The narcissus number refers to an n-digit number ( n≥3), the sum of the nth power of the numbers on each digit is equal to itself.

For example: 1^3 + 5^3+ 3^3 = 153

//判断一个数是否数水仙花数
    var num=prompt('请输入一个数字');
    //得到位数可以计算幂数
    var length=num.length;
    //使用字符串的方法获取每一位数
    var content=num.split("");
    //判断开始输入的数字和计算出来的结果是否相等
    var result=0;
    for(var i=0;i<content.length;i++){
      result+=Math.pow(content[i],length)
    }
    alert(result==num?&#39;这个是水仙花数&#39;:&#39;不是水仙花数&#39;)
