要用javascript做的，

<script>
var str="10000000";
var newStr=""
for(var i=str.length,j=0;i>0;i-=3,j++)
subs[j]=str.substring(i,i-3)
subs.reverse()
for(var i=0;i<subs.length;i++)
newStr+=(i==subs.length-1)?subs[i]:subs[i]+","
alert(str+"\n"+newStr)
</script>

[shyslysky]

<script>
var str="10000000";
var counts=str.length/3
var subs=new Array()
var newStr=""
for(var i=str.length,j=0;i>0;i-=3,j++)
subs[j]=str.substring(i,i-3)
subs.reverse()
for(var i=0;i<subs.length;i++)
newStr+=(i==subs.length-1)?subs[i]:subs[i]+","
alert(str+"\n"+newStr)
</script>

//给数字字符串加上","隔开，如"1000000"变为"1,000,000"
function addCommaToNumber(numberStr){
var str=numberStr;
var subs=new Array()
var newStr=""
for(var i=str.length,j=0;i>0;i-=3,j++)
subs[j]=str.substring(i,i-3)
subs.reverse()
for(var i=0;i<subs.length;i++)
newStr+=(i==subs.length-1)?subs[i]:subs[i]+","
return newStr
}
alert(addCommaToNumber("1000000000000"))
