Get callback on parent page when embedded Youform has been loaded

When you embed a Youform on your page and it has been loaded then we trigger an event named youformLoaded to the parent page.

You can listen to that event to do things like show a message, record analytics, etc.

Here is a sample code for how to listen to that message and then perform an action on your page:

<script>
    window.addEventListener('message', function(event) {
        if (event.data && event.data == 'youformLoaded') {
            console.log('Youform embed loaded');
        }
    });
</script>
