Remove listener for a Backbone event

Question

I am wondering how would I remove a listener to Backbone.history.on()? .off() did not work for me.

Backbone.history.on('all', function() {
  doStuff();
});

Answer 1

off works as it should be, and here's a Router which proves it:

var MyRouter = Backbone.Router.extend({
    routes: {
        'off': 'offAll',
        '*actions': 'index',

    },

    initialize: function(opt) {

        Backbone.history.on('all', this.all);
    },

    index: function() {
        console.log('route');

    },

    offAll: function() {
        console.log('offAll');

        // remove only this one listener
        Backbone.history.off('all', this.all);
    },

    all: function(){
        console.log('all test');
    }

});

Navigating to anything other than #/off will display :

route
all test

Then, navigating to #/off will display:

offAll

Then, all test never shows up.

Backbone's event .off function

// Removes just the `onChange` callback.
object.off("change", onChange);

// Removes all "change" callbacks.
object.off("change");

// Removes the `onChange` callback for all events.
object.off(null, onChange);

// Removes all callbacks for `context` for all events.
object.off(null, null, context);

// Removes all callbacks on `object`.
object.off();
