拆四位数字

<script>
   var n = 2301
   while(n>0)
       console.log(n%10+'');
       n = parseInt(n/10)
   
</script>

时间单位换算

<script>
        var time = 123456789;
        var day =parseInt(time / (24*60*60));
        console.log(day+'天');
        var house = parseInt((time % (24*60*60))/(60*60));
        console.log(house+'小时');
        var fenzh = parseInt((time % (24*60*60))%(60*60)/60);
        console.log(fenzh+'分钟'); 
        var miao = parseInt((time % (24*60*60))%(60*60)%60);
        console.log(miao+'秒');
</script>

求10の阶乘

var n =1,sum =1
  while(n<=10)
      sum *= n;
      n++;    
  
console.log(sum);

查找三次自幂数

var n = 153
while(n<=999)
    a = parseInt(n%10)
    b = parseInt((n/10)%10)
    c = parseInt(n/100)
    if(a**3 + b**3 +c**3 == n)
        console.log(n+' ');
    
    n++;
