Using bootstrap 3.0 modals to load dynamic, remote content within an iframe

Question

I have tried several of the suggestions posted here on other questions and on stackexchange, and nothing is working to my satisfaction.

I am trying to load dynamic

Answer 1

Why neither data-remote or href work on remote sites like youtube

Twitter bootstrap's modal uses AJAX to load remote content via data-remote/href. AJAX is constrained by the same origin policy so accessing a site with a different origin, like youtube, will produce this error:

No 'Access-Control-Allow-Origin' header is present on the requested resource

So neither data-remote or href will do what you want.

JSON: If you were getting json data then you could potentially use JSONP. But since you need html, not json, from sites like youtube we need another approach:

Solution using <iFrame>

An <iframe> will work for youtube and many other remote sites (even this solition doesn't work for all sites as some, like Facebook, explicitly block iframes by setting X-Frame-Options' to 'DENY') .

One way to use an iframe for dynamic content is to:

1) add an empty iframe inside your modal's body:

<div class="modal-body">
    <iframe frameborder="0"></iframe>
</div>

2) add some jquery that is triggered when the modal dialog button is clicked. The following code expects a link destination in a data-src attribute and for the button to have a class modalButton. And optionally you can specify data-width and data-height- otherwise they default to 400 and 300 respectively (of course you can easily change those).

The attributes are then set on the <iframe> which causes the iframe to load the specified page.

$('a.modalButton').on('click', function(e) {
    var src = $(this).attr('data-src');
    var height = $(this).attr('data-height') || 300;
    var width = $(this).attr('data-width') || 400;

    $("#myModal iframe").attr({'src':src,
                               'height': height,
                               'width': width});
});

3) add the class and attributes to the modal dialog's anchor tag:

<a class="modalButton" data-toggle="modal" data-src="http://www.youtube.com/embed/Oc8sWN_jNF4?rel=0&wmode=transparent&fs=0" data-height=320 data-width=450 data-target="#myModal">Click me</a>

Demo Fiddle using youtube

Answer 2

if you need show a preformatted web page, need something like this

$('#btn').click(function() {
    $.ajax({
        url: 'url-src/dialog.html',
        dataType: 'json',
        type: 'POST',
        success: function(data) {
            if (data.check) {
                var $modal = $(data.dialog);
                $('body').append($modal);
                $modal.filter('.modal').modal();
            } else {
                alert(data.dialog);
            }

        }
    });

});

html of the dialog.html

<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-hidden="true">×</button>
            <h3>Dialog</h3>
        </div>
        <div class="modal-body">
            <form role="form"  class="form-horizontal">
                <div class="form-group">
                    <label class="col-sm-3 control-label" for="mutual">Example: </label>
                    <div class="col-sm-6">
                        <input type="text" id="example-form" value="" class="form-control">
                    </div>
                </div>
            </form>
        </div>
        <div class="modal-footer">
            <button id="edit-form"  data-id-mutual="" class="btn btn-primary">Save</button>
            <button class="btn btn-danger" data-dismiss="modal" aria-hidden="true">Cancel</button>
        </div>
    </div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
</div><!-- /.modal -->

this html have a form example, you have to add a html with video inside.

Answer 3

function javascript_function(item_code)
{
var d = new Date();
var url_to_zoom='http://localhost.com/application/page.php?id=2&item_code='+item_code+'&reqdate='+d.getTime();

$('#modal_box').modal({keyboard:true,backdrop:true,show:true,remote:url_to_zoom});
}

Answer 4

you can try this bootstrap helper to dialogs

it has support for ajax request, iframes, common dialogs, confirm and prompt!

you can use it as:

eModal.iframe('http://someUrl.com', 'This is a tile for iframe', callbackIfNeeded);

eModal.alert('The message', 'This title');

eModal.ajax('/mypage.html', 'This is a ajax', callbackIfNeeded);

eModal.confirm('the question', 'The title', theMandatoryCallback);

eModal.prompt('Form question', 'This is a ajax', theMandatoryCallback);

this provide a loading progress while loading the iframe!

No html required.

You can use a object literal as parameter to extra options.

Check the site form more details.

best,

Answer 5

Probably an old post, I had a similar problem a time ago, i wanted to press a link, which would pass the href of a text file (or any other file) to an iframe inside a modal window, i solved like this:

function loadiframe(htmlHref) //load iframe
{
document.getElementById('targetiframe').src = htmlHref;
}


function unloadiframe() //just for the kicks of it
{
var frame = document.getElementById("targetiframe"),
frameHTML = frame.contentDocument || frame.contentWindow.document;
frameHTML.removeChild(frameDoc.documentElement);	
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap-theme.min.css" rel="stylesheet"/>

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css" rel="stylesheet"/>

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script>


<a class=" btn btn-danger" onClick="loadiframe('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css')" data-toggle="modal" data-target="#myModal">LINK</a><!--link to iframe-->




<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" style="border:hidden">
        <button type="button" class="close" onClick="unloadiframe()" data-dismiss="modal" aria-label="Close"><span aria-   hidden="true">&times;</span></button>
      </div>
      
      <div class="modal-body" style="padding-top:10px; padding-left:5px; padding-right:0px; padding-bottom:0px;">
        
      <iframe src="" frameborder="0" id="targetiframe" style=" height:500px; width:100%;" name="targetframe" allowtransparency="true"></iframe> <!-- target iframe -->
        
      </div> <!--modal-body-->
      
      <div class="modal-footer" style="margin-top:0px;">
        <button type="button" class="btn btn-default pull-right" data-dismiss="modal" onClick="unloadiframe()">close</button>
      </div>
      
    </div>
  </div>
</div>

So in this case you have only one modal, one iframe, which you load and unload.
