我做了一个多步骤的形式与步骤验证所需的我应用验证这个多步骤的形式，但现在我想删除验证所需的从没有4步骤，因为在没有4步骤，我需要添加一些输入字段和前三个步骤，我添加一些电台输入请检查我的代码。

jQuery

$(document).ready(function() {
  var currentStep = 0;
  var steps = $('.step');
  
  // Show the first step
  $(steps[currentStep]).addClass('activee'); 
  // Next button click event
  $('.next').click(function() {  
    if (validateStep(currentStep)) {
      $(steps[currentStep]).removeClass('activee');
      currentStep++;
      $(steps[currentStep]).addClass('activee');
    }
      
  });
  
  // Previous button click event
  $('.prev').click(function() {
    $(steps[currentStep]).removeClass('activee');
    currentStep--;
    $(steps[currentStep]).addClass('activee');
  });
  
  // Submit button click event
  $('.submit').click(function() {
    if (validateStep(currentStep)) {
      alert('Form submitted successfully!');
    }
  });
    
      // Function to validate each step
  function validateStep(step) {
    var checkboxes = $(steps[step]).find('input[type="radio"]'); 
    var checked = checkboxes.is(':focus');
    
    if (!focus) {
      alert('Please select at least one option');
      return false;
    }
    
    return true;
  }
});
