Backbone events have a variety of methods and a series of the catalog of events. Let’s look at the methods first.
The following are a few methods part of Backbone.Events.
object.on(event, callback, [context]) binds a callback function to an object. The callback method will be called whenever the event is triggered.
object.off([event], [callback], [context]) removes a previously-bound callback function from an object.
object.trigger(event, [*args]) triggers callbacks for the given event or space-delimited list of events.
object.once(event, callback, [context]) creates a backbone.Model, and it extends the backbone.Model class.
object.listenTo(other, event, callback) tells an object to listen to a particular event on another object.
object.stopListening([other], [event], [callback]) informs any object to stop listening to events.
object.listenToOnce(other, event, callback) causes the listenTo method to only occur once before the callback function.
