backbone.js - Is it possible to pass url parameter when creating an instance of Backbone Collection object? -

is possible pass url parameter when creating instance of collection object? create array of collections containing data pages.

var collection = backbone.collection.extend({      model: mainmodel,     initialize: function (models,options) {         var self = this;         self.fetch();        } });  var collections = {     news : new collection({url : "../data/news"}),     projects : new collection({url : "../data/projects"}),     home : new collection({url : "../data/home"}) }; 

is possible this, or doing terribly wrong? need create collection each page?

generally want create new collection each type of model
