从单选按钮检查值

Question

所以我昨晚有这个工作，这是一个10个问题的测验。我今天做了一些修改，现在当我点击检查答案时，如果答案是否正确，我已经失去了在jumbotron中显示的功能。继续下一个问题仍然删除并重新填充列表。只是检查问题答案的按钮被打破了。这是jsFiddle链接：

问题与您的i值在侦听器回调块中无效有关。您可以使用currentQuestion值来解决此问题，例如：

  $('#submit').on('click', function() {
    var answer = $('input[name="1"]:checked').val(); 
    if (answer == questionsArray[currentQuestion]['answer']) {
      correctAnswers++;
      $('.jumbotron').html(answer + "?<br><br> That's correct!  You have " + correctAnswers + " out of 10 correct!");
    } else {
      $('.jumbotron').html(answer + "? <br><br> Oh dear, that's so so wrong! You have " + correctAnswers + " out of 10 correct");
    }
    return false;
  });
