load external URL into modal jquery ui dialog

why doesn't this display ibm.com into a 400x500px modal? The section appears to be correct, but it doesn't cause the popup modal to appear.

var page = "http://somurl.com/asom.php.aspx";

var $dialog = $('<div></div>')
               .html('<iframe style="border: 0px; " src="' + page + '" width="100%" height="100%"></iframe>')
               .dialog({
                   autoOpen: false,
                   modal: true,
                   height: 625,
                   width: 500,
                   title: "Some title"
               });
$dialog.dialog('open');

Use this inside a function. This is great if you really want to load an external URL as an IFRAME. Also make sure that in you custom jqueryUI you have the dialog.


EDIT: This answer might be outdated if you're using a recent version of jQueryUI.

For an anchor to trigger the dialog -

<a href="http://ibm.com" class="example">

Here's the script -

$('a.example').click(function(){   //bind handlers
   var url = $(this).attr('href');
   showDialog(url);

   return false;
});

$("#targetDiv").dialog({  //create dialog, but keep it closed
   autoOpen: false,
   height: 300,
   width: 350,
   modal: true
});

function showDialog(url){  //load content and open dialog
    $("#targetDiv").load(url);
    $("#targetDiv").dialog("open");         
}

The following will work out of the box on any site:

<script src="//code.jquery.com/jquery-1.11.1.min.js"></script>
<script src="//code.jquery.com/ui/1.11.1/jquery-ui.min.js"></script>
 
    <div class="dialogBox" style="border:1px solid gray;">
        <a href="/" class="exampleLink">Test</a>
        <!-- TODO: Change above href -->
        <!-- NOTE: Must be a local url, not cross domain -->
    </div>
    
    <script type="text/javascript">
         

        var $modalDialog = $('<div/>', { 
          'class': 'exampleModal', 
          'id': 'exampleModal1' 
        })
        .appendTo('body')
        .dialog({
            resizable: false,
            autoOpen: false,
            height: 300,
            width: 350,
            show: 'fold',
            buttons: {
                "Close": function () {
                    $modalDialog.dialog("close");
                }
            },
            modal: true
        });

        $(function () {
            $('a.exampleLink').on('click', function (e) {
                e.preventDefault();
                // TODO: Undo comments, below
                //var url = $('a.exampleLink:first').attr('href');
                //$modalDialog.load(url);
                $modalDialog.dialog("open");
            });
        });

    </script>

if you are using **Bootstrap** this is solution, 

$(document).ready(function(e) {
    $('.bootpopup').click(function(){
  var frametarget = $(this).attr('href');
  targetmodal = '#myModal'; 
        $('#modeliframe').attr("src", frametarget );   
});
});

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">

        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

Modals always load the content into an element on the page, which more often than not is a div. Think of this div as the iframe equivalent when it comes to jQuery UI Dialogs. Now it depends on your requirements whether you want static content that resides within the page or you want to fetch the content from some other location. You may use this code and see if it works for you:

    <p>First open a modal <a href="http://ibm.com" class="example"> dialog</a></p>
    <div id="dialog"></div>
</body>

<!--jQuery-->
<script src="http://code.jquery.com/jquery-latest.pack.js"></script>

<script type="text/javascript">

$(function(){
//modal window start
$(".example").unbind('click');
$(".example").bind('click',function(){
    showDialog();
    var titletext=$(this).attr("title");
    var openpage=$(this).attr("href");
    $("#dialog").dialog( "option", "title", titletext );
    $("#dialog").dialog( "option", "resizable", false );
    $("#dialog").dialog( "option", "buttons", { 
        "Close": function() { 
            $(this).dialog("close");
            $(this).dialog("destroy");
        } 
    });
    $("#dialog").load(openpage);
    return false;
});

//modal window end

//Modal Window Initiation start

function showDialog(){
    $("#dialog").dialog({
        height: 400,
        width: 500,
        modal: true 
    }
</script>

There are, however, a few things which you should keep in mind. You will not be able to load remote URL's on your local system, you need to upload to a server if you want to load remote URL. Even then, you may only load URL's which belong to the same domain; e.g. if you upload this file to 'www.example.com' you may only access files hosted on 'www.example.com'. For loading external links this might help. All this information you will find in the link as suggested by @Robin.
