Receive iframe messages without using old v1 library

I just want to embed an iframe and listen for messages myself ("onResize", "onSubmit", "onSuccess", "onCancel", "onError", ...)

I don't want to pull this: It contains old code I don't use.

How come if I don't use this library the embedded iframe doesn't post messages to the parent?

Thank you!

I was doing that but still it wasn't working.

After re-reading the original library, when embedding the iframe, one must specify the URL of the container like:

<iframe src="<url-of-form>#<url-of-this-page>"/>

Thanks Vaishnavi :)

Hello Mike

You can certainly listen to the messages without the library. 

Please check this sample code snippet that listens to the messages sent from the iframe.


var eventMethod = window.addEventListener ? "addEventListener" : "attachEvent";
var eventer = window[eventMethod];
var messageEvent = eventMethod == "attachEvent" ? "onmessage" : "message";

// Listen to message from child window
eventer(messageEvent,function(e) {
  // will be json string
  var messObj = JSON.parse(;
    // onload callback
  // |||ly check for

  // messObj.resize
  // messObj.onSubmit
  // messObj.success
  // messObj.cancel
