如何为测验应用程序创建重启按钮？

Question

This is a sample I got from the web. I want to create a restart button for the quiz. How am I suppose to do that? If possible, please include a Codepen demo too. Thank you !!

Codepen Demo

var all_questions = [{
  question_string: "What is my name?",
  choices: {
    correct: "James",
    wrong: ["John", "Bob", "Jeff"]
  }
}]

Answer 1

Add below lines after submit button click event.

// Add listener for the restart button
$('#restart-button').click(function() {
  current_question_index = 0;
  change_question();
});
