Extjs中TabPane如何嵌套在其他网页中实现思路及代码

var tabPanel = new Ext.TabPanel({
activeTab: 0,
region:'center',
layoutOnTabChange : false,
deferredRender: true,
items:[

{
title: '百度',
layout: 'fit',
height: 375,
id: 'training_grief_rep_tab_4',
border: false,
deferredRender: false,
//items : new TrainingBriefSummaryItem({sunmmaryId: tariningId}),
autoScroll : true,
html:' <iframe scrolling="auto" frameborder="0" width="100%" height="100%" src="'+'http://www.baidu.com'+'"> </iframe>'
}
]
});
