if (window.opener<>null || !window.opener.closed)
{
window.opener=null;
window.opener.close();
}

if (window.opener!=null || !window.opener.closed)
<HTML>
<HEAD>
<TITLE>window.closed Property</TITLE>
<SCRIPT LANGUAGE="JavaScript">var newWindvar isIE3 = (navigator.appVersion.indexOf("MSIE 3") != -1) ? true : falsefunction newWindow()
{
newWind = window.open("","subwindow","HEIGHT=200,WIDTH=200")
// take care of Navigator 2
if (newWind.opener == null)
{
newWind.opener = window
}
setTimeout("finishNewWindow()", 100)
}
function finishNewWindow()
{
var output = ""
output += "<HTML><BODY><H1>A Sub-window</H1>"
output += "<FORM><INPUT TYPE='button' VALUE='Close Main Window'"

  newWind.document.close()

if (!self.opener.closed)
    {    window.opener.close();
    }
if (window.opener<>null || !window.opener.closed)

    window.opener.close();

哈哈.谢谢，我都没有注意到！！很久没有用Javascript了。if (window.opener!=null || !window.opener.closed)
{
    window.opener.opener=null;
    window.opener.close();
}
