PostMessage issues in SL360

Hi! 

I have to link an embedded interactive video to SL. For this I want to use the PostMessage() method from iframe to parent. With the little experience I have in Javascript I first had to find out the basics. Now I'm able to get the connection working in html with two different domains, send a message and check if the condition of the message is right before executing anything.

For this I used the following javascript code. 

//script used in the body of the iframe:

<script>
window.onload = function(e){
parent.postMessage('test', '*http://www.url.com');
};
</script>

// *i've changed the url for this message
//script used in the body of the HTML parent:

<script>
window.addEventListener('message',function(e){
if(e.data == 'test'){
alert('true');
console.log('message received...');
console.log(e);
}
});
</script>


//script used in Storyline onClick Execute Javascript trigger:

window.addEventListener('message',function(e){
if(e.data == 'test'){
alert('true');
console.log('message received...');
console.log(e);
}
});

In SL I've inserted the same iframe. I've created a simple button to trigger the script. I've published to web and uploaded it to the same domain as the parent HTML I mentioned before. Unfortunately it doesn't work. Does anyone know what I'm doing wrong? Can anyone help me? 

//I'm getting this message in the developer console while testing in Chrome

Hello,

I have attached a couple of files for you to take a look at.

On timeline start there is a javascript function that listens for incoming messages. It will alert true if the message received is equal to: test

The webobject points to an html file on my server. I named it child. It has a javascript window.onload function that calls parent.postMessage.
