JavaScript 金额大小写

    大写转小写,这个需求不常见,仅支持“亿" 以下:

    function cacl(num) {
        if( "" == num ){
            return 0;
        }
        num = num.replace(/[零壹贰叁肆伍陆柒捌玖]/g, function($1) {
                return "零壹贰叁肆伍陆柒捌玖".indexOf($1)
        });
        num = num.replace(/[分角拾佰仟]/g, function($1) {
                return "*" + Math.pow(10, "分角 拾佰仟".indexOf($1) - 2) + "+"
        });
        num = num.replace(/正/, "0").replace(/整/, "0").replace(/元/, "+");
        num = num.replace(/^\*|\+$/g, "").replace(/\+{2,}/g, "+");
        console.log(num);
        return eval(num);
    }
    
    function Amount2Number(num){
        // 不对亿处理
        num.replace("亿","");
        // 万 拆分处理
        if( num.indexOf("万") > 0)
        {
            var pieces = num.split("万");
            return cacl(pieces[0])* 10000 + cacl(pieces[1]);
    
        }
        return cacl(num);
    
    }
    
    

    小写转大写,这段是别人写好的。
