Very nice demo. I suspect Ian is particularly interested in safari so he
will have to dig into that. My guess is that the BroadcastChannel is a
fairly simple thing built on top of the underlying localstorage mechanism
and I know that works in safari.

Thanks to Ian and Eric for an interesting question and direction.
Following Eric's lead I found (in all but Safari)
a built-in object BroadcastChannel which is what it claims to be. The
following 2 scripts illustrate its use in the
jhs context to perform what Ian requested. Perhaps there are
Ian,
By resources, I meant google. The phrase that will get you started is
'javascript shared local storage'. A search of the JHS scripts will show a
few simple places where it is currently used. But there is no current use
of the very interesting event triggers.

This could be useful. But my Javascript is so poor I can't really say until
I've tried it.

Yes. When I first started thinking about my requirements, this was just the
sort of
Ian (your JHS question),
There is a facility in javascript in the browser called shared memory. JHS
uses this in a very limited way, but I have always wanted to revisit it to
see what else could be done.
One page setting shared memory can trigger an event in the javascript of
the other page. Is
@Raul,
Refresh: 3
…works a treat. Besides giving a conspicuous indication in the Safari
toolbar that the "animated" window is alive and kicking.
All no doubt horribly inefficient. But good enough in the short term for my
experiments.
Mac:Activity Monitor does show the resource usage of both
and see if the Meta Refresh tag is good enough.

That's prett
That's pretty much it. The browser is in control here, and jijx is
only indirectly in control as a result.
Probably the simplest would be to put something like Refresh: 3 in the
http headers in your MYTEMPLATE (before the first blank line). But I
haven't tested that - I probably need to upgrade
Currently I'm hacking it by using Keyboard Maestro to execute a timer which
reloads the message URL every 3 seconds.
I guess much the same thing could be done using Javascript embedded in
message.ijs? – if I knew any Javascript.
Another expedient is to write out the message display to a textfile
Suppose I am a JHS coder, working with the J session (the jijx page), and
have written an app called "message" (say). This generates a page of data
in response to the URL:
http://localhost:65001/message
which I choose to display in a separate browser window. Let's call it the
message window.
