Parametrized events in Controllers

[PatrickR]

Hi,

I pretty much want to to what is described in this discussion:
http://groups.google.com/group/javascriptmvc/browse_thread/thread/8a63db20208dcfdd/d3ffe95160e26c88?lnk=gst&q=parameterized+action+names+#d3ffe95160e26c88

i.e. have parametrized event listeners. From the above I gather that
this has been tried or maybe even implemented. Is it?

I've tried something like the following without success:

$.Controller.extend('Foo',{},
{
_topics: ['bar','bim'],
'myevent.{_topics[1]}.** subscribe': function(topic, data) {
// do stuff
}
});

The main reason behind wanting to do this is that I'd like all topics
namespaced and available through a separate class. This would makes
documentation better and enables tab completion in good IDEs. So my
events would actually look like
'{MyEventClass.SomeEventTopic}.**': ... Maybe there is a better way to
achieve that?

Thanks,
/Patrick

Parameterized only happens with the options (2nd param to a controller)

You could so it like:

$.Controller.extend("Foo",{

  defaults: {

    namespace : MyEventClass.Namespace

  } 

},{

  "{namespace}.created subscribe" : function( ..) { ... }

})

Whatever is in MyEventClass.Namespace when the class is created would be {namspace} in the action.  You could overwrite this when creating controller instances:

$('.bar').foo({namespace: "somethingElse"})
