MSCRM 2011 Javascript save and close

In 2011 This script doesn't work:
1. Xrm.Page.data.entity.save();
2. window.close();

CRM 4.0 Code (Worked great):

 crmForm.Save();

 window.close();

The solution in 2011:

Xrm.Page.data.entity.save("saveandclose")

The right why in 4.0
crmForm.SaveAndClose();


and just for closing the window
Xrm.Page.ui.close();
