JS conversion amount capitalization method

//代码如下所示：
function menoyToUppercase(money) {
    var cnNums = new Array('零', '壹', '贰', '叁', '肆', '伍', '陆', '柒', '捌', '玖');	 //汉字的数字
    var cnIntRadice = new Array('', '拾', '佰', '仟'); //基本单位
    var cnIntUnits = new Array('', '万', '亿', '兆');  //对应整数部分扩展单位
    var cnDecUnits = new Array('角', '分', '毫', '厘'); //对应小数部分单位
    var cnInteger = '整';	//整数金额时后面跟的字符
    var cnIntLast = '元';	//整数完以后的单位
    //最大处理的数字
    var maxNum = 999999999999999.9999;
    var integerNum;	 //金额整数部分
    var decimalNum;	 //金额小数部分
    //输出的中文金额字符串
    var chineseStr = '';
    var parts;		//分离金额后用的数组，预定义
    if (money == '') { return ''; }

    money = parseFloat(money);
    if (money >= maxNum) {
        //超出最大处理数字
        return '超出最大处理数字';
    }
    if (money == 0) {
        chineseStr = cnNums[0] + cnIntLast + cnInteger;
        return chineseStr;
    }
    //四舍五入保留两位小数,转换为字符串
    money = Math.round(money * 100).toString();
    integerNum = money.substr(0,money.length-2);
    decimalNum = money.substr(money.length-2);
    //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 == '0') {
                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 != '') {
        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 == '' || /^0*$/.test(decimalNum)) {
        chineseStr += cnInteger;
    }
    return chineseStr;
}

Just call this method directly

Take a chestnut:

let money = 100;  //100元、200元。。。。
let chineseStr = menoyToUppercase(money);
$('#id').val(chineseStr);

At this time, the value in the chineseStr variable is already uppercase (floating-point decimals can also be converted)

Of course, you can also add a function to determine whether the user input is a number or a string.
