   ]
}

检索上述数据的 url 是 /products/index.json

检索产品数据第 2 页的 url 是 /products/index.json/page:2

我已将以下内容写为集合

<script type="text/javascript">
    (function ($) {
        window.AppView = Backbone.View.extend({
            el: $("body")
        });
        var appview = new AppView;

        var Products = Backbone.Collection.extend({
            model: Product, 
            url: '/products/index.json'
        });

        Products.fetch();
    })(jQuery);
</script>

我想我Products写错了集合。

请指教。

更新

这是我的新代码http://jsfiddle.net/Cw6PT/

这是我现在收到的错误消息： Uncaught TypeError: Object function (){return c.apply(this,arguments)} has no method 'fetch'

你Products是一个Collection类，而不是一个Collection对象。将您的代码更改为

new Products().fetch()

或者

var Products = new (Backbone.Collection.extend(...))

应该管用。此外，如果您想自定义如何解析 JSON 回复，您可以覆盖collection.parse。
