將數(shù)字轉(zhuǎn)換成大寫的人民幣表達(dá)式的js函數(shù)

    將數(shù)字轉(zhuǎn)換成大寫的人民幣，方法有很多，本例介紹的是使用js來完成的，看看下面的實(shí)現(xiàn)代碼
    function changeNumMoneyToChinese(money) {
    var cnNums = new Array("零", "壹", "貳", "叁", "肆", "伍", "陸", "柒", "捌", "玖"); //漢字的數(shù)字
    var cnIntRadice = new Array("", "拾", "佰", "仟"); //基本單位
    var cnIntUnits = new Array("", "萬", "億", "兆"); //對(duì)應(yīng)整數(shù)部分?jǐn)U展單位
    var cnDecUnits = new Array("角", "分", "毫", "厘"); //對(duì)應(yīng)小數(shù)部分單位
    var cnInteger = "整"; //整數(shù)金額時(shí)后面跟的字符
    var cnIntLast = "元"; //整型完以后的單位
    var maxNum = 999999999999999.9999; //最大處理的數(shù)字
    var IntegerNum; //金額整數(shù)部分
    var DecimalNum; //金額小數(shù)部分
    var ChineseStr = ""; //輸出的中文金額字符串
    var parts; //分離金額后用的數(shù)組，預(yù)定義
    if (money == "") {
    return "";
    }
    money = parseFloat(money);
    if (money >= maxNum) {
    alert('超出最大處理數(shù)字');
    return "";
    }
    if (money == 0) {
    ChineseStr = cnNums[0] + cnIntLast + cnInteger;
    return ChineseStr;
    }
    money = money.toString(); //轉(zhuǎn)換為字符串
    if (money.indexOf(".") == -1) {
    IntegerNum = money;
    DecimalNum = '';
    } else {
    parts = money.split(".");
    IntegerNum = parts[0];
    DecimalNum = parts[1].substr(0, 4);
    }
    if (parseInt(IntegerNum, 10) > 0) { //獲取整型部分轉(zhuǎn)換
    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 == "0") {
    zeroCount++;
    } else {
    if (zeroCount > 0) {
    ChineseStr += cnNums[0];
    }
    zeroCount = 0; //歸零
    ChineseStr += cnNums[parseInt(n)] + cnIntRadice[m];
    }
    if (m == 0 && zeroCount < 4) {
    ChineseStr += cnIntUnits[q];
    }
    }
    ChineseStr += cnIntLast;
    //整型部分處理完畢
    }
    if (DecimalNum != '') { //小數(shù)部分
    var decLen = DecimalNum.length;
    for (var i = 0; i < decLen; i++) {
    var n = DecimalNum.substr(i, 1);
    if (n != '0') {
    ChineseStr += cnNums[Number(n)] + cnDecUnits[i];
    }
    }
    }
    if (ChineseStr == '') {
    ChineseStr += cnNums[0] + cnIntLast + cnInteger;
    } else if (DecimalNum == '') {
    ChineseStr += cnInteger;
    }
    return ChineseStr;
    }
