Answer 1

您可以將格式功能模板的一部分：

Ext.application({ 
    name: 'Fiddle', 

    launch: function() { 
     Ext.Viewport.add({ 
      xtype: 'list', 
      itemTpl: ['{name:this.doIt}', { 
       doIt: function(v) { 
        return v + ' go'; 
       } 
      }], 
      store: { 
       fields: ['name'], 
       data: [{ 
        name: 'A' 
       }] 
      } 
     }); 
    } 
});

      '<tpl for=".">', 
      '{[this.formatValue(values.price)]} ...', 
      '</tpl>', { 
      formatValue: function(v) { 
       return v + ' €'; 
      }
