JS implements closing the current page without popping up a prompt box

This article provides an example of how JS implements closing the current page without popping up a prompt box.Share it for your reference, as follows:

Close the current page and open a new one (without prompting)

function closeWinAndOpen(url) {
  var sWinName = "LR"+parseInt(Math.random() * 100000000);// Processing with random numbers WinName
  window.open(url,sWinName, 'toolbar=no,location=no,directories=no,status=yes,menubar=no,scrollbars=no,resizable=yes,copyhistory=yes');
  closeWin();
}

Close the current page:

function closeWin() {
  window.opener=null;
  window.open('','_self');
  window.close();
}

Close parent page:

Response.Write("<script>window.top.opener=null;window.parent.close();</script>")

(window.top.close() also works)

Set window.opener=null to not show: "The page you are viewing is trying to close the window, do you want to close the window?"
