JS 问题

window.ope("","OrgSelect","toolbar=yes,left=0,top=0,Width=1280,Height=930,location=yes,directories=no,status=yes,scrollbars=yes,menubar=no,resizable=yes");document.LoginForm.target = "OrgSelect";document.LoginForm.submit();if(window.name != "OrgSelect"){window.opener = null;window.close();这段代码是什么意思？尤其是 document.LoginForm.target = "OrgSelect";  document.LoginForm.submit();
