以下是 JavaScript 实现金额转大写的代码:
function convertCurrency(money) {
var cnNums = new Array(
"零",
"壹",
"贰",
"叁",
"肆",
"伍",
"陆",
"柒",
"捌",
"玖"
);
var cnIntRadice = new Array("", "拾", "佰", "仟");
var cnIntUnits = new Array("", "万", "亿", "兆");
var cnDecUnits = new Array("角", "分", "毫", "厘");
var cnInteger = "整";
var cnIntLast = "元";
var maxNum = 999999999999999.9999;
var integerNum;
var decimalNum;
var chineseStr = "";
var parts;
if (money == "") {
return "";
}
money = parseFloat(money);
if (money >= maxNum) {
return "";
}
if (money == 0) {
chineseStr = cnNums[0] + cnIntLast + cnInteger;
return chineseStr;
}
money = money.toString();
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) {
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;
chineseStr += cnNums[parseInt(n)] + cnIntRadice[m];
}
if (m == 0 && zeroCount < 4) {
chineseStr += cnIntUnits[q];
}
}
chineseStr += cnIntLast;
}
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 == "") {
chineseStr += cnInteger;
}
return chineseStr;
}
使用方法:
var money = 1234.56;
var chineseStr = convertCurrency(money);
console.log(chineseStr);
以下是一种简单的 JavaScript 实现金额转大写的方式:
function convertCurrency(money) {
const cnNums = ['零', '壹', '贰', '叁', '肆', '伍', '陆', '柒', '捌', '玖'];
const cnIntRadice = ['', '拾', '佰', '仟'];
const cnIntUnits = ['', '万', '亿', '兆'];
const cnDecUnits = ['角', '分', '毫', '厘'];
const cnInteger = '整';
const cnIntLast = '元';
let chineseStr = '';
let parts;
if (money == '') {
return '';
}
money = parseFloat(money);
if (isNaN(money) || money >= 1000000000000) {
return '';
}
money = money.toFixed(2);
parts = money.split('.');
let integerNum = parts[0];
let decimalNum = parts[1];
if (parseInt(integerNum) > 0) {
let zeroCount = 0;
let IntLen = integerNum.length;
for (let i = 0; i < IntLen; i++) {
let n = integerNum.substr(i, 1);
let p = IntLen - i - 1;
let q = p / 4;
let m = p % 4;
if (n == '0') {
zeroCount++;
} else {
if (zeroCount > 0) {
chineseStr += cnNums[0];
}
zeroCount = 0;
chineseStr += cnNums[parseInt(n)] + cnIntRadice[m];
}
if (m == 0 && zeroCount < 4) {
chineseStr += cnIntUnits[q];
}
}
chineseStr += cnIntLast;
}
if (decimalNum != '') {
let decLen = decimalNum.length;
for (let i = 0; i < decLen; i++) {
let 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;
}
使用方法和上面的例子相同。
