方法一:使用正则表达式
//方法一:使用正则表达式 function dealBigMoney(money) { if (money === '' || money == null || money === 'undefined') { return; } if (!/^(0|[1-9]\d*)(\.\d+)?$/.test(money)) { return "数据非法"; } money = money * 1.0; if (money === 0) { return "零"; } var unit = "仟佰拾亿仟佰拾万仟佰拾元角分", str = ""; money += "00"; var point = money.indexOf('.'); if (point >= 0) { money = money.substring(0, point) + money.substr(point + 1, 2); } unit = unit.substr(unit.length - money.length); for (var i = 0; i < money.length; i++) { str += '零壹贰叁肆伍陆柒捌玖'.charAt(money.charAt(i)) + unit.charAt(i); } var result = str.replace(/零(仟|佰|拾|角)/g, "零").replace(/(零)+/g, "零").replace(/零(万|亿|元)/g, "$1").replace(/(亿)万/g, "$1$2").replace(/^元零?|零分/g, "").replace(/元$/g, "元整"); return result; }View Code 方法二:常规JavaScript实现
