Twitter bootstrap – Bootstrap 4 with remote Modal

I can’t make the Modal work in the remote mode with the new Twitter Bootstrap release : Bootstrap 4 alpha. It works perfectly fine with Bootstrap 3. With bootstrap 4 I am getting the popup window, but the model body is not getting loaded. There is no remote call being made to myRemoteURL.do to load the model body.

Code:

<button type="button" data-toggle="modal" data-remote="myRemoteURL.do" data-target="#myModel">Open Model</button>

<!-- Model -->
<div class="modal fade" id="myModel" tabindex="-1"
    role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal"
                    aria-label="Close">
                    <span aria-hidden="true">&times;</span>
                </button>
                <h3 class="modal-title" id="myModalLabel">Model Title</h3>
            </div>
            <div class="modal-body">
                <p>
                    <img alt="loading" src="resources/img/ajax-loader.gif">
                </p>
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                <button type="button" class="btn btn-primary">Submit</button>
            </div>
        </div>
    </div>
</div>

    Found the problem: They have removed the remote option in bootstrap 4

    remote : This option is deprecated since v3.3.0 and will be removed in v4. We recommend instead using client-side templating or a data binding framework, or calling jQuery.load yourself.

    I used JQuery to implement this removed feature.

    $('body').on('click', '[data-toggle="modal"]', function(){
        $($(this).data("target")+' .modal-body').load($(this).data("remote"));
    });

    According to official documentation, we can do the follow(https://getbootstrap.com/docs/4.1/components/modal):

    $('#exampleModal').on('show.bs.modal', function (event) {
    var button = $(event.relatedTarget) // Button that triggered the modal
    var recipient = button.data('whatever') // Extract info from data-* attributes
    // If necessary, you could initiate an AJAX request here (and then do the updating in a callback).
    // Update the modal's content. We'll use jQuery here, but you could use a data binding library or other methods instead.
    var modal = $(this)
    modal.find('.modal-title').text('New message to ' + recipient)
    modal.find('.modal-body input').val(recipient)
})

    So, I believe this is the best approach (works for BS 5 too):

    <!-- Button trigger modal -->
<a data-bs-toggle="modal" data-bs-target="#modal_frame" href="/otherpage/goes-here">link</a>

<!-- Modal -->
<div class="modal fade" id="modal_frame" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <!-- Completes the modal component here -->
</div>

<script>
  $('#modal_frame').on('show.bs.modal', function (e) {
    $(this).find('.modal-body').load(e.relatedTarget.href);
  });
</script>

    e.relatedTarget is the anchor() that triggers the modal.

    As some of the other answers and Bootstrap docs indicate, Bootstrap 4 requires handling the show.bs.modal event to load content into the modal. This can be used to either load content from an HTML string, or from a remote url. Here’s a working example…

    $('#theModal').on('show.bs.modal', function (e) {

    var button = $(e.relatedTarget);
    var modal = $(this);

    // load content from HTML string
    //modal.find('.modal-body').html("Nice modal body baby...");

    // or, load content from value of data-remote url
    modal.find('.modal-body').load(button.data("remote"));

});

    Another option is to open the modal once data is returned from an Ajax call…

      $.ajax({
       url: "http://someapiurl",
       dataType: 'json',
       success: function(res) {

           // get the ajax response data
           var data = res.body;
           // update modal content
           $('.modal-body').text(data.someval);
           // show modal
           $('#myModal').modal('show');

       },
       error:function(request, status, error) {
           console.log("ajax call went wrong:" + request.responseText);
       }
  });

    If you use the Jquery slim version (as in all the Bootstrap 4 docs and examples) the load function will fail

    You need to use the full version of Jquery

    In Asp.NET MVC, this works for me

    html

    <a href="#" onclick="Edit(1)">Edit item</a>
<div class="modal" id="modalPartialView" />

    jquery

    <script type="text/javascript">
        function Edit(id)
        {
            $.ajax({
                url: "@Url.Action("ActionName","ControllerName")",
                type: 'GET',
                cache: false,
                data: {id: id},
            }).done(function(result){
                $('#modalPartialView').html(result)
                $('#modalPartialView').modal('show') //part of bootstrap.min.js
            });
        }
<script>

    Action

    public PartialViewResult ActionName(int id)
{
   // var model = ...
   return PartialView("_Modal", model);
}

    This process is loading the current dynamic. data remote = “remoteContent.html”

    <!-- Link trigger modal -->
<a href="javascript:void(0);" data-remote="remoteContent.html" data-toggle="modal" data-target="#myModal" data-remote="true" class="btn btn-default">
    Launch Modal
</a>
This trick :  data-remote="remoteContent.html"
<!-- Default bootstrap modal example -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
