add commas to a number in jQuery

Question

I have these numbers

10999 and 8094 and 456

And all i want to do is add a comma in the right place if it needs it so it looks like this

10,999 and 8,094 and 456

These are all within a p tag like this <p class="points">10999</p> etc.

Can it be done?

I've attempted it here with the help of other posts http://jsfiddle.net/pdWTU/1/ but can't seem to get it to work

Thanks

Jamie

UPDATE

Messed around a bit and managed to figure it out here http://jsfiddle.net/W5jwY/1/

Going to look at the new Globalization plugin for a better way of doing it

Thanks

Answer 1

Works on all browsers, this is all you need.

  function commaSeparateNumber(val){
    while (/(\d+)(\d{3})/.test(val.toString())){
      val = val.toString().replace(/(\d+)(\d{3})/, '$1'+','+'$2');
    }
    return val;
  }

Wrote this to be compact, and to the point, thanks to regex. This is straight JS, but you can use it in your jQuery like so:

$('#elementID').html(commaSeparateNumber(1234567890));

or

$('#inputID').val(commaSeparateNumber(1234567890));
