how to remove "," from a string in javascript

Solution 1:

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, "");

Solution 2:

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 ",".

Solution 3:

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>
