如何知道检查哪些单选按钮并正确重定向

Question

我正在为一家用户回答三个问题的公司进行测验，如果他们都是正确的，他们应该被重定向到一个页面，在那里他们填写他们的联系信息，以便有机会赢得奖品。 如果一个或多个问题的回答错误，则应将其重定向到另一个页面。

我需要标记正确的答案，然后检查它们。 如果所有问题都得到了正确回答：重定向到motivering.html 如果一个或多个问题出错：重定向到tyvarr.html

我试图检查这些值，然后才想出来。这不正确，我几乎可以肯定它不是最合适的方式。

的jQuery

$(document).ready(function() {
    $('#questions input').on('change', function() {
       console.log($('input[name=questionOne]:checked', '#questions').val());
       console.log($('input[name=questionTwo]:checked', '#questions').val());
       console.log($('input[name=questionThree]:checked', '#questions').val());
    });
});

＆＃13;

对于重定向而不是打印＆＃39;发现错误答案！＆＃39;或者＆＃39;所有答案都是正确的！＆＃39;在控制台中，你会这样做：

  //Check if all answers are rightAnswers
  for(var i = 0; i < userAnswers.length; i++){
    if(userAnswers[i] != rightAnswers[i]){
      window.location.href = 'wrong.html';
      return; // End here, and do not execute further redirection.
    }
  }

  window.location.href = 'right.html';

return内部循环确保脚本将在那里结束函数执行，并且它不会执行＆＃39; right.html＆＃39;重定向。

这两个循环，用于检查答案是否已定义，以及它们是否正确可以合并为一个，但是还有一些代码会注意到所有答案都已定义。

编辑：要在下面的评论中回答您的问题，首先我想我会将其绑定到按钮onclick事件，但要保持验证在这种情况下很方便（当一些时候如果问题没有得到回答，请注意用户注意事项。我认为表格onsubmit会更好。我仍然会阻止默认行为，因此表单并未真正提交，但请记住，如果有人将js禁用，它将提交表单以便牢记这一点。因此，下一个按钮是提交类型，它将尝试提交表单，在onsubmit事件处理程序中我阻止表单提交并检查答案。

＆＃13;

＆＃13;

$(document).ready(function() {
    $('#questions').on('submit', function(e) {
      e.preventDefault(); // Prevent form submition; 
      
      var userAnswers = [
        $('input[name=questionOne]:checked', '#questions').val(),
        $('input[name=questionTwo]:checked', '#questions').val(),
        $('input[name=questionThree]:checked', '#questions').val()
      ];
      
      //Array that contains right answers, indexes must match userAnswers array.
      var rightAnswers = [2, 6, 8];
      
      //Check if all answers are defined
      for(var i = 0; i < userAnswers.length; i++){
        if(typeof userAnswers[i] === 'undefined'){
          return;
        }
      }
      
      //Check if all answers are rightAnswers
      for(var i = 0; i < userAnswers.length; i++){
        if(userAnswers[i] != rightAnswers[i]){
          return console.log('Found wrong answer!');
        }
      }
      
      console.log('All answers are correct.');
    });
});
