我在煎茶觸摸下面的視圖代碼2

Ext.define('WL.view.Categories', {

    }, 

    items: [

      xtype: 'toolbar',

     } 
    ], 

    loadingText: null, 

    listeners: { 
     order: 'before', 
     select: function() { 
      return false; 
     }, 
     itemtap: function(dataview, index, target, record, evt) { 

      var el = Ext.get(evt.target), 
       fireEvent; 

      if (el.dom.nodeName == 'B') el = el.parent(); 

      WL.currentMovie = record; 

      if (el.hasCls('seen')) { 
       fireEvent = el.hasCls('selected') ? 'unSeen' : 'seen'; 
       el.toggleCls('selected'); 
      } else if (el.hasCls('want')) {

       '{% } %}', 
      '</div>', 

     '</div>' 
    ) 

    }  // end of the categories list 
    ] 
}, 

initialize: function() { 
    this.callParent(); 

    // Enable the Tap event on the profile picture in the toolbar, so we can show a logout button 
    var profilePic = Ext.getCmp('fbProfilePic'); 
    if (profilePic) { 
     profilePic.element.on('tap', function(e) { 
      profilePic.fireEvent('tap', profilePic, e); 
     }); 
    } 
} 
}); 

我已經定義的xtype到我的視圖，所以可在我的控制器代碼引用它

這是我控制器代碼

Ext.define('WL.controller.Categories', { 
extend: 'Ext.app.Controller', 

config: { 
    refs: {  
     categories: 'categories', 
     List: 'list' 
    }, 

    control: { 
     list: { 
      tapMovie: 'onMovieTap'  // the function that will be created when a movie is tapped 
     } 

     } 

}, 
slideLeftTransition: { type: 'slide', direction: 'left' }, 
    slideRightTransition: { type: 'slide', direction: 'right' }, 

onMovieTap: function() { 
    Ext.Viewport.animateActiveItem(this.getCategories(),this.slideRightTransition);     
} 
}); 

我的主要問題是，在控制器get函數getCategories()沒有工作，所以我可以瀏覽到我的幻燈片右效果圖，我認爲，我的問題是在定義xtype，你能給我一個線索，定義正確的xtype，給出我嘗試使用alias:widget.categories但它沒有工作。

Answer 1

你的配置應該是這樣的：

config: { 
    refs : { 
     categories : { 
      autoCreate: true, 
      selector: '#categories_itemId', 
      xtype: 'categories' 
     }, 
     List : { 
      // do the same thing for 'List' 
     } 
    }, 
    control: { 
     ... 
    }, 
    ... 
}, 
... 

注意，選擇是你的view的itemId所以給你的categories view一個的itemId（你可以看到我只是做了一個了）。
