数字类型钱币转换为大写

做金融网站，免不了将数据转换为钱币的那种中文，今天做一个将算出来的数据在页面显示为大写的中午，还是繁体字那种，这给我纠结的！

好吧，先粘上我的劳动成果吧~

js代码，convertCurrency是一个方法，复制即可。

//小写金额转大写金额
function convertCurrency(currencyDigits) {
    var MAXIMUM_NUMBER = 99999999999.99;
    var CN_ZERO = "零";
    var CN_ONE = "壹";
    var CN_TWO = "贰";
    var CN_THREE = "叁";
    var CN_FOUR = "肆";
    var CN_FIVE = "伍";
    var CN_SIX = "陆";
    var CN_SEVEN = "柒";
    var CN_EIGHT = "捌";
    var CN_NINE = "玖";
    var CN_TEN = "拾";
    var CN_HUNDRED = "佰";
    var CN_THOUSAND = "仟";
    var CN_TEN_THOUSAND = "万";
    var CN_HUNDRED_MILLION = "亿";
    var CN_SYMBOL = "";
    var CN_DOLLAR =(""+currencyDigits).indexOf(".")==-1? "":"元";
    var CN_TEN_CENT = "角";
    var CN_CENT = "分";
    var CN_INTEGER = "";  

    var integral;
    var decimal;
    var outputCharacters;
    var parts;
    var digits, radices, bigRadices, decimals;
    var zeroCount;
    var i, p, d;
    var quotient, modulus;  

    currencyDigits = currencyDigits.toString();   

    currencyDigits = currencyDigits.replace(/,/g, "");
    currencyDigits = currencyDigits.replace(/^0+/, ""); 

    if (Number(currencyDigits) > MAXIMUM_NUMBER) {
      globalUtil.errorMsg(globalErrorMsg[‘100404‘]);
      return "";
    }
    parts = currencyDigits.split(".");
    if (parts.length > 1) {
      integral = parts[0];
      decimal = parts[1];
      decimal = decimal.substr(0, 2);
    }
    else {
      integral = parts[0];
      decimal = "";
    }
    digits = new Array(CN_ZERO, CN_ONE, CN_TWO, CN_THREE, CN_FOUR, CN_FIVE, CN_SIX, CN_SEVEN, CN_EIGHT, CN_NINE);
    radices = new Array("", CN_TEN, CN_HUNDRED, CN_THOUSAND);
    bigRadices = new Array("", CN_TEN_THOUSAND, CN_HUNDRED_MILLION);
    decimals = new Array(CN_TEN_CENT, CN_CENT);
    outputCharacters = "";
    if (Number(integral) > 0) {
      zeroCount = 0;
      for (i = 0; i < integral.length; i++) {
       p = integral.length - i - 1;
       d = integral.substr(i, 1);
       quotient = p / 4;
       modulus = p % 4;
       if (d == "0") {
        zeroCount++;
       }
       else {
        if (zeroCount > 0)
        {
         outputCharacters += digits[0];
        }
        zeroCount = 0;
        outputCharacters += digits[Number(d)] + radices[modulus];
      }
       if (modulus == 0 && zeroCount < 4) {
        outputCharacters += bigRadices[quotient];
      }
      }
      outputCharacters += CN_DOLLAR;
    }
    if (decimal != "") {
      for (i = 0; i < decimal.length; i++) {
       d = decimal.substr(i, 1);
       if (d != "0") {
        outputCharacters += digits[Number(d)] + decimals[i];
       }
      }
    }
    if (outputCharacters == "") {
      outputCharacters = CN_ZERO + CN_DOLLAR;
    }
    if (decimal == "") {
      outputCharacters += CN_INTEGER;
    }
    outputCharacters = CN_SYMBOL + outputCharacters;
    return outputCharacters;
}

贾哥说：恭喜你，你完成了数据转换，马上快到6点了，你可以下班了，别忘记了写日报..............

哈哈，下班啦~

对了，记得自己在网上看的，说支持负数什么的，个人觉得干嘛是负数？不符合实际啊，不可以在文本框做一个onkeyup事件，不允许输入负数。
