javascript - Loading iframe in modal, .modal-content is replaced -

i have following html:

<a href="http://domainx.com/" class="btn btn-primary" data-toggle="modal" data-target="#mymodal">linky</a>  <!-- modal --> <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">&times;</button>             </div>             <div class="modal-body">                 <h4 class="modal-title" id="mymodallabel">modal title</h4>                 <iframe src="http://domainy.com/" width="100%" height="380" frameborder="0"                         allowtransparency="true"></iframe>             </div>         </div>         <!-- /.modal-content -->     </div>     <!-- /.modal-dialog --> </div> <!-- /.modal --> 

when change modal iframe src following js, content of .modal-content overwritten html loaded href in question on button toggled modal.

$('[data-target="#mymodal"]').on('click', function (e) {     e.preventdefault();      var _linky = $(this).attr('href');     var _target = $(this).data('target');      if (_target.length > 0) {         _target.find('iframe').attr('src', 'about:blank');          var _isremote = false;         if (_linky.indexof('http') > -1) {             _isremote = true;         }          if (!_isremote) {             if (_linky.indexof('?') > -1) {                 _linky += '&tmpl=component';             } else {                 _linky += '?tmpl=component';             }         }          _target.find('iframe').attr('src', _linky).load(function() {             _target.modal('show');         });     } });  $('body').on('hidden.bs.modal', '.modal', function () {     $(this).removedata('bs.modal'); }); 

how can prevent bootstrap replacing in .modal-content?

_target simple string value representing elements id - not jquery object.
