javascript - 将逗号添加到 setinterval 计数器值

Question

标题可能不对，抱歉。

我正在尝试为一个网站制作一个实时计数器，它的想法是显示一个每秒都在增加的假数字。到目前为止我有这个

var START_DATE = new Date("November 27, 2014 13:30"); // put in the starting date here
var INTERVAL = 1; // in seconds
var INCREMENT = 2; // increase per tick
var START_VALUE = 901; // initial value when it's the start date
var count = 0; //finally this shit is working

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);
}
   

<div id="counter"></div>

它显示每秒增加的数字，如“24350919”，我想将其转换为 24,350,919。我尝试使用 parseFloat，但我无法让它工作。

有人可以帮助我吗？谢谢!

编辑:-

var START_DATE = new Date("November 27, 2014 13:30"); // put in the starting date here
var INTERVAL = 1; // in seconds
var INCREMENT = 2; // increase per tick
var START_VALUE = 901; // initial value when it's the start date
var count = 0; //finally this shit is working


window.onload = function() {
  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);
}

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

<div id="counter"></div>

您可以像这样尝试使用 toLocaleString():

var n = 24350919
n.toLocaleString()

在你的情况下它就像

setInterval("count += INCREMENT; document.getElementById('counter').innerHTML =
         count;", msInterval.toLocaleString());
