Problem

Refer - Bypass IE “The webpage you are viewing…” pop up[^].

Quote:
Your JavaScript code can only close a window without confirmation that was previously opened by window.open(). This is an intentional security precaution because a script running on a webpage does not own the window, and by closing it discards the browsing history in that window.

The workaround is to either have a "welcome page" or otherwise some sort of page that pops up the window you want to close with window.open in the first place, or to tell your users to modify their browser security settings to allow your application to close their windows.

So, the problem is that you are trying to close "index.aspx", which you have not opened by javaScript window.open. You can only close the window which is opened by winow.open.

Solution

In that case, you may try workarounds mentioned in the below links -

1. Close window without the prompt message in IE7[^].
2. The webpage you are viewing is trying to close this window warning in Internet Explorer[^]
