How to hide the body scroll bar when showing scroll is in modal dialog?

When I open modal dialog, body has overflow:auto. But when modal dialog has its own scroll, we see two scrolls - active and unactive. How can I retain only one, active scroll? Now situation like this

html {
  overflow-y: scroll;
  overflow-x: auto;
}

.modal-open .modal {
    overflow-x: hidden;
    overflow-y: auto;
}

It's simple. Just add the body tag overflow:hidden; when the popup is shown.

The snippet bellow just use bootstrap modal. If you will lookup the result html when the popup is shown, you can see it.

p {
  margin-top:350px !important;
}

  <!-- Trigger the modal with a button -->
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>
  <p>Text</p>
  <p>Text</p>
  <p>Text</p>
  <p>Text</p>
  <p>Text</p>
  <p>Text</p>
<!-- Modal -->
<div id="myModal" class="modal fade" role="dialog">
  <div class="modal-dialog">

    <!-- Modal content-->
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal">&times;</button>
        <h4 class="modal-title">Modal Header</h4>
      </div>
      <div class="modal-body">
        <p>Some text in the modal.</p>
        <p>Some text in the modal.</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>

  </div>
</div>
  
  <script src="https://code.jquery.com/jquery-2.1.4.min.js"></script>
