Question

我用jQuery做了两个简单的计数器。现在，我尝试使这些计数器出现。

我的第一个计数器现在看起来像“ 23000”。但是为了获得更好的概述，我想添加一个点。我已经尝试过将“ 23.000”假装成十进制数字：最多可以用3位数字计数23，但是计数器以“ 0.000”开头，完成后不显示“ 000”。

第二：我的计数器看起来像“ 15.06”，我想用逗号来更改点，例如：“ 15,06”

有人可以帮我吗？

jQuery(document).ready(function () {

    function counter01() {
        $('#01').each(function () {
            var start = $(this).data("start")
            var speed = $(this).data("speed")
            $("#01").prop('end', start).animate({
                end: $(this).data("end")
            }, {
                duration: speed,
                step: function (now) {
                    $(this).text(Math.round(now * 1) / 1);
                }
            });
        });
    }
    
    counter01();

    function counter02() {
        $('#02').each(function () {
            var start = $(this).data("start")
            var speed = $(this).data("speed")

                }
            });
        });

Answer 1

这是经过修改的number_format()函数，可以直接为您进行转换：

function number_format(number, decimals, dec_point) {
  // Strip all characters but numerical ones.
  number = (number + '').replace(/[^0-9+\-Ee.]/g, '');
  var n = !isFinite(+number) ? 0 : +number,
    prec = !isFinite(+decimals) ? 0 : Math.abs(decimals),
    sep = '.',
    dec = (typeof dec_point === 'undefined') ? '.' : dec_point,
    s = '',
    toFixedFix = function(n, prec) {
      var k = Math.pow(10, prec);
      return '' + Math.round(n * k) / k;
    };
  // Fix for IE parseFloat(0.55).toFixed(0) = 0;
  s = (prec ? toFixedFix(n, prec) : '' + Math.round(n)).split('.');
  if (s[0].length > 3) {
    s[0] = s[0].replace(/\B(?=(?:\d{3})+(?!\d))/g, sep);
  }
  if ((s[1] || '').length < prec) {
    s[1] = s[1] || '';
    s[1] += new Array(prec - s[1].length + 1).join('0');
  }
  return s.join(dec);
}

您可以在这里看到它的工作：

function number_format(number, decimals, dec_point) {
  // Strip all characters but numerical ones.
  number = (number + '').replace(/[^0-9+\-Ee.]/g, '');
  var n = !isFinite(+number) ? 0 : +number,
    prec = !isFinite(+decimals) ? 0 : Math.abs(decimals),
    sep = '.',
    dec = (typeof dec_point === 'undefined') ? '.' : dec_point,
    s = '',
    toFixedFix = function(n, prec) {
      var k = Math.pow(10, prec);
      return '' + Math.round(n * k) / k;
    };
  // Fix for IE parseFloat(0.55).toFixed(0) = 0;
  s = (prec ? toFixedFix(n, prec) : '' + Math.round(n)).split('.');
  if (s[0].length > 3) {
    s[0] = s[0].replace(/\B(?=(?:\d{3})+(?!\d))/g, sep);
  }
  if ((s[1] || '').length < prec) {
    s[1] = s[1] || '';
    s[1] += new Array(prec - s[1].length + 1).join('0');
  }
  return s.join(dec);
}
