我有一个数学网站http://finitehelp.com,教授学生有限数学.我认为包含一个计算器会很酷,所以我在Javascript中为组合和排列做了一个.实时计算器位于http://finitehelp.com/finite-calculator.html.我对Javascript几乎一无所知,并且冒昧地猜测有一种更有效的方式来编写以下内容,特别是因为过度使用了变量.如果有人能帮助我,我会非常感激.
<script type="text/javascript">
// calculate n!
Math.factorial = function(n)
{
if(typeof n == 'string') n = Number(n);
if(typeof n != 'number' || isNaN(n))
{
alert("Factorial requires a numeric argument.");
return null;
}
if (n < 2) return 1;
return (n * Math.factorial(n-1));
}
Math.divide = function(a,b)
{
return a/b;
}
</script>

我正在使用NGINX.可能是我的NGINX配置吗？

注意:我知道有类似的问题,但没有一个是完全相同的,答案是低于标准.
