Massimo Lusetti commented on TAP5-569:
--------------------------------------

Does this still desirable?

Maybe when the new latest features and work dedicated to js in tapestry is settled this could gain attention...

> People keep asking for an easy way to activate zones from their own javascript.
> I have created such a function for our project, but this easy/small convenience method should be in Tapestry core proper..
> Tapestry.activateZone( zoneId, url )
> and now with the multi-zone support, I wonder if zoneId if even required.  It could be null, or another method could be created too:
> Tapestry.activateZones( url )
> Below is the js that I added to my project:
> Tapestry.activateZone = function ( zoneId, url ) {
>         var zoneManager = Tapestry.findZoneManagerByZoneId( zoneId );
>         if ( zoneManager != null ) {
>                 zoneManager.updateFromURL( url );
>         }
> };
> Tapestry.findZoneManagerByZoneId = function( zoneId ) {
>         var zoneElement = $(zoneId);
>         if (!zoneElement) {
>                 Tapestry.ajaxError("Unable to locate Ajax Zone '#{id}' for dynamic update.", { id:zoneId});
>                 return null;
>         }
>         var manager = $T(zoneElement).zoneManager;
>         if (!manager) {
>                 Tapestry.ajaxError("Ajax Zone '#{id}' does not have an associated Tapestry.ZoneManager object.", { id :zoneId });
>                 return null;
>         }
>         return manager;
> };
