原生JS将数字金额转换成大写

很多借贷公司或者是网上有大笔交易的公司,总是需要在PC端部署一个协议或者是合同,合同所涉及金额,一般正规一点的合同通常是大写人民币,如果你给别人开过收据,你就明白了。
那么到底如何将数据库拿到的数字即时转换成大写呢?

忘记在哪个网站看到的代码了,如果涉及侵权,请私信告知:

      //获取元素内容
       var moneys =$(".money").text();

        function Arabia_To_SimplifiedChinese(Num) {
        for (i = Num.length - 1; i >= 0; i--) {
            Num = Num.replace(",", "")//替换Num中的“,”
            Num = Num.replace(" ", "")//替换Num中的空格
        }

        //验证输入的字符是否为数字
        if (isNaN(Num)) { 
            alert("请检查小写金额是否正确");
            return;
        }

        //字符处理完毕后开始转换,采用前后两部分分别转换(小数点为界限)
        part = String(Num).split(".");

        // 初始化一个字符串
        newchar = "";

        //小数点前进行转化
        for (i = part[0].length - 1; i >= 0; i--) {

            //若数量超过拾亿单位,提示
            if (part[0].length > 10) {
                //alert("位数过大,无法计算");
                return "";
            }


            tmpnewchar = ""
            perchar = part[0].charAt(i);

            switch (perchar) {
                case "0":  tmpnewchar = "零" + tmpnewchar;break;
                case "1": tmpnewchar = "一" + tmpnewchar; break;
                case "2": tmpnewchar = "二" + tmpnewchar; break;
                case "3": tmpnewchar = "三" + tmpnewchar; break;
                case "4": tmpnewchar = "四" + tmpnewchar; break;
                case "5": tmpnewchar = "五" + tmpnewchar; break;
                case "6": tmpnewchar = "六" + tmpnewchar; break;
                case "7": tmpnewchar = "七" + tmpnewchar; break;
                case "8": tmpnewchar = "八" + tmpnewchar; break;
                case "9": tmpnewchar = "九" + tmpnewchar; break;
            }
            switch (part[0].length - i - 1) {
                case 0: tmpnewchar = tmpnewchar; break;
                case 1: if (perchar != 0) tmpnewchar = tmpnewchar + "十"; break;
                case 2: if (perchar != 0) tmpnewchar = tmpnewchar + "百"; break;
                case 3: if (perchar != 0) tmpnewchar = tmpnewchar + "千"; break;
                case 4: tmpnewchar = tmpnewchar + "万"; break;
                case 5: if (perchar != 0) tmpnewchar = tmpnewchar + "十"; break;
                case 6: if (perchar != 0) tmpnewchar = tmpnewchar + "百"; break;
                case 7: if (perchar != 0) tmpnewchar = tmpnewchar + "千"; break;
                case 8: tmpnewchar = tmpnewchar + "亿"; break;
                case 9: tmpnewchar = tmpnewchar + "十"; break;
            }
            newchar = tmpnewchar + newchar;
        }   
        //替换所有无用汉字,直到没有此类无用的数字为止
        while (newchar.search("零零") != -1 || newchar.search("零亿") != -1 || newchar.search("亿万") != -1 || newchar.search("零万") != -1) {
            newchar = newchar.replace("零亿", "亿");
            newchar = newchar.replace("亿万", "亿");
            newchar = newchar.replace("零万", "万");
            newchar = newchar.replace("零零", "零");      
        }
        //替换以“一十”开头的,为“十”
        if (newchar.indexOf("一十") == 0) {
            newchar = newchar.substr(1);
        }
        //替换以“零”结尾的,为“”
        if (newchar.lastIndexOf("零") == newchar.length - 1) {
            newchar = newchar.substr(0, newchar.length - 1);
        }
        return newchar;
    }
    //调用函数,传值
    Arabia_To_SimplifiedChinese(moneys)
    //将函数返回值给元素重新赋值
    $(".money").text(newchar);
