将rmb数字位钱数转化为中文钱数的js函数

效果图:



效果演示:


alert(ChangeRMBToCH("1680760.86"));
function ChangeRMBToCH(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，开始转换，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);
switch(perchar)
{
case "0": tmpnewchar="零" + tmpnewchar ;break;
case "1": tmpnewchar="壹" + tmpnewchar ;break;
case "2": tmpnewchar="贰" + tmpnewchar ;break;
case "3": tmpnewchar="叁" + tmpnewchar ;break;

case "7": tmpnewchar="柒" + tmpnewchar ;break;
case "8": tmpnewchar="捌" + tmpnewchar ;break;
case "9": tmpnewchar="玖" + tmpnewchar ;break;
}
switch(part[0].length-i-1)
{
case 0: tmpnewchar = tmpnewchar +"元" ;break;
case 1: if(perchar!=0)tmpnewchar= tmpnewchar +"拾" ;break;
case 2: if(perchar!=0)tmpnewchar= tmpnewchar +"佰" ;break;
case 3: if(perchar!=0)tmpnewchar= tmpnewchar +"仟" ;break;

case 7: if(perchar!=0)tmpnewchar= tmpnewchar +"仟" ;break;
case 8: tmpnewchar= tmpnewchar +"亿" ;break;
case 9: tmpnewchar= tmpnewchar +"拾" ;break;
}

}
//小数点之后进行转化
if(Num.indexOf(".")!=-1)
{
if(part[1].length > 2)
{
alert("小数点之后只能保留两位,系统将自动截段");
part[1] = part[1].substr(0,2)
}
for(i=0;i
