Ext js - 在TabPanel中动态更改Tab的内容

var tabPanel = Ext.getCmp('myTabPanel');
tabPanel.setActiveTab(1); // 将活动选项卡更改为索引为 1 的选项卡

var tabPanel = Ext.getCmp('myTabPanel');
tabPanel.add({
    title: 'New Tab',
    html: 'This is the content of the new tab'
});

var tabPanel = Ext.getCmp('myTabPanel');
tabPanel.remove(tabToRemove); // 将要删除的选项卡作为参数传递

var tabPanel = Ext.getCmp('myTabPanel');
var activeTab = tabPanel.getActiveTab();
