Question

我在backbone.js中很开心当我用数据创建模型时，我有错误。

首先声明的模型如下;

var verifiedBookPriceSolutionApp = {
    Models :{},
    Collections : {},
    Views :{},
    Templates :{}
}

///BackBone model setting;
     verifiedBookPriceSolutionApp.Models.Journey = new Backbone.Model.extend({
         initialize: function(){}
     });

然后我创建一个模型如下，

    var journey = {"key": "0T", "carrier": "PS", "carrierName": "Ukraine International Airlines", "flight_number": "102", "origin": "AMS", "destination": "KBP", "departure_time": "2013-08-18T13:10:00.000+02:00", "arrival_time": "2013-08-18T16:55:00.000+03:00"}


var JourneyModel = new verifiedBookPriceSolutionApp.Models.Journey(journey);

在这一行中，我有一个错误，如“Uncaught TypeError：Object [object Object]没有方法'apply'”

我无法找到解决方案，为什么会出现这样的错误。

问候，

Answer 1

定义new模型时，请勿在{{1}}上调用Backbone.Model.extend。这样做：

Journey

Answer 2

您在这里创建一个对象：

 verifiedBookPriceSolutionApp.Models.Journey = new Backbone.Model.extend({
     initialize: function(){}
 });

将其更改为：

 verifiedBookPriceSolutionApp.Models.Journey = Backbone.Model.extend({
     initialize: function(){}
 });

Answer 3

而不是这一行，

    var JourneyModel = new verifiedBookPriceSolutionApp.Models.Journey(journey);

尝试以下行：

    var JourneyModel = verifiedBookPriceSolutionApp.Models.Journey.set(journey);

而不是

    verifiedBookPriceSolutionApp.Models.Journey = new Backbone.Model.extend({
     initialize: function(){}
 });

写得像

   verifiedBookPriceSolutionApp.Models.Journey = new Backbone.Model;
