Bootstrap 3 - How to load content in modal body via AJAX?

As you can see here, I have a button that launches a modal. Setting an href url for the button this url is automatically loaded into modal by Bootstrap 3. The fact is this page is loaded into modal root (as said in the bootstrap 3 documentation for modals usage). I want to load it into the modal-body instead.

Is there a way to do it via attributes (not javascript)? Or what is the most automatic way to do it?

P.S. I remember in Bootstrap 2 the content was loaded in the body, not the root.

This is actually super simple with just a little bit of added javascript. The link's href is used as the ajax content source. Note that for Bootstrap 3.* we set data-remote="false" to disable the deprecated Bootstrap load function.

JavaScript:

// Fill modal with content from link href
$("#myModal").on("show.bs.modal", function(e) {
    var link = $(e.relatedTarget);
    $(this).find(".modal-body").load(link.attr("href"));
});

Html (based on the official example):

<!-- Link trigger modal -->
<a href="remoteContent.html" data-remote="false" data-toggle="modal" data-target="#myModal" class="btn btn-default">
    Launch Modal
</a>

<!-- 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>
</div>

It looks like the only way is to provide the whole modal structure with your ajax response.

As you can check from the bootstrap source code, the load function is binded to the root element.

In case you can't modify the ajax response, a simple workaround could be an explicit call of the $(..).modal(..) plugin on your body element, even though it will probably break the show/hide functions of the root element.

I guess you're searching for this custom function. It takes a data-toggle attribute and creates dynamically the necessary div to place the remote content. Just place the data-toggle="ajaxModal" on any link you want to load via AJAX.

The JS part:

$('[data-toggle="ajaxModal"]').on('click',
              function(e) {
                $('#ajaxModal').remove();
                e.preventDefault();
                var $this = $(this)
                  , $remote = $this.data('remote') || $this.attr('href')
                  , $modal = $('<div class="modal" id="ajaxModal"><div class="modal-body"></div></div>');
                $('body').append($modal);
                $modal.modal({backdrop: 'static', keyboard: false});
                $modal.load($remote);
              }
            );

Finally, in the remote content, you need to put the entire structure to work.

<div class="modal-dialog">
    <div class="modal-content">
        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal">&times;</button>
            <h4 class="modal-title"></h4>
        </div>
        <div class="modal-body">
        </div>
        <div class="modal-footer">
            <a href="#" class="btn btn-white" data-dismiss="modal">Close</a>
            <a href="#" class="btn btn-primary">Button</a>
            <a href="#" class="btn btn-primary">Another button...</a>
        </div>
    </div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
