将逗号添加到JavaScript输出

Question

我正在使用以下脚本以一定间隔向上计数,它完美地运行.但是,我希望用逗号(56,181,995而不是56181995)格式化数字.

var START_DATE = new Date("July 27, 2010 13:30:00"); // put in the starting date here
var INTERVAL = 1; // in seconds
var INCREMENT = 2; // increase per tick
var START_VALUE = 101; // initial value when it's the start date
var count = 0;

window.onload = function()
{
var msInterval = INTERVAL * 1000;
var now = new Date();
count = parseInt((now - START_DATE)/msInterval) * INCREMENT + START_VALUE;
document.getElementById('counter').innerHTML = count;
setInterval("count += INCREMENT; document.getElementById('counter').innerHTML = count;", msInterval);
}

我以为我在这里找到了答案,但是我无法让它起作用:

Answer 1

(1234567890).toLocaleString();

Answer 2

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

集成:

var msInterval = INTERVAL * 1000;
var now = new Date();
count = parseInt((now - START_DATE)/msInterval) * INCREMENT + START_VALUE;
document.getElementById('counter').innerHTML = addCommas(count);
setInterval("count += INCREMENT; document.getElementById('counter').innerHTML = addCommas(count);", msInterval);
