我有下一个脚本:

var Game = Backbone.Model.extend({});

var GamesCollection = Backbone.Collection.extend({
    model: Game
});

var games = new GamesCollection();

var portal = new Game({name: 'Tetris', year: '2017'});
games.add(portal);

console.log(games.get(0));

为什么"games.get(0)"返回'undefined'？可能是我用get方法不正确吗？
