ajax - javascript redirect & replace -

- 

<script type = "text/javascript">     var r = window.location.href;     if (r.match(/#|%23/)) {         r = r.replace(/#|%23/gi, \"@num@\");         window.location.href = r;     } </script>

this script redirect page , replace # symbols @num@ in url (don't ask why)...

i'm trying modify script doesn't replace "#" if @ end of url

example:

http://www.example.com/test.php?f=abc#def

will become

http://www.example.com/test.php?f=abc@num@def

but link:

http://www.example.com/test.php?f=abc#def#

will become:

http://www.example.com/test.php?f=abc@num@def#

use positive lookahead guarantee there @ least 1 more character:

/(#|%23)(?=.)/g
