Open an iFramed Marketo Form's Follow Up Page in the parent page

In some cases, you may want an iframed Marketo form to open in the parent page.

FORMS 1.0
Add the following script to the src iframed page within a custom HTML block.

<script type="text/javascript" src="/js/public/jquery-latest.min.js"></script>
<script type="text/javascript">
     // set no conflict mode for jquery
   var $jQ = jQuery.noConflict();

   $jQ(document).ready(function(){
       // all form submits will open in a new window
     $jQ('.lpeRegForm').attr('target','_top');
   });
</script>

FORMS 2.0

<script >

MktoForms2.whenReady(function (form) {

    var form = MktoForms2.getForm(FORM_ID_HERE);

    form.onSuccess(function (values, followUpUrl)

    { window.top.location.href = followUpUrl; return false;

    });

});

</script>

To figure out what the form id is, the easiest way is to look at the embed code. It is the 4 digit number on the second line.
