Reuse JavaScript script for multiple html forms on same page

Question

I have a page that has multiple forms that i need to use the same JavaScript code on. The JavaScript code adds more input fields to the form. The script works fine but adds input fields to all forms. I need it to only add fields to the current form being filled out. So far I haven't had any luck.

Here is what one of the forms looks like:

<form>
<div class="price-group">
  <div class="price-fields">
  <label>Multiple <a class="add-field" href="#"> Add Field</a></label>
    <br><input  maxlength="7" type="text" name="prices[]" />
  </div><!--end form-group price-fields-->
</div><!--end price-group-->
</form>

Here is my JavaScript:

$(document).ready(function($){
     $('.price-group .add-field').click(function(e){
          e.preventDefault();
          var n = $('.price-fields').length;
          $('.price-group').append('<div class=" price-fields"><input  maxlength="7" type="text" name="prices[]"  /><a class="remove-field pull-right" href="#">Remove</a></div><!--end form-group-->');
     });
     $('.price-group').on('click', '.remove-field', function(){
          $(this).parent().fadeOut("slow", function() {
              $(this).remove();
          });
          return false;
     });
});

You can use jQuery closest to find the closest .price-fields to the clicked <a> tag:

$(document).ready(function($){
     $('.price-group .add-field').click(function(e){
          e.preventDefault();
          var n = $('.price-fields').length;
          $(this).closest('.price-group').append('<div class=" price-fields"><input  maxlength="7" type="text" name="prices[]"  /><a class="remove-field pull-right" href="#">Remove</a></div><!--end form-group-->');
     });
     $('.price-group').on('click', '.remove-field', function(){
          $(this).parent().fadeOut("slow", function() {
              $(this).remove();
          });
          return false;
     });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<div class="price-group">
  <div class="price-fields">
  <label>Multiple <a class="add-field" href="#"> Add Field</a></label>
    <br><input  maxlength="7" type="text" name="prices[]" />
  </div><!--end form-group price-fields-->
</div><!--end price-group-->
</form>
