    You aren’t assigning the result of the replace method back to your variable. When you call replace, it returns a new string without modifying the old one.

    For example, load this into your favorite browser:

    <html><head></head><body>
    <script type="text/javascript">
        var str1 = "a,d,k";
        str1.replace(/\,/g,"");
        var str2 = str1.replace(/\,/g,"");
        alert (str1);
        alert (str2);
    </script>
</body></html>

    In this case, str1 will still be "a,d,k" and str2 will be "adk".

    If you want to change str1, you should be doing:

    var str1 = "a,d,k";
str1 = str1.replace (/,/g, "");
