Answer 1

 var win = new Ext.Window({
                                xtype : "window",
                                title : "My Window",
                                width : 400,
                                height : 250,
                                items : panel,
                                closeAction : 'close',//这里写成 'hide'

Answer 2

如果想要模式窗体可以加上 modal: true

Answer 3

var win = new Ext.Window({
                                xtype : "window",
                                title : "My Window",
                                width : 400,
                                height : 250,
                                items : panel,
                                closeAction : 'close',
                                constrain : true,
                                minizable : true,
                                maximizable : true,
                                layout : 'fit',
                                tools : [{
                                            id : 'save'
                                        }, {
                                            id : 'unpin'
                                        }, {
                                            id : 'plus'
                                        }],
                                buttons : [{
                                            text : "登录",
                                            listeners : {
                                                'click' : function() {
                                                    Ext.Msg.alert('登录成功',
                                                            "欢迎登录");                                                }
                                            }
                                        }, {
                                            text : '注销',
                                            listeners : {
                                                'click' : function() {
                                                    Ext.Msg.alert('失败', "已注销",function(){
                                                    
                                                        win.close();
                                                        
                                                    });
                                                    
                                                }
                                            }
                                        }]
                            })这段代码放按钮的外面去。每次按增加你还又建一个window

Answer 4

+对，这样每次创建window浪费资源的，创建dom也是要时间的
而且你的window中有id，每次创建个id就重复了；
建议用closeAction：hide模式；关闭即隐藏掉。然后再显示的时候就win.show
当panel加载的时候就插件window，后面调用show方法即可

Answer 5

谢谢几位，已经解决了。
改了两个地方：
1、var win = new Ext.Window({……})在外面独立定义，且
text : '注销',
  listeners : {
  'click' : function() {
  Ext.Msg.alert('失败', "已注销",function(){
    
  win.close(); //修改为win.hide();2、grid的tbar的增加栏位修改如下，handler实现不了，所以使用了listeners：
{
text : '增加',
tooltip : 'Add a new row',
iconCls : 'add',
listeners : {
'click' : function() { // win.hidden(this);
win.show(); }
}
}
