用JavaScript 将数字金额转换为中文大写金额

好的，我可以回答这个问题。以下是将数字金额转换为中文大写金额的JavaScript代码：

function convertToChineseNumeral(amount) {
  const chineseNumeral = ["零", "壹", "贰", "叁", "肆", "伍", "陆", "柒", "捌", "玖"];
  const chineseUnit = ["", "拾", "佰", "仟"];
  const chineseBigUnit = ["", "萬", "亿", "兆"];

  let num = parseFloat(amount);
  let chineseAmount = "";

  if (isNaN(num)) {
    return "";
  }

  let isNegative = num < 0;

  if (isNegative) {
    num = -num;
  }

  let fraction = Math.round((num - Math.floor(num)) * 100);
  if (fraction == 0) {
    chineseAmount += "整";
  } else {
    chineseAmount += chineseNumeral[Math.floor(fraction / 10)] + "角";
    chineseAmount += chineseNumeral[fraction % 10] + "分";
  }

  num = Math.floor(num);

  let unitIndex = 0;
  while (num > 0) {
    let currentUnit = "";
    for (let i = 0; i < 4 && num > 0; i++) {
      let currentNumeral = num % 10;
      if (currentNumeral > 0) {
        currentUnit = chineseUnit[i] + currentUnit;
        currentUnit = chineseNumeral[currentNumeral] + currentUnit;
      } else if (currentUnit != "") {
        currentUnit = chineseNumeral[currentNumeral] + currentUnit;
      }

      num = Math.floor(num / 10);
    }

    if (currentUnit != "") {
      currentUnit += chineseBigUnit[unitIndex];
    }

    chineseAmount = currentUnit + chineseAmount;

    unitIndex++;
  }

  if (chineseAmount == "") {
    chineseAmount = chineseNumeral[0];
  }

  if (isNegative) {
    chineseAmount = "负" + chineseAmount;
  }

  return chineseAmount;
}

console.log(convertToChineseNumeral(123456789.01)); // 壹亿贰仟叁佰肆拾伍萬陆仟柒佰捌拾玖元零壹分
