displaying javascript result in column

[cheaven]

using a javascript function to determine if a string is all digits or not and return result based off the decision. if it is all digits, mask all digits except the first two, if not all digits just return the string.

these are the snippets however i am not seeing anything returned in the column

<script >


var start = function RenderRC(CodeOwner) {

        var Rcode = CodeOwner.toString();

        var pattern = new RegExp("^\d{2,}$ ");

        if (Rcode.match(pattern)) {

            if (Rcode.length > 2)
             {
                var newcode = Rcode.substr(0, 2) + Array(Rcode.length - 2 + 1).join("*");
                return newcode;
            }

        }
          else 
        {
               return Rcode; 
        }
        
    };

</script>

 <ext:RecordField Name="CodeOwner" />


 <ext:Column Header="<%$ Resources:Text, CodeOwner %>"DataIndex="CodeOwner" Width="110" >
                <Renderer Fn ="start" />
                </ext:Column>

What does the HTML look like?

<script type = "text/javascript"> 

function a(str) {
if (/\D/gi.test(str)) {
return str;  // non-digits found
}
var len = str.length;
var newstr = str.substring(0,2);
var rest = str.substring(2);
rest = rest.replace(/\d/g,"*");
newstr += rest;
return newstr;
}

alert  (a("1234567"));

</script>

No,the alert is simply for test/demonstration purposes. As felgall says, we need to see the (relevant) HTML code before we can go any further.
