一、属性
ownerCt：得到当前对象所在的容器。
items：集合列表
二、应用举例

复制代码代码如下:

 
 Ext.onReady(function(){ 
  
 var _window = new Ext.Window({ 
  
 title:"测试窗体", 
  
 layout:"form", 
  
 width:300, 
  
 plain:true, 
  
 items:{ 
  
 id:"name", 
  
 xtype:"textfield", 
  
 fieldLabel:"姓名" 
  
 }, 
  
 buttons:[{ 
  
 text:"确定", 
  
 handler:function(){ 
  
 alert(this.ownerCt.ownerCt.items.first().getValue()) ; 
  
 alert(this.ownerCt.ownerCt.items.itemAt(0).getValue()) ; 
  
 alert(Ext.getCmp("name").getValue()) ; 
  
 } 
  
 }] 
  
 }) ; 
  
 _window.show() ; 
  
 }) ;
