unsubscribing

pubsub.js

// Given the following namespaced objects

// a widget
Namespace('km.widget.edVolGraph', {

	handle: 'undefined',
	load: function() {
		handle = $.subscribe('xmlFetch', function() {
				// do stuff
		});
	}
});

// a controller
Namespace('km.core', {

	url: 'someDir/someFile',
	fetch: $.get(url, function(xml) {
		$.publish('xmlFetch', [xml]);
	})
});


// launching the widget
km.widget.edVolGraph.load();  // load into a view on main webpage
km.widget.edVolGraph.load();  // load into a view on main webpage

// if a user wants to kill just one of the views
// how can I unsubscribe that one view without
// unsubscribing the other(s)?
