闭包没处理好

这样试试

AdminCustomer=function()
2. {
var PackUp=this;//闭包对象
3. this.editCustomerTypeWindow=new Ext.Window
4. (
5. {
6. title:'添加修改客户信息',
7. border:false,
8. width:700,
9. buttonAlign : 'center',
10. height:250,
11. autoScroll:true,
12. layout:'border',
13. renderTo:Ext.getBody(),
14. closeAction:'hide',
15. style:"text-align:center",
16. modal:true,
17. closable:true,
18. items:
19. new Ext.FormPanel
20. (
21. {

23. items:

25. {
26. xtype:'treecombo',
