Bootstrap modal inside modal background scrolling – Twitter bootstrap

I have a modal with a long content and a button that opens another modal. When I close the inner modal, the outer modal is stuck. It cannot be scrolled, rather the background begins to scroll.

I have found a few questions relating to modal and scrolling like bootstrap modal inside a modal and Prevent BODY from scrolling when a modal is opened, but my issue doesn’t seem to be replicated here.

I have forked a fiddle from Bootstrap 3: prevent modal inside modal to trigger (hidden.bs.modal) every time to demonstate this issue. After clicking on the Cancel from the second modal, the first modal is stuck.

code:

$('#btnUploadCancel').click(function() {
  $('#uploadImage').modal('toggle');
});

<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">Open demo modal</button>
<p>
  Lorem ipsum .... long content

<div class="modal" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="false">
  <div class="modal-dialog modal-sm">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
        <h4 class="modal-title" id="myModalLabel">Demo Modal</h4>
      </div>

          <a href="#" data-toggle="modal" data-target="#uploadImage" class="btn btn-primary">Upload image</a>
        </p>
        Lorem ipsum ... long content
        <p>

    Edit your javascript to leave first modal open like this – 

        $('#btnUploadCancel').click(function () {
    $('#uploadImage').modal('toggle');

    $('body').addClass('modal-open');
});

    $('.modal').on('show.bs.modal', function (event) {
        var idx = $('.modal:visible').length;
        $(this).css('z-index', 1040 + (10 * idx));
    });
    $('.modal').on('shown.bs.modal', function (event) {
        var idx = ($('.modal:visible').length) - 1; // raise backdrop after animation.
        $('.modal-backdrop').not('.stacked').css('z-index', 1039 + (10 * idx));
        $('.modal-backdrop').not('.stacked').addClass('stacked'); 
    });
   $('.modal').on('hide.bs.modal', function (event) { 
        var modal_length =  $('.modal:visible').length;
        if (modal_length>1)
        {
            $("body").css("overflow","hidden");
            $('.modal:visible').css("overflow-y","auto");
        }
    });

    Bootstrap modal when shown adds a new modal-open class to your body element. And when being closed, it removes the modal-open class.

    So you only need to re-apply that class to your body element when closing the child modal. Here’s the thing:

    Add a new custom css class for the modals inside your parent modal.

    in my case, I use .child-modal,

    /* when using a modal within a modal, add this class on the child modal */
$(document).find('.child-modal').on('hidden.bs.modal', function () {
    console.log('hiding child modal');
    $('body').addClass('modal-open');
});

    html

    <div class="modal fade" tabindex="-1" role="dialog">
     ...
     <a href="#" data-toggle="modal" data-target="#other_modal" title="Help">
       Open the other modal
     </a>
     ...
</div>
<div class="modal fade child-modal" id="other_modal" tabindex="-1" role="dialog">
   ... other codes here ...
</div>

    See working snippet below: 

    $('#btnUploadCancel').click(function() {
  $('#uploadImage').modal('toggle');
});


$(document).find('.child-modal').on('hidden.bs.modal', function () {
    console.log('hiding child modal');
    $('body').addClass('modal-open');
});
