Modal Bootstrap on Modal by JS

Question

Good afternoon,

I saw several examples on the internet of a modal opening over another modal with the bootstrap, but none of them using javascript. There is no way to open a modal over the other with bootstrap using javascript?

Answer 1

Let’s get right to the answer:

Using setTimeout, for the .modal-backdrop is not created when the event show.bs.modal is triggered.

$(document).ready(function () {
    $('#abrir').click(function () {
        $('#myModal').modal({
            show: true
        })
    });
        $(document).on('show.bs.modal', '.modal', function (event) {
            var zIndex = 1040 + (10 * $('.modal:visible').length);
            $(this).css('z-index', zIndex);
            setTimeout(function() {
                $('.modal-backdrop').not('.modal-stack').css('z-index', zIndex - 1).addClass('modal-stack');
            }, 0);
        });
});

Answer 2

I went through the same problem, you must keep information of how many modals are open, if a new one is open it must have a z-index higher than what is already, to always appear in front, for that the events shows and Hidden of the modal are treated. follows the example of the code:

$('.modal').on('hidden.bs.modal', function( event ) {
            $(this).removeClass( 'fv-modal-stack' );
            $('body').data( 'fv_open_modals', $('body').data( 'fv_open_modals' ) - 1 );
            });


$( '.modal' ).on( 'shown.bs.modal', function ( event ) {

               // keep track of the number of open modals

               if ( typeof( $('body').data( 'fv_open_modals' ) ) == 'undefined' )
               {
                 $('body').data( 'fv_open_modals', 0 );
               }


               // if the z-index of this modal has been set, ignore.

            if ( $(this).hasClass( 'fv-modal-stack' ) )
                    {
                    return;
                    }

            $(this).addClass( 'fv-modal-stack' );

            $('body').data( 'fv_open_modals', $('body').data( 'fv_open_modals' ) + 1 );

            $(this).css('z-index', 1040 + (10 * $('body').data( 'fv_open_modals' )));

            $( '.modal-backdrop' ).not( '.fv-modal-stack' )
                    .css( 'z-index', 1039 + (10 * $('body').data( 'fv_open_modals' )));


            $( '.modal-backdrop' ).not( 'fv-modal-stack' )
                    .addClass( 'fv-modal-stack' ); 

             });


    });

Answer 3

It is possible to use without javascript, just put a button inside an open modal to call the other modal.

If you want to use javascript to call Modal, use the following code:

$('.btn.chamar-modal-a').on('click',function(){
    $("#modalA").modal('show');
}

OBS: Pay attention to the overlap of Modal, in the code, puts Modal A after Modal B, ie Modal A on top of Modal B.

Answer 4

Yes, you can open a modal over another one using Javascript. See this example:

HTML:

<a data-toggle="modal" href="#myModal" class="btn btn-primary">Launch modal</a>

<div class="modal" id="myModal">
    <div class="modal-dialog">
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
          <h4 class="modal-title">Modal title</h4>
        </div><div class="container"></div>
        <div class="modal-body">
          Content for the dialog / modal goes here.
          <br>
          <br>
          <br>
          <br>
          <br>
          <a data-toggle="modal" href="#myModal2" class="btn btn-primary">Launch modal</a>
        </div>
        <div class="modal-footer">
          <a href="#" data-dismiss="modal" class="btn">Close</a>
          <a href="#" class="btn btn-primary">Save changes</a>
        </div>
      </div>
    </div>
</div>
<div class="modal" id="myModal2" data-backdrop="static">
    <div class="modal-dialog">
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
          <h4 class="modal-title">Second Modal title</h4>
        </div><div class="container"></div>
        <div class="modal-body">
          Content for the dialog / modal goes here.
        </div>
        <div class="modal-footer">
          <a href="#" data-dismiss="modal" class="btn">Close</a>
          <a href="#" class="btn btn-primary">Save changes</a>
        </div>
     </div>
   </div>

Javascript:

$('#openBtn').click(function(){
    $('#myModal').modal({show:true})
});
