javascript - 未使用 .toLocaleString 获取所有货币符号

Question

我正在尝试获取存储在 XML 文件中的货币列表的符号。

我的 XML 文件如下所示:

这是负责获取符号的代码:

function getCurrencySymbol(currencyCode) {
    return (0)
        .toLocaleString('en', {style: 'currency', currency: currencyCode})
        .replace(/[0,.]/g, '')
        .trim();
}

function setSelectedCurrency(currencyCode, shouldInsertQuery) {
    if (typeof shouldInsertQuery !== 'boolean') {
        shouldInsertQuery = true;
    }

    selectedCurrency = currencyCode;
    var symbol = getCurrencySymbol(currencyCode);
    $('#currency-selector').text(currencyCode + ' ' + symbol);
    window.localStorage.setItem('bonocar-last_selected-currency', currencyCode);
    if (shouldInsertQuery) {
        insertParam('curr', currencyCode);
    }
}

function filterCurrencies() {
    var inputValue = $('#currency-selector-filter').val().trim();
    if (inputValue === '') {
        showAvailableCurrencies(currencies);
    } else {
        const fc = currencies.filter(function(c) {
            return c.toLowerCase().indexOf(inputValue.toLowerCase()) !== -1;
        });
        showAvailableCurrencies(fc);
    }
}

function showAvailableCurrencies(availableCurrencies) {
    var currencyItemsDropdown = $('.currency-selector-dropdown-ul');
    var currencyElementItems = document.createDocumentFragment();

    availableCurrencies.forEach(function(c) {
        var content = c + ' ' + getCurrencySymbol(c);
        var item = document.createElement('li');
        item.textContent = content;
        item.onclick = function() {
            setSelectedCurrency(c);
        }
        currencyElementItems.append(item);
    });

    currencyItemsDropdown.html('');
    currencyItemsDropdown.append(currencyElementItems);
}

当我查看 DOM 时，我注意到只有几种货币被转换:

我做错了什么？

Answer 1

经过一番研究并尝试不同的解决方案后，我不得不同意这个答案 https://stackoverflow.com/a/53749034并建议使用包含每种货币已知符号 map 的库。
