                }
                if(Year(year)&&month>2){
                    days++;
                }
                return days;
            }
            function Year(year){
                return year%4==0&&year%100!=0||year%400==0;
            }
            console.log(time (2013,2,1))
            // console.log(time ('2013,2,1)')改成这个
        </script>
    </body>
</html>

参数改成字符串？可以在函数内split下就行，代码如下



        function time(s) {
            var arr = s.split(',').map(i => parseInt(i));
            var year = arr[0], month = arr[1], day = arr[2]
            var days = day;
            if (month == 1) {
                return days;
            }
            var months = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]
            for (var i = 0; i < month - 1; i++) {
                days += months[i]
            }
            if (Year(year) && month > 2) {
                days++;
            }
            return days;
        }
        function Year(year) {
            return year % 4 == 0 && year % 100 != 0 || year % 400 == 0;
        }
       // console.log(time(2013, 2, 1))
        console.log(time('2013,2,1)'))
