可以通过缩放来进行分到元的转换，同时使用正则对处理后的数字进行千分位格式化
num=num*0.01//分到元
num+=''//转成字符串
reg=num.indexOf('.') >-1 ? /(\d{1,3})(?=(?:\d{3})+\.)/g : /(\d{1,3})(?=(?:\d{3})+$)/g//确定使用有哪个正则
num=num.replace(reg, '$1,')//千分位格式化
经过上述4步，即可完成分到元的转换，并且有千分位的格式化
<script type="text/javascript">function money(mon){
var smon = Math.round(mon*100)
var splot = smon % 100

var ch_key = new Array('零','壹','贰','叁','肆','伍','陆','柒','捌','玫')
var dan_key = new Array('拾','佰','仟','万','拾万','百万','仟万','亿')
var str_num = zheng+''
var len = str_num.length
var slen = len-1
var rs = ''
for(var i = 0i<leni++){
var ch = parseInt(str_num.charAt(i))

百度一下这种写好的js很多 随便选个就可以我帮你搜了个function Arabia_to_Chinese(Num){
for(i=Num.length-1i>=0i--)
{
Num = Num.replace(",","")
Num = Num.replace(" ","")
}
Num = Num.replace("￥","")
if(isNaN(Num)) {
alert("请检查小写金额是否正确")
return
}
part = String(Num).split(".")
newchar = ""
for(i=part[0].length-1i>=0i--){
if(part[0].length >10){ alert("位数过大，无法计算")return ""}
tmpnewchar = ""
perchar = part[0].charAt(i)
switch(perchar){
case "0": tmpnewchar="零" + tmpnewchar break

}
if(i==0)tmpnewchar =tmpnewchar + "角"
if(i==1)tmpnewchar = tmpnewchar + "分"
newchar = newchar + tmpnewchar
}
}
while(newchar.search("零零") != -1)
newchar = newchar.replace("零零", "零")
newchar = newchar.replace("零亿", "亿")
newchar = newchar.replace("亿万", "亿")

看了下没什么大问题
