I created a HTML web resource on a form. This HTML generates an iFrame dynamically. It also needs to listen to requests coming from the child iFrame and blink/stop blinking the browser's tab.
Our dynamics CRM is over HTTP and the iFrame is over HTTPS.
This is the HTML:
Inside the iFrame, which we do not have access to as it is in another domain, the postMessage API is used to send data to the parent HTML like so:
window.parent.postMessage(JSON.stringify({active: 1}), "http://path/to/our/org"); // our CRM is over HTTP
but the debugger inside messageHandler will not be hit.
The checkbox restrict cross-frame scripting is unmarked.
We are using Dynamics CRM v8.1 on-premise if that matters.
