数字转中文,大写,金额

      最近，又发现了另外一种数字转中文,大写,金额的方法，觉得会比之前找到的跟合适一点：npm安装包地址：（在这里，会有更加详细的使用介绍。而我就只是测了其中一种。。。。。。）

简介：Nzh适用于开发过程中需要将数字转换为中文的场景 以字符串的方式转换,解决超大数及浮点数等问题,请自行对原数据进行四舍五入等操作.

1.首先在项目中安装依赖包：npm install nzh

附上nzh.js的源代码：

/* 
待优化点
1.小数点拆分计算 1
2.代码简洁化 1
3.亿亿转万万亿 1
4.转金额规则规范化 参考 =lqGf7GrSnMPYvmrb4qMP_yS9k7aATfDidjsAC3eHv7Sxm76_hbamjuLaZH_g74n0Mr-a9CwIy6ekOIEK3Lt-G_待补充点
1.中文数字转阿拉伯数字 1
2.港台地区支持 1
3.自定义转换 1
4.科学记数法字符串支持*/

}));

2.其实这是自己在做小测试的时候，使用nzh的，在安装完依赖包之后，自己将nzh.js文件直接引入页面中，

<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>Title</title><script type="text/javascript" src="js/jquery-1.11.3.js"></script><script type="text/javascript" src="js/nzh.js"></script>
</head>
<body>
<div style="margin: 100px 200px;"><p>输入金额</p><input type="text" id="low"></br><input type="button" value="转为大写金额" id="btn" onclick="trans()"/><div id="all"></div>
</div>
<script type="text/javascript">jQuery(function(){jQuery("#btn").click(function () {var text = jQuery("#low").val();var nzhcn = Nzh;jQuery("#all").html(nzhcn.toMoney(text));});});
</script>
</body>
</html>

效果就是：

3.自己觉得该方法会比之前的两种方法更好一点，不过还是要看具体情况，选择使用哪一种。
