Question

我有这个Javascript

<script>
var START_DATE = new Date("February 21, 2018 00:00:00"); // put in the 
starting date here
var INTERVAL = 1; // in seconds
var INCREMENT = 6720; // increase per tick
var START_VALUE = 17419171608; // 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);
}
</script>

我试图用逗号分隔上面代码中的数千个但我无法这样做。

我尝试了here的说明，但是我无法用逗号分隔数千个。

非常感谢任何帮助。感谢。

Answer 1

您可以尝试在＆＃34; count＆＃34;上使用Number.prototype.toLocaleString（）函数。变量。将根据区域设置打印该编号，因此对于EN，它将具有预期的逗号。

var count = 10000000;    
console.log (count.toLocaleString());

检查出来：How to print a number with commas as thousands separators in JavaScript

解析负数，大数和浮点数有很好的功能。

您可以尝试在执行此操作后输出您的计数：

const numberWithCommas = (x) => {
  var parts = x.toString().split(".");
  parts[0] = parts[0].replace(/\B(?=(\d{3})+(?!\d))/g, ",");
  return parts.join(".");
}
