Question

我正在尝试根据一系列货币格式的数字创建一个小计，但我正在努力将数字转换回整数以便可以添加它们。以下是我的尝试：

＆＃13;

$(function() {
  var totals = $('.price');

  var sum = 0;
  for (var i = 0; i < totals.length; i++) {
    //strip out dollar signs and commas
    $(totals[i].text()).replace(/[^\d.]/g, '');

    //convert string to integer
    var ct = parseFloat($(totals[i].text()));
    sum += ct;
  }

  console.log(sum);
});

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="price">$195,000.20</div>
<div class="price">$21,404.00</div>
<div class="price">$7,000.00</div>
<div class="price">$450.00</div>

＆＃13;

Answer 1

replace()不会修改传入的字符串（无论如何它都不能在这里，因为它是函数的结果）。它只是返回修改后的值。

保存replace()的结果，并根据该结果汇总：

$(function() {
  var totals = $('.price');

  var sum = 0;
  for (var i = 0; i < totals.length; i++) {
    //strip out dollar signs and commas
    var v = $(totals[i]).text().replace(/[^\d.]/g, '');

    //convert string to integer
    var ct = parseFloat(v);
    sum += ct;
  }

  console.log(sum);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="price">$195,000.20</div>
<div class="price">$21,404.00</div>
<div class="price">$7,000.00</div>
<div class="price">$450.00</div>

另外：请注意拼写错误 - 您需要$(totals[i]).text()，而不是$(totals[i].text())
