手柄代碼有什麼問題？

嘿所以我想從下劃線切換到車把，但沒有任何模型渲染，但模板正在改變。另外，當editTemplate通過單擊編輯按鈕顯示時，＃{firstName}等顯示爲未定義。手柄代碼有什麼問題？

在我的佈局jade文件中，我包含了所有相應的文件，jquery，下劃線，主幹和車把。

這是我main.js文件

(function() { 
    window.App = { 
     Models: {}, 
     Collections: {}, 
     Views: {}, 
     // Templates: {}, 
     Router: {} 

    }; 

    // MODEL 
    App.Models.User = Backbone.Model.extend({ 
     defaults: { 
      firstName: 'first', 
      lastName: 'last', 
      email: 'Email', 
      phone: '222', 
      birthday: 'date' 
     }, 

     validate: function (attrs) { 
      if (!attrs.firstName) { 
       return 'You must enter a real first name.'; 
      } 
      if (!attrs.lastName) { 
       return 'You must enter a real last name.'; 
      } 
      if (attrs.email.length < 5) { 
       return 'You must enter a real email.'; 
      } 
      if (attrs.phone.length < 10 && attrs.phone === int) { 
       return 'You must enter a real phone number, if you did please remove the dash and spaces.'; 
      } 
      if (attrs.city.length < 2) { 
       return 'You must enter a real city.'; 
      } 
     }, 

     initialize: function() { 
      this.on('invalid', function (model, invalid) { 
       console.log(invalid); 
      }); 
     } 

    }); 



    //VIEW 
    App.Views.User = Backbone.View.extend({ 
     model: App.Models.User, 
     el: 'user', 
     //tagName: 'div', 
     //id: 'user', 
     //className: 'userProfile', 


     initialize: function(){ 

     }, 

     render: function() { 
      var template = Handlebars.compile($("#userTemplate").html()); 
      var editTemplate = Handlebars.compile($("#userEditTemplate").html()); 

      this.$el.html(this.template(this.model.toJSON())); 
      return this; 
     }, 

     events: { 
      'click button.edit': 'editProfile', 
     // 'click button.save': 'saveEdits', 
      'click button.cancel': 'cancelEdits' 
     }, 

     editProfile: function() { 
      this.$el.html(this.editTemplate(this.model.toJSON())); 

     }, 


     cancelEdits: function() { 
      this.render(); 
     } 

    }); 
    //start history service 
    Backbone.history.start(); 

    var user = new App.Views.User({model: new App.Models.User()}); 
    user.render(); 
})();

如果你的JavaScript在DOM建造之前的頁面的進口機頭，到模板中的這些引用都不會滿意。 – Pointy

我將腳本main.js文件移動到底部加載，現在只是不呈現，但我沒有看到任何錯誤？ – Lion789

'el：'用戶'並不意味着你的想法，那個選擇器會尋找一個''元素... –

如果任何人希望看到的答案，這是基本上是調用這個錯誤

#{firstName}

，而正確的使用感：

{{firstName}}
