js金额小写转大写怎么转
js金额小写转大写,js金额小写转大写怎么转教程如下：
输入随机金额
实现结果：生成对应金额的大写
js实现代码如下：
function convertCurrency(currencyDigits) {
// Constants:
var MAXIMUM_NUMBER = 99999999999.99;
// Predefine the radix characters and currency symbols for output:
var CN_ZERO = "闆�";

var CN_HUNDRED = "浣�";
var CN_THOUSAND = "浠�";
var CN_TEN_THOUSAND = "涓�";

var CN_SYMBOL = "浜烘皯甯�";
var CN_DOLLAR = "鍏�";
var CN_TEN_CENT = "瑙�";
var CN_CENT = "鍒�";
