js数字转汉字

以下是将数字转换为汉字的 JavaScript 函数：

function numberToChinese(num) {
  var digits = '零一二三四五六七八九';
  var units = '个十百千万亿';
  var result = '';
  var numStr = num.toString();

  for (var i = 0; i < numStr.length; i++) {
    var digit = parseInt(numStr.charAt(i));
    var unit = units.charAt(numStr.length - i - 1);

    if (digit !== 0) {
      result += digits.charAt(digit) + unit;
    } else if (unit === '亿' || unit === '万' || numStr.length === 1) {
      result += digits.charAt(digit);
    }
  }

  return result;
}

使用示例：

console.log(numberToChinese(123)); // 一百二十三
console.log(numberToChinese(10000)); // 一万
console.log(numberToChinese(100000000)); // 一亿

js 数字转汉字

以下是 JavaScript 实现将数字转换为汉字的代码：

function numberToChinese(num) {
  if (isNaN(num)) return "";
  const units = ["零", "一", "二", "三", "四", "五", "六", "七", "八", "九"];
  const unitChars = ["", "十", "百", "千"];
  const bigUnitChars = ["", "万", "亿", "兆"];
  let result = "";
  let numStr = num.toString();
  let len = numStr.length;
  let zeroFlag = true;
  let pos = 0;
  while (len > 0) {
    let cur = parseInt(numStr.charAt(pos));
    let curChar = units[cur];
    let unitChar = unitChars[len - 1];
    if (cur === 0) {
      if (!zeroFlag) {
        result += curChar;
        zeroFlag = true;
      }
    } else {
      result += curChar + unitChar;
      zeroFlag = false;
    }
    pos++;
    len--;
    if (len === 0 && pos < numStr.length) {
      let bigUnitChar = bigUnitChars[Math.ceil(pos / 4)];
      result += bigUnitChar;
      len = numStr.length - pos;
    }
  }
  return result;
}

使用方法：

console.log(numberToChinese(123456789)); // 输出：一亿二千三百四十五万六千七百八十九

js 阿拉伯数字转换中文数字

可以使用以下代码将阿拉伯数字转换为中文数字：

function numberToChinese(num) {
  var cnNums = ["零", "一", "二", "三", "四", "五", "六", "七", "八", "九"];
  var cnIntUnits = ["", "万", "亿", "万亿"];
  var cnIntRadice = ["", "十", "百", "千"];
  var cnDecUnits = ["角", "分", "毫", "厘"];
  var cnIntLast = "元";
  var maxNum = 999999999999999.9999;
  var integerNum;
  var chineseStr = "";
  var parts;

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

  num = parseFloat(num);
  if (num >= maxNum) {
    return "";
  }
  if (isNaN(num)) {
    return "";
  }

  integerNum = Math.floor(num);
  if (integerNum === 0) {
    chineseStr = cnNums[0] + cnIntLast;
    return chineseStr;
  }

  var intStr = integerNum.toString();
  var len = intStr.length;
  var i, j;
  if (len > 15) {
    return "";
  }

  parts = new Array(len);
  for (i = 0; i < len; i++) {
    parts[i] = parseInt(intStr.charAt(i), 10);
  }

  var partLen = Math.ceil(len / 4);
  var partChinese;
  for (i = 0; i < partLen; i++) {
    partChinese = "";
    for (j = 0; j < 4; j++) {
      if (parts[i * 4 + j] === 0) {
        continue;
      }
      partChinese += cnNums[parts[i * 4 + j]] + cnIntRadice[4 - j - 1];
    }
    partChinese += cnIntUnits[partLen - i - 1];
    chineseStr += partChinese;
  }

  if (num.toString().indexOf(".") !== -1) {
    var decNum = num.toString().split(".")[1];
    var decLen = decNum.length;
    for (i = 0; i < decLen; i++) {
      if (i > 3) {
        break;
      }
      chineseStr += cnNums[parseInt(decNum.charAt(i), 10)] + cnDecUnits[i];
    }
  }

  if (chineseStr === "") {
    chineseStr += cnNums[0] + cnIntLast;
  } else if (num < 1) {
    chineseStr = cnNums[0] + chineseStr;
  }

  return chineseStr;
}

使用示例：

console.log(numberToChinese(123456789)); // 一亿二千三百四十五万六千七百八十九元
console.log(numberToChinese(100000001)); // 一亿零一元
console.log(numberToChinese(0.5)); // 五角
