如何使这个jquerycountUP使用格式化的数字？

要使号码有效,您需要删除逗号.你可以replace()这样做:

countTo = $this.attr('data-count').replace(/,/g, '');

我希望实际显示"10,000,000".它应该数到"10,000,000"并输出"10,000,000"

在这种情况下,您可以使用此问题中的函数来格式化输出中的数字step和complete:

$('.counter').each(function() {
  var $this = $(this),
    countTo = $this.attr('data-count').replace(/,/g, '');

  $({
    countNum: $this.text()
  }).animate({
    countNum: countTo
  }, {
    duration: 8000,
    easing: 'linear',
    step: function() {
      $this.text(numberWithCommas(Math.floor(this.countNum)));
    },
    complete: function() {
      $this.text(numberWithCommas(this.countNum));
    }
  });
});

function numberWithCommas(x) {
    return x.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
}

body {
  background-color: #F46A6A;
  color: #fff;
  max-width: 800px;
  margin: 100px auto 0;
  text-align: center;
  display: table;
}

.counter {
  display: table-cell;
  margin: 1.5%;
  font-size: 50px;
  background-color: #FF6F6F;
  width: 200px;
  border-radius: 50%;
  height: 200px;
  vertical-align: middle;
}
