Answer 1

  Response.Write("<script language='javascript'>window.close();</script>");
  Response.Write("<script language='javascript'>self.opener.location.reload();</script>");调换一位置看看。
  Response.Write("<script language='javascript'>self.opener.location.reload();</script>");
  Response.Write("<script language='javascript'>window.close();</script>");
