clonecollection.clone() Returns a new instance of the collection with an identical list of models.

toJSONcollection.toJSON([options]) Return an array containing the attributes hash of each model (via toJSON) in the collection. This can be used to serialize and persist the collection as a whole. The name of this method is a bit confusing, because it conforms to JavaScript's JSON API. var collection = new Backbone.Collection([ {name: "Tim", age: 5}, {name: "Ida", age: 26}, {name: "Rob", age: 55} ]); alert(JSON.stringify(collection));

wherecollection.where(attributes) Return an array of all the models in a collection that match the passed attributes. Useful for simple cases of filter. var friends = new Backbone.Collection([ {name: "Athos", job: "Musketeer"}, {name: "Porthos", job: "Musketeer"}, {name: "Aramis", job: "Musketeer"}, {name: "d'Artagnan", job: "Guard"}, ]); var musketeers = friends.where({job: "Musketeer"}); alert(musketeers.length);

If no context is specified, all of the versions of the callback with different contexts will be removed. If no callback is specified, all callbacks for the event will be removed. If no event is specified, callbacks for all events will be removed. // Removes just the `onChange` callback. object.off("change", onChange); // Removes all "change" callbacks. object.off("change")
