JS method to convert digital amounts into uppercase RMB Chinese characters

The example in this article describes the JS method of converting digital amounts into uppercase RMB Chinese characters. Share it with everyone for your reference, the details are as follows:

//代码如下所示：
function convertCurrency(money) {
  //汉字的数字
  var cnNums = new Array('零', '壹', '贰', '叁', '肆', '伍', '陆', '柒', '捌', '玖');
  //基本单位
  var cnIntRadice = new Array('', '拾', '佰', '仟');
  //对应整数部分扩展单位
  var cnIntUnits = new Array('', '万', '亿', '兆');
  //对应小数部分单位
  var cnDecUnits = new Array('角', '分', '毫', '厘');
  //整数金额时后面跟的字符
  var cnInteger = '整';
  //整型完以后的单位
  var cnIntLast = '元';
  //最大处理的数字
  var maxNum = 999999999999999.9999;
  //金额整数部分
  var integerNum;
  //金额小数部分
  var decimalNum;
  //输出的中文金额字符串
  var chineseStr = '';
  //分离金额后用的数组，预定义
  var parts;
  if (money == '') { return ''; }
  money = parseFloat(money);
  if (money >= maxNum) {
    //超出最大处理数字
    return '';
  }
  if (money == 0) {
    chineseStr = cnNums[0] + cnIntLast + cnInteger;
    return chineseStr;
  }
  //转换为字符串
  money = money.toString();
  if (money.indexOf('.') == -1) {
    integerNum = money;
    decimalNum = '';
  } else {
    parts = money.split('.');
    integerNum = parts[0];
    decimalNum = parts[1].substr(0, 4);
  }
  //获取整型部分转换
  if (parseInt(integerNum, 10) > 0) {
    var zeroCount = 0;
    var IntLen = integerNum.length;
    for (var i = 0; i < IntLen; i++) {
      var n = integerNum.substr(i, 1);
      var p = IntLen - i - 1;
      var q = p / 4;
      var m = p % 4;
      if (n == &#39;0&#39;) {
        zeroCount++;
      } else {
        if (zeroCount > 0) {
          chineseStr += cnNums[0];
        }
        //归零
        zeroCount = 0;
        chineseStr += cnNums[parseInt(n)] + cnIntRadice[m];
      }
      if (m == 0 && zeroCount < 4) {
        chineseStr += cnIntUnits[q];
      }
    }
    chineseStr += cnIntLast;
  }
  //小数部分
  if (decimalNum != &#39;&#39;) {
    var decLen = decimalNum.length;
    for (var i = 0; i < decLen; i++) {
      var n = decimalNum.substr(i, 1);
      if (n != &#39;0&#39;) {
        chineseStr += cnNums[Number(n)] + cnDecUnits[i];
      }
    }
  }
  if (chineseStr == &#39;&#39;) {
    chineseStr += cnNums[0] + cnIntLast + cnInteger;
  } else if (decimalNum == &#39;&#39;) {
    chineseStr += cnInteger;
  }
  return chineseStr;
}
