How can I format numbers as money in JavaScript?

I have a form with some simple JavaScript to perform an instant calculation. My problem is that I'm struggling to format it to display correctly with commas and 2 decimal places.

Any help would be very much appreciated. Thank you.

    <label>My Daily Rate is:</label><br />

<input class=poundsBox name=shares id=shares type=text /><br />

<script type=text/javascript>

$(#shares).keyup(function() {

   var val = parseFloat($(this).val());

   // If val is a good float, multiply by 260, else show an error

   val = (val ? val * 260 * 0.88 : Invalid number);

   $(#result).text(val);

})

</script>

You can use standard JS toFixed method

var num = 5.56789;

var n=num.toFixed(2);



//5.57

In order to add commas (to separate 1000's) you can add regexp as follows (where num is a number):

num.toString().replace(/(d)(?=(ddd)+(?!d))/g, $1,)



//100000 => 100,000

//8000 => 8,000

//1000000 => 1,000,000

Complete example:

var value = 1250.223;

var num = '$' + value.toFixed(2).replace(/(d)(?=(ddd)+(?!d))/g, $1,);



//document.write(num) would write value as follows: $1,250.22

Separation character depends on country and locale. For some countries it may need to be .
