Writing a Handler that Handles the Widget Event

After this task is complete, the plotCity application will be able to populate the thisCity combobox widget with new data when the user selects a state from the thisState widget.

1. Open the glue.js file, located in plotCity/Web Pages, in the editor pane.

2. At the end of the glue.js file, add the following subscribe function:

   jmaki.subscribe("/cb/getState/*", function(args) {
   	var message = args.value;
   	jmaki.doAjax({method: "POST",
   	url: "Service?message=" + encodeURIComponent(message),
   	callback: function(_req) {
   		var tmp = _req.responseText;
   		var obj = eval("(" + tmp + ")");
   		jmaki.publish('/cb/setValues', obj);
   		// handle any errors
   		}
   	});
   });
