original string is "a,d,k" I want to remove all "," and make it to "adk". I tried: "a,d,k".replace(/,/,"") but it doesn't work. Thanks in advance.
thanks for quick reply, but I tried replace() and it doesn't work.

A:
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 ",".

A:
You can try something like:
var str = "a,d,k";
str.replace(/,/g, "");

A:
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, "");
