there are a couple transports availble in the dojox.cometd client, long
polling being the default. subscribe() would issue a command to the server
(ch: /cometd/meta) to alert the server it wants messages published on some
topic. when something comes to the server
via someone's publish(), anyone subscribed to that topic() gets that data.
for instance, I did a magnet "demo", is was basically:
connect(onDragStart) -> publish("/magnet/moving",{ node: magnetId });
connect(onDragEnd) -> publish("/magnet/done",{
coords:$("magnet").dimensions(),
magnet: magnetId
});
subscribe("/magnet/done",function(o){
var x = o.data.x +"px";
var y = o.data.x +"px";
$(o.data.magnet).css({ top: y, left: x });
});
