jquery multi step form with validation and next previous navigation

Creating a multi-step form with validation and next/previous navigation using jQuery involves the following steps:

HTML: Create an HTML form with multiple sections, each containing the form fields for a single step. For example:

  

    
    
    Next
  
  

    
    
    Previous
    Next
  
  

    
    
    Previous
    Submit
  

CSS: Use CSS to hide all but the first step of the form, and to style the next/previous buttons as needed.

.step-section {
  display: none;
}
#step-1 {
  display: block;
}
.next-button {
  float: right;
}
.prev-button {
  float: left;
}

JavaScript: Use jQuery to handle the next/previous button clicks, and to validate the form fields for each step. For example:

$(document).ready(function() {
  var current_step = 1;
  var steps = $('.step-section').length;

  $('.next-button').click(function() {
    if (validateStep(current_step)) {
      $('#step-' + current_step).hide();
      current_step++;
      $('#step-' + current_step).show();
    }
  });

  $('.prev-button').click(function() {
    $('#step-' + current_step).hide();
    current_step--;
    $('#step-' + current_step).show();
  });

  function validateStep(step) {
    var is_valid = true;
    $('#step-' + step + ' input').each(function() {
      if ($(this).val() == '') {
        is_valid = false;
        $(this).addClass('error');
      } else {
        $(this).removeClass('error');
      }
    });
    return is_valid;
  }

  $('#multi-step-form').submit(function() {
    if (validateStep(current_step)) {
      return true;
    } else {
      return false;
    }
  });
});

In the above code, we first set the current_step variable to 1, and the steps variable to the total number of steps in the form.

We then use jQuery to handle the click events of the next/previous buttons. When the user clicks the next button, we first validate the fields in the current step using the validateStep() function. If the fields are valid, we hide the current step section, increment the current_step variable, and show the next step section. If the user clicks the previous button, we hide the current step section, decrement the current_step variable, and show the previous step section.

The validateStep() function checks the form fields for the given step and adds the error class to any fields that are empty.
