkes booth':
    case 'John Booth':
    case 'John Wilkes Booth':
        alert("That\'s Right!"); 
        window.location.href = 'q2.html'; 
        break;

    default:
        alert("Sorry, that\'s not right.");
        alert('Please try again');
        history.refresh();
        break;
}

Need help to re-build the code above.

Answer 1

Solution below

 var verificationStatus = 'unverified'; function questionnaire(questions, answers) { // Proceed only if # of questions and answers are equal if (questions && answers && questions.length === answers.length) { questions.forEach(function(question, index) { // Prompt only if verificationStatus has not been marked false already if (verificationStatus !== false) { var userInput = prompt(question); switch (userInput) { case answers[index]: verificationStatus = true; break; default: verificationStatus = false; break; } } }); } if (verificationStatus) { alert('Greetings, Verification Successful'); } else { alert('Sorry, Verification Failed'); } } // Please note # of questions and answers must be equal questionnaire(['Q1', 'Q2', 'Q3', 'Q4'], ['1', '2', '3', '4']); 

Behaviour

• The snippet above asks 4 questions, to which answers are 1, 2, 3, 4 respectively.
• If at any point, wrong answer is given, no more questions are asked.
• A message (greetings) is displayed at the end.

Hope it helps!
