In backbone.js documentation it says:
To make a handy event dispatcher that can coordinate events among different areas of your application: var dispatcher = _.clone(Backbone.Events)
Can anyone explain how to implement the dispatcher to communicate from one view to another? Where do I have to place the code in my app?
Here is a good article about using an event aggregator.
You will probably have some kind of App Controller object, which will control the flow of the app, creating views, models, etc. This is also a good place for the event aggregator.
From my point of view, I think that article explains it pretty well.
