javascript字符串拆分成单个字符相加和不超过10，求最终值

<script type="text/javascript"> var str = "19871229"; var count = 0; for(var i = 0 ; i < str.length ; i++) count += parseInt(str.charAt(i)); alert (getResult(count)); function getResult(x) { var a = Math.floor(x/10); var b = x%10; if(a+b > 10) return getResult(a+b); else return (a+b); } </script>

复制代码 代码如下:

function s(str:String) {
var j:Number = str.length;
for (var i:Number = 0; j>1; i++) {
var Num:Number = Number(str.charAt(0))+Number(str.charAt(1));
str = Num+str.slice(2, str.length);
j = str.length;
}
return str;
}
trace(s("19850401"));

复制代码 代码如下:
