Javascript做法
代码演练如下：
可以实现转换为中文大写，及英文大写
View Code
<script src="JS/DecodeNo.js" type="text/javascript"></script> <script type="text/javascript"> function TransCn() { document.getElementById("out").value = ToCn(document.getElementById("Num").value); } function TransEn() { document.getElementById("out").value = ToEn(document.getElementById("Num").value)); } </script> <script type="text/javascript"> function AlertMessage() { alert(document.getElementById("Num").value); } </script> </head> <body> <form action="" method="get" name="mainForm"> <input type="text" name="Num" value="" id="Num" /> <div> <input type="button" name="Eng" value="转换成英文 " onclick="TransEn()" /> <input type="button" name="Chinese" value="转换成中文 " onclick="TransCn()" /> </div> <textarea name="out" cols="90" rows="5" id="out"></textarea> <input type="button" name="alertMessage" value="Alert Message " onclick="AlertMessage();" /> </form> </body>

实例演示如下：
Money mon = new Money();
Response.Write(mon.ConvertToChinese("0")); //这是带 “元整”，如果是整数
Response.Write(mon.ConvertToChinese2("13224324.45")); //不带 元整
