这是我的视口设置：

var viewport = new Ext.Viewport({
    layout:'border',enableTabScroll:true,deferredRender:true,items:[
        new Ext.BoxComponent({ // raw
            region:'north',el: 'north',height:32
        }),{
            region:'west',id:'west-panel',title:'West',split:true,width: 200,minSize: 175,maxSize: 400,collapsible: false,margins:'0 0 0 5',layout:'accordion',deferredRender: true,layoutConfig:{
                animate:true
            },items: [{
                contentEl: 'west',title:'Navigation',border:false,iconCls:'nav'
            }]
        },new Ext.TabPanel({
            region:'center',id:'center',activeTab:0,items:[{
                contentEl:'center1',title: 'Close Me',closable:true,layout:'fit',autoScroll:true
            }]
        })
     ]
});

这是我的添加标签代码：

Ext.get("addplace").on('click',function() {
    centerTabs = Ext.getCmp('center');
    tab = centerTabs.add(new Ext.TabPanel({
        iconCls: 'tabs',id: 'add_place_tab',autoLoad: {url: '/admin/addplace',scripts : true,},title: 'Add Place',loadMask: false,closable:true
    }));
    centerTabs.setActiveTab(tab);
});

提前致谢！
