• 我是TypeScript和Jasmine的新手，对Backbone和Require也是新手，所以我还在尝试将一些片段粘合在一起。*

在一个TypeScript文件的Jasmine测试中，我试图定义一个backbone.Collection。

(...)

class ModelA extends backbone.Model {
    idAttribute: "N";
    constructor(N: number, StringPropertyA: string, StringPropertyB: string, NumericPropertyA: number, NumericPropertyB: number, DatePropertyA: Date, DatePropertyB : Date) {
        super();
        this.attributes.N = N;
        this.attributes.StringPropertyA = StringPropertyA;
        this.attributes.StringPropertyB = StringPropertyB;
        this.attributes.NumericPropertyA = NumericPropertyA;
        this.attributes.NumericPropertyB = NumericPropertyB;
        this.attributes.DatePropertyA = DatePropertyA;
        this.attributes.DatePropertyB = DatePropertyB;
    }
}
            //var OldModelA = backbone.Model.extend({
            //    idAttribute: "N",
            //    constructor: function (N, PropertyA, PropertyB) {
            //        this.N = N;
            //        this.PropertyA = PropertyA;
            //        this.PropertyB = PropertyB;
            //    }
            //});

            var ModelACollection = backbone.Collection.extend({model: ModelA});

            var i = 1;
            var model1 = new ModelA(i++, "Abc", "dfD9"),
                model2 = new ModelA(i++, "Cde", "gdkl"),
                model3 = new ModelA(i++, "Cdy", "grger"),
                model4 = new ModelA(i++, "Zly", "dzeersds"),
                model5 = new ModelA(i++, "Zlz", "sdfsfz");

            var modelArray = [model1, model2, model3, model4, model5];

            var collection1 = new ModelACollection({ models: modelArray });
            var collection2 = new backbone.Collection({ models: modelArray });

(...)

我希望collection1.models和collection2.models是5个元素的数组，但根据Chrome，它们的内容如下：
我想我错过了什么...

进一步搜索类似结果

var collection3 = new backbone.Collection();
        collection3.add(model1);
        collection3.add(model2);
        collection3.add(model3);
        collection3.add(model4);
        collection3.add(model5);
