主要函数代码:
复制代码 代码如下:

function Chinese(num)
{
if(!/^\d*(\.\d*)?$/.test(num))
{
alert("你输入的不是数字,请重新输入!");
return false;
}
var AA = new Array("零","壹","贰","叁","肆","伍","陆","柒","捌","玖");
var BB = new Array("","拾","佰","仟","万","亿","点","");
var a = (""+ num).replace(/(^0*)/g, "").split("."), k = 0, re = "";
for(var i=a[0].length-1; i>=0; i--)
{
switch(k)
{
case 0 :
re = BB[7] + re;
break;
case 4 :
if(!new RegExp("0{4}\\d{"+ (a[0].length-i-1) +"}$").test(a[0]))
re = BB[4] + re;
break;
case 8 :
re = BB[5] + re;
BB[7] = BB[5];
k = 0;
break;
}
if(k%4 == 2 && a[0].charAt(i)=="0" && a[0].charAt(i+2) != "0") re = AA[0] + re;
if(a[0].charAt(i) != 0) re = AA[a[0].charAt(i)] + BB[k%4] + re;
k++;
}
if(a.length>1) {
re += BB[6];
for(var i=0; i}
return re;
}

使用方法:
复制代码 代码如下:

function TrunToChina()
{
var num= 123456789;
  alert(Chinese(num));
}
TrunToChina();
