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>'
