I have a page with several iframes, each with its respective htmls. It would be great to dispatch/broadcast a custom event/message from an specific html page that could be handled by all other pages. Thanks for any tip.
Such functionality is possible with Webix Jet micro framework that uses a global event bus to connect views - you trigger the event in one view (described in one js file), and listen to it in any other view (other js file). But perhaps, you will have to use Webix iframe component for your iframes.
You can study the framework on Gitbook (events are described in the third chapter).
