Closing a tab using ascii codes

Question

Ive read earlier that we cannot close the current tab using jQuery or Javascript.

My question is, Is it possible to use the ASCII codes for "ctrl+w" (that is 23) and calling it in jquery/JS to close the current tab?

I tried this code:

<script>
function closethis(){
    $(document).keypress(function(e) {
        if(e.which == 23) {
            alert('Are you sure you want to close?');
        }
    });
}
</script>

but doesnt work.. any leads??

You're trying to send a command (shortcut) to the browser. This is not possible. Otherwise, you would be able to do other things like even close the browser itself (Alt + F4), which obviously doesn't make much sense. — marsze, Dec 04 '14 at 13:41
yeah i know.. was just trying an alternative to close the current tab.. but none are working. I cannot use window.close() in my case as i am not opening a new window using JS..so that. — , Dec 04 '14 at 19:02

No, you cannot close windows your script hasn't opened in any way.

(If your script opened a window with var newWindow = window.open(...), you can close it with newWindow.close().)

The most you can do in windows that you didn't open is show a dialog box when the tab is being closed by the user. For that, see How do I stop a page from unloading (navigating away) in JS? and unload on MDN.
