如何使用 JavaScript 在 Shopify 上格式化货币

Question

我在 Shopify 上使用 JavaScript https://gist.github.com/stewartknapman/8d8733ea58d2314c373e94114472d44c

找到了这个 Gist for money formatting

我把它放在我的购物车页面，当我尝试时：

Shopify.formatMoney(2000, '$')

我明白了：

cart:2166 Uncaught TypeError: Cannot read property '1' of null
    at Object.Shopify.formatMoney (cart:2166)
    at <anonymous>:1:9

this is at switch(formatString.match(placeholderRegex)[1]) {

我希望得到 20.00 美元

你知道问题出在哪里吗？

要点内容

var Shopify = Shopify || {};
// ---------------------------------------------------------------------------
// Money format handler
// ---------------------------------------------------------------------------
Shopify.money_format = "${{amount}}";
Shopify.formatMoney = function(cents, format) {
  if (typeof cents == 'string') { cents = cents.replace('.',''); }
  var value = '';
  var placeholderRegex = /\{\{\s*(\w+)\s*\}\}/;
  var formatString = (format || this.money_format);

  function defaultOption(opt, def) {
     return (typeof opt == 'undefined' ? def : opt);
  }

  function formatWithDelimiters(number, precision, thousands, decimal) {
    precision = defaultOption(precision, 2);
    thousands = defaultOption(thousands, ',');
    decimal   = defaultOption(decimal, '.');

    if (isNaN(number) || number == null) { return 0; }

    number = (number/100.0).toFixed(precision);

    var parts   = number.split('.'),
        dollars = parts[0].replace(/(\d)(?=(\d\d\d)+(?!\d))/g, '' + thousands),
        cents   = parts[1] ? (decimal + parts[1]) : '';

    return dollars + cents;
  }

  switch(formatString.match(placeholderRegex)[1]) {
    case 'amount':
      value = formatWithDelimiters(cents, 2);
      break;
    case 'amount_no_decimals':
      value = formatWithDelimiters(cents, 0);
      break;
    case 'amount_with_comma_separator':
      value = formatWithDelimiters(cents, 2, '.', ',');
      break;
    case 'amount_no_decimals_with_comma_separator':
      value = formatWithDelimiters(cents, 0, '.', ',');
      break;
  }

  return formatString.replace(placeholderRegex, value);
};

我在我的主题中找到了 formatMoney 函数，我可以调用它并且它起作用了。

pipelineVendor.themeCurrency.formatMoney(2000);
result: .00
