Notification from iFrame? (MMM-Glance and ...?)

mmmmh

I have a web page with some button elements. The web page is shown via MMM-iFrameReload. How can I generate a notification from that web page? I would like to use MMM-Glance to temporarily hide another module.

@mmmmh far as I know, the page in the iframe does not KNOW its in a frame, vs being in a web browser someplace else… and is boxed in a container that it cannot communicate thru (this would be a HUGE security exposure to let a framed page get to outside the frame)

mmmmh

@sdetweil Thanks for the feedback. I thought so. I guess I’ll cook something up with MMM-Remote-Control.

OK, for posterity, here’s what I did.

I used MMM-Remote-Control and created a button element that calls a function that issues a get request. Interestingly, when I put the URL in the button code the request was rejected (no cross-origin request allowed) but when after I put the URL in the function it worked.

function toggleCal() {
            var myUrl = "http://mypi.local:8080/remote?action=TOGGLE&module=MMM-CalendarExt";
            console.log("getting " + myUrl)
            var xmlHttp = new XMLHttpRequest();
            xmlHttp.open("GET", myUrl, false); // false for synchronous request
            xmlHttp.send(null);
            return xmlHttp.responseText;
        };

The button code gets mangled here. I had to add spaces

< button onclick="toggleCal()">Calender on/off< /button>
