财务web处理的时候经常需要把数字金额转为中文大写，用一个JavaScript客户端脚本来实现自动转换，只需在需要显示大写金额的时候调用该JS函数，而且也可很好的与动态语言相结合，可将最初的小写金额从数据库中读取出来，然后将值输入进JS函数，自动实现人民币金额的大写转换
<script type="text/javascript" language="javascript">
function Arabia_to_Chinese(Num)
{
for(i=Num.length-1;i>=0;i--)
{
Num = Num.replace(",","")//替换tomoney()中的“,”
Num = Num.replace(" ","")//替换tomoney()中的空格
}
Num = Num.replace("￥","")//替换掉可能出现的￥字符
if(isNaN(Num))
{ //验证输入的字符是否为数字
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
part = String(Num).split(".");
newchar = "";
//小数点前进行转化
for(i=part[0].length-1;i>=0;i--)
{
if(part[0].length > 10)
{
alert("位数过大，无法计算");
return "";
}//若数量超过拾亿单位，提示
tmpnewchar = ""
perchar = part[0].charAt(i);

function printp(obj)

</script>S处理部分写好了，那么是如何调用呢？往下看，同样简单：假设要在下面的div中显示大写金额，可以这样调用：
<div><b>已付金额总额(大写):</b><script language="javascript">document.write(Arabia_to_Chinese("3,060.00"));</script></div>也就是把需要转换大写金额的小写数字输入在Arabia_to_Chinese()函数中，然后用javaScript的document.write方法显示在网页上。
