在重新加载的 iframe 中使用 postMessage 不起作用

Question

I have iframe with simple form (provided by third-party vendor). The content of iframe reloads after form is submitted with confirmation page. On that page I asked provider to add this script:

<script type="text/javascript">
    window.setTimeout(function(){
        window.parent.postMessage('mailing_list_confirmation','http://originURL.com/');
    },100) </script>

I the top window I have:

<script>
    jQuery(function($) {
    $(window).on('mailing_list_confirmation',function(){
          console.log("iframe_message");
       });
    });
</script>

Nothing complicated. I tried also with plain JS. I tried this on my localhost (2 different domains) and it was working well. The difference was that the iframe was originally loaded. In this case the iframe content is new page. Is there any other reason why this might not work?

Answer 1

That should work, check the domain your posting to is what you think it is and not www.originaldomain.com.
