js根据年和月获取该月有几天:
/**
* 判断某年是否闰年
*/
export function isRuinian(year){
if(year/4 == 0 && year/100 != 0){
return 29;
} else if (year/400 == 0){
return 29;
} else{
return 28;
}
};
/**
* 根据年和月获取该月有几天
*/
export function getDayNumByYearMonth(year,month){
switch (month) {
case 1:
case 3:
case 5:
case 7:
case 8:
case 10:
case 12:
return 31;
break;
case 4:
case 6:
case 9:
case 11:
return 30;
break;
case 2:
return isRuinian(year);
}
};
先用export导出这个函数
然后在引用的页面用import导入这个函数:
import { getDayNumByYearMonth } from "../../assets/js/api/config";
