In my JS I added a trim() method to a String object to trim whitespaces in
a string, hoever, it does not work. A value  in the string is the same
before and aftertrim() is called. What am I doing wrong?



<script language="javascript">

String.prototype.trim = function()
{

   return this.replace(/(^\s*)|(\s*$)/g,"");
}

function saveTheBankParameter()
{

var
asserid=document.entryform.ser_id.options[document.entryform.ser_id.selectedIndex].value;
asserid=asserid.trim();
......
