I computed a number in JavaScript function.

Example:

var price = 1000;
var commission = 200;

var total = price + commission

After I added these two I want to show the total as 1,200 (put , in between 3 digits).

From: http://www.mredkj.com/javascript/numberFormat.html

This functionality is not built into JavaScript, so custom code needs to be used. The following is one way of adding commas to a number, and returning a string.

function addCommas(nStr)
{
    nStr += '';
    x = nStr.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;
}

function addCommas(price) {
    var x = (parseFloat((isNaN(price) ? 0 : price)).toFixed(2)+'').split('.');
    var x3 = x[0].substr(-3);
    for(var i=x[0].length-3; i>0; i=i-3)
        x3 = x[0].substr((i < 3 ? 0 : (i-3)), (i < 3 ? i : 3))+","+x3;
    return x3 + (x.length > 1 ? '.' + x[1] : '');
}

When you do just want an integer value instead of an float with 2 digits, just change the last line to

return x3;
