❶ 求解Extjs问题： 通过树节点，打开一个页面添加到tabpanel,关闭之后，再次打开不显示页面怎么解决
Ext.getCmp("centerPanel").remove(e);
你都remove掉了怎么可能还show回来，show对应的应该是hide
❷ extjs5中tabpanel鼠标右键全部关闭如何实现
给你例子参考，关联到右键就可以了

❸ Extjs：关于关闭TabPanel标签的问题
取得窗口的引用
在下一个窗口打开时
用前一个窗口的引用关闭
❹ extjs 如何关闭当前整个网页
Extjs中关闭整个页面需要用parent对象窗口打开的window对象。
例如：
有a,b两个页面，a页面为主页面，有按钮一个，点击按钮弹出一个windows对象，在其中显示b页面。b页面中也有一个按钮，点击关闭窗口。
a.htm (部分代码)
<script type="text/javascript">
function openWindow(id,title,url,width,height){
var win = Ext.get(id)
if (win) {
win.close();
return;
}
win = new Ext.Window({
id:id,
title:title,
layout:'fit',
width:width,
height:height,
closeAction:'close',
collapsible:true,
plain: false,
resizable: true,
html : ''
});
win.show();
}
function myfunction(){
openWindow('b-win','窗口中打开b页面','b.htm',400,300);
}
</script>
<input type="button" name="button1" value="打开窗口" onClick="myfunction()">
b.htm（部分代码）
<script type="text/javascript">
function closewin(){
var win = parent.Ext.getCmp('b-win');
if (win) {win.close();}
}
</script>
<input type="button" name="button1" value="关闭a打开的窗口" onClick="closewin()">
