将阿拉伯数字转换成中文大写的函数(javascript)

function Chinese(num) //将阿拉伯数字翻译成中文的大写数字
{
if(!/^/d*(/./d*)?$/.test(num)){alert("Number is wrong!"); return "Number is wrong!";}
var AA = new Array("零","壹","贰","叁","肆","伍","陆","柒","捌","玖");
var BB = new Array("","拾","佰","仟","萬","億","点","");

var a = (""+ num).replace(/(^0*)/g, "").split("."), k = 0, re = "";

for(var i=a[0].length-1; i>=0; i--)
{
switch(k)
{
case 0 : re = BB[7] + re; break;
case 4 : if(!new RegExp("0{4}//d{"+ (a[0].length-i-1) +"}$").test(a[0]))

case 8 : re = BB[5] + re; BB[7] = BB[5]; k = 0; break;
}
if(k%4 == 2 && a[0].charAt(i+2) != 0 && a[0].charAt(i+1) == 0) re = AA[0] + re;

功能：将阿拉伯数字(小写)转化成中文(大写）

参数：Num为字符型,小数点之后保留两位,例：Arabia_to_Chinese("1234.06")
说明：1.目前本转换仅支持到 拾亿（元） 位，金额单位为元，不能为万元，最小单位为分
2.不支持负数
