Ext.onReady(function() {
            //
            var tabs = new Ext.TabPanel({
                renderTo: 'div0',
                width: 750,
                activeTab: 0,
                frame: true,
                defaults: { autoHeight: true },
                items: [
                    { contentEl: 'div1', title: '标题1' },
                    { contentEl: 'div2', title: '标题2' }
                ]
            });

        });
