not possible

Why not? I think I answered. You can capture closing of the page, and it can close another, as you can remember the child windows in the script of the parent after creation.
~~If one wanted a "child" window to close the "parent", it would be a problem, but when a parent closes child, it'll work fine...~~
I basically answered, please see.

The request is quite questionable. Why doing so?

However, these pages will give you the idea:
http://www.w3schools.com/jsref/obj_window.asp[^],
http://www.w3schools.com/jsref/met_win_close.asp[^],
http://stackoverflow.com/questions/6622461/how-to-capture-browser-close-event-in-javascript[^].

Does it make your problem clear?

[EDIT]

As we had a little argument with aspnet_regiis, this is the code I've just tested, so it proves my point:

XML

<html>
<head>
   <title>Child window and window.onbeforeunload demo</title>
   <script language="Javascript"><!--
      var newWin;
      function Show() {
         newWin = window.open(
            "",
            "toolbar=no,location=no"
         );
         newWin.name = "Child window";
      }
      function CloseIt() {
         alert("Closing a child window"); newWin.close();
      }
    --></script>
</head>

<body>

<script language="Javascript"><!--
    window.onbeforeunload = function(e) {
        CloseIt();
    };
--></script>

<button accesskey="S" onClick="Show()"><u>S</u>how</button></br>

</body>
</html>

By the way, despite of my initial comment, closing a "parent" window from a child one is also possible, due to the property opener:

Dear SA...With due respect to you, I want to put forth that the two browser instances are independent of each other and one does not know about each other... We cannot close one browser instance from another.

I would be more then happy if you can prove me wrong. I still insist that one browser instance cannot be closed from another and there is no such thing like a parent or a child window. Its a logical parent and child window. technically a parent window does not know about child window ( other than the window properties used while opening the child window)....

Sergey Alexandrovich Kryukov 14-Mar-13 15:36pm

I see your point, but... I think that they become dependent when you store a window reference in the parent page... A while ago, I did something very similar (the code is on my Web site, a photo album; you can see it). I did not close the child window (which would look stupid to me, but I replaced its content on some anchor click in the parent window. You should agree that if I can do it, it means that one page actually keeps the reference to the window of another page and can control it, in particular, close it.

Do you still need to see such code..? Or you can try by yourself.

I tested it with different (old) browsers, it works now; and even when people complained about something, nobody observed that my mechanism failed...

OK, I got the fully-working demo code to show you. Please try.
Click on the button "Show" first, than close the first ("parent") window. It should close the "child" one.

Will you change your opinion now?

Surely.. I will try it and will let you know ..And thanks for the complete working code...

bbirajdar 15-Mar-13 2:59am

Amazing.. It works....Thank you very much for correcting me... I wish I could have voted you +10

Sergey Alexandrovich Kryukov 15-Mar-13 9:33am

It does. Thank you very much.
