: Parent.dataLayer.push when iFrame is on https I want to send information from an iFrame into the parent page using a parent.dataLayer.push, see: https://stackoverflow.com/questions/22382182/google-tag-manager-datalayer-within-iframes/

@Vandalay111

Because the two frames are using different "schemes" (aka "protocols"), browsers will consider them to be on different " origins". This means they aren't allowed to communicate with each other using normal means (i.e. direct access to each others' objects).

The only way around this is to use some form of "cross-origin communication". If you're only targeting modern browsers (i.e. IE8+), you can use the post-message APIs:
developer.mozilla.org/en-US/docs/Web/API/Window/postMessage
