在下劃線模板中使用JSON對象 - Backbone.js

Question

我正在研究日曆風格的骨幹應用程序，但對它來說相當新穎。我一直在這上面用了12個多小時，仍然無法讓我的模板填充JSON數據。

下面是一些代碼，我今天寫的：

型號

var CalendarDay = Backbone.Model.extend({ 
    defaults: function() { 
     return { 
      title: "No days for this event", 
      done: false 
     }; 
    }, 
    initialize: function() {} 
}); 

var calendarItem = new CalendarDay({ 
    urlRoot: URL 
}); 

收集

var Calendar = Backbone.Collection.extend({ 
    model: CalendarDay, 
    url: URL 
}); 

查看

var CalendarView = Backbone.View.extend({ 
    template: _.template($('#days').html()), 
    initialize: function() { 
     this.collection = new Calendar(); 
     this.collection.fetch(); 
     this.collection.bind("reset", this.render, this); 
     this.loadTimes(); 
    }, 
    render: function() { 
     var JSON = this.collection.toJSON(); 
     this.$el.html(this.template(JSON)); 
     console.log(JSON); 
    }, 
    listDays: function() { 

    } 

}); 

var calendarView = new CalendarView({ 
    model: calendarItem 
}); 

，這裏是我GETT來自服務器的JSON：

（從執行console.log） 連接

0: Object 
activity_logs: Array[0] 
attendee_code: "BBNVKBGT" 
attendee_fee: "0" 
cego_fee: "0" 
certificate_fee: "0" 
created_at: "2013-02-13 11:29:03" 
days: Array[1] 
description: "A wonderful serenity has taken possession of my entire soul, like these sweet mornings of spring which I enjoy with my whole heart. I am alone, and feel the charm of existence in this spot, which was created for the bliss of souls like mine." 
disciplines: Array[3] 
done: false 
fee_transaction_id: "0" 
id: "102" 
marketing_materials: Array[0] 
messages: Array[0] 
name: "My very first event" 
organization_id: "1" 
start_at: "2013-02-28 00:00:00" 
state_id: "38" 
states: Array[2] 
title: "No days for this event" 
updated_at: "2013-02-13 11:29:04" 
venue_id: "55" 

是我的控制檯日誌，JSON的一個更好的視野。

更新：這是我的字符串化JSON：

[{"title":"No days for this event","done":false,"id":"102","organization_id":"1","state_id":"38","venue_id":"55","name":"My very first event","description":"A wonderful serenity has taken possession of my entire soul, like these sweet mornings of spring which I enjoy with my whole heart.

這裏是我的模板視圖：

<script id="days" type="text/template"> 
      <a class="btn small-btn marginRight"></a> 
    </script> 

只是想我要在這裏補充，如果我使用的模板標籤上面諸如<% title %>，我得到錯誤Uncaught ReferenceError: title is not defined

我筋疲力盡，自學中堅比人們想象的要難。任何幫助讓這個球再次滾動將是真棒謝謝。

Answer 1

修改視圖

this.$el.html(this.template(JSON)); 

到

this.$el.html(this.template({days: JSON})); 

修改模板

<script id="days" type="text/template"> 
    <% _.each(days, function(day) { %> <a class="btn small-btn marginRight"><%= day.title %></a> <% }); %> 
</script>
