学习ExtJS（六） 访问容器对象

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

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() ;            
    }) ;
