js去除金额格式化

function removeCurrencyFormat(amountStr) {
    // 移除所有非数字和非小数点的字符
    let cleanedAmount = amountStr.replace(/[^0-9.-]+/g, "");
    // 转换为数字
    return parseFloat(cleanedAmount);
}

// 使用示例
let formattedAmount = "$1,234.56";
let originalAmount = removeCurrencyFormat(formattedAmount);
console.log(originalAmount); // 输出: 1234.56

function parseCurrency(currencyStr, locale = 'en-US') {
    const formatter = new Intl.NumberFormat(locale);
    const parts = formatter.formatToParts(1234.56);
    const groupSeparator = parts.find(p => p.type === 'group').value;
    const decimalSeparator = parts.find(p => p.type === 'decimal').value;

    // 移除货币符号、千分位分隔符和小数点
    let cleanedAmount = currencyStr
        .replace(/[^0-9.-]+/g, '')
        .replace(new RegExp('\\' + groupSeparator, 'g'), '')
        .replace(new RegExp('\\' + decimalSeparator), '.');

    return parseFloat(cleanedAmount);
}

// 使用示例
let formattedAmount = "1.234,56 €"; // 注意：这是欧洲常见的格式，逗号作为小数点，点作为千分位分隔符
let originalAmount = parseCurrency(formattedAmount, 'de-DE');
console.log(originalAmount); // 输出: 1234.56
