    If you need a number greater than 999,999.00 you will have a problem.
    These are only good for numbers less than 1 million, 1,000,000.
    They only remove 1 or 2 commas.

    Here the script that can remove up to 12 commas:

    function uncomma(x) {
  var string1 = x;
  for (y = 0; y < 12; y++) {
    string1 = string1.replace(/\,/g, '');
  }
  return string1;
}

    Modify that for loop if you need bigger numbers.

    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, "");

    If U want to delete more than one characters, say comma and dots you can write

    <script type="text/javascript">
  var mystring = "It,is,a,test.string,of.mine" 
  mystring = mystring.replace(/[,.]/g , ''); 
  alert( mystring);
</script>

    <script type="text/javascript">var s = '/Controller/Action#11112';if(typeof s == 'string' && /\?*/.test(s)){s = s.replace(/\#.*/gi,'');}document.write(s);</script>

    It's more common answer. And can be use with s= document.location.href;

    Use String.replace(), e.g.

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

    Note the g (global) flag on the regular expression, which matches all instances of ",".

    You can try something like:

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