[Mapbender-dev] Reload single WMS-Layer

[Christoph Ratke]

Hey Uli,
wouldn't it make sense to adapt the function setSingleMapRequest? To
always set a different GetMap request it would be sufficient to add the
TIME parameter and assign the timestamp to it (ts=mb_timestamp(), it is
already there). Usually, if you call this setSingleMapRquest you don't
want the browser to cache your single map anyway. What do you think?

Rainer,
if you want to automatically refresh your map request you could use the 
javascript function setTimeout similar to this

var loop = true; // set this var to false to stop the loop
function functionA() {
        if (loop) {window.setTimeout("functionA", 
		<milliseconds to wait>);}
        else {top.close(); } // stop the timeout
        <call getMap or zoom function>
}
I would recommend to write your own javascript or php module

regards,
Christoph Ratke
