骨幹 - get方法不返回輸出

Question

我是Backbone.js的新手，我有一個數據集，分配給查看，但我無法獲取數據，而我控制檯，任何人告訴我什麼是錯的用我的代碼？

代碼：

var model = Backbone.Model.extend({ 
    data:[ 
     {text:'Google',href:"http://www.google.com"}, 
     {text:'Yahoo',href:"http://www.yahoo.com"}, 
     {text:'Bing',href:"http://www.bing.com"} 
    ] 
}); 

var View = Backbone.View.extend({ 
    initialize:function(){ 
     this.render(); 
    }, 
    render:function(){ 
     var data = this.model.get('data'); 
     console.log(data);  
    } 
}); 

var myView = new View({model:model}); 

我得到的錯誤是在這裏：

TypeError: this.model.get is not a function 
[Break On This Error] 

var data = this.model.get('data');

您需要實際實例化模型;使用extend只是創建了Backbone.Model原型的擴展。 The following creates a new instance of Backbone.Model，並用數據初始化它：

var model = new Backbone.Model({ 
    data:[ 
     {text:'Google',href:"http://www.google.com"}, 
     {text:'Yahoo',href:"http://www.yahoo.com"}, 
     {text:'Bing',href:"http://www.bing.com"} 
    ] 
}); 
var myView = new View({ model: model });

如果你想要把數據模型本身的類型，那麼你可以使用defaults屬性：

var Model = Backbone.Model.extend({ 
    defaults: { 
     data:[ 
      {text:'Google',href:"http://www.google.com"}, 
      {text:'Yahoo',href:"http://www.yahoo.com"}, 
      {text:'Bing',href:"http://www.bing.com"} 
     ] 
    } 
}); 
var model = new Model(); 
var myView = new View({ model: model });
