Auto Comma using javascript

Hi Friends,
I want to display numbers as comma separated string
(like we show amount 12,34,675.67)

I have a javascript function, which I call on onkeyup event of a textbox.
Here is that function :

JavaScript

function Comma(Num) 
{
     Num += '';
     Num = Num.replace(/,/g, '');

      x = Num.split('.');
      x1 = x[0];
      x2 = x.length > 1 ? '.' + x[1] : '';
      var rgx = /(\d+)(\d{3})/;
      while (rgx.test(x1))
         x1 = x1.replace(rgx, '$1' + ',' + '$2');
      
      return x1 + x2;
}

This function gives me the amount as
123,456,984.00

Now, if I repoen my Voucher, I have formatted the textbox for amount using

C#

.ToString("N")

which shows me the value as
12,34,67,567.00

AS you can see, there is difference in comma placings of these two functions.

How can I achieve the same format for amount ??
And it will be a lot better, if the value is rounded by two digits after decimal point.

Any help is appreciated.

Thanks,
Lok..

Why not use one of the many existing Masked Edit controls?

Thanks for the replies..
But my client is not happy with the behaviour of MaskedEditExtender.
It shows commas and dot while typing, which he thinks is quit annoynig.

Could you please help me with what I have (i.e. that script function) ???

finally got it working guys..

function Comma(Num) {
var number = Num;
if (number.length > 3) {
Num += '';
Num = Num.replace(/,/g, '');
x = Num.split('.');
x1 = x[0];
x2 = x.length > 1 ? '.' + x[1] : '';

var rgx = /(\d+)(\d{3})/;
var x3;
x1 = x1.replace(rgx, '$1' + ',' + '$2');

if (x1.length > 3) {
x3 = x1.split(',');
rgx = /(\d+)(\d{2})/;
while (rgx.test(x3[0]))
x3[0] = x3[0].replace(rgx, '$1' + ',' + '$2');
}
if ((x1.length == 3 && x2.indexOf(".") != -1) || (x1.length == 2 && x2.indexOf(".") != -1) || (x1.length == 1 && x2.indexOf(".") != -1))
return x1 + x2;
else
return x3[0] + ',' + x3[1] + x2;
}
else {
return Num;
}
}
