最后,我们要定义表示Todo item的model和collection。

Todos.js:

TodoMVC.module('Todos', function(Todos, App, Backbone, Marionette, $, _){ // Todo Model // ---------- Todos.Todo = Backbone.Model.extend({ localStorage: new Backbone.LocalStorage('todos-backbone'), defaults: { title : '', completed : false, created : 0 }, initialize : function() { if (this.isNew()) this.set('created', Date.now()); }, toggle : function() { return this.set('completed', !this.isCompleted()); }, isCompleted: function() { return this.get('completed'); } }); // Todo Collection // --------------- Todos.TodoList = Backbone.Collection.extend({ model: Todos.Todo, localStorage: new Backbone.LocalStorage('todos-backbone'), getCompleted: function() { return this.filter(this._isCompleted); }, getActive: function() { return this.reject(this._isCompleted); }, comparator: function( todo ) { return todo.get('created'); }, _isCompleted: function(todo){ return todo.isCompleted(); } }); });
