Hi arpan me again,
We'll leave the other thread open.
Adam may have a much better solution for your duplicate
problem. This uses "indexOf" to see if the value already
exists in the textbox..

Thanks, my dear friends, for all your suggestions & inputs but here's the simplest way to do it:
No RegExp, no replace()! Just substring().....that's it!!!
Regards,
Arpan
Code:
<script language="JavaScript">
var str="(mymail@server.com)"
str=str.substring(1,str.length-1)
</script>No RegExp, no replace()! Just substring().....that's it!!!

Hello Lrnmore,
I tried out your idea regarding my 'duplicate' query. It works fine but there's a small problem. The problem is as soon as the empty textbox gets populated with the 1st mail address, a semi-colon (
also gets appended at the end. I want the semi-colon to be appended if & only if the user selects another e-mail address. Here's an example:
User 1st selects
. The textbox should now display
But using your code, the textbox now displays
Any workaround to this???
