【Vue】实现出生日期计算年龄

    filters: {
        showAge(value) {
        // 指定日期
        let birthdays = new Date(value.replace(/-/g, "/"))
        // 当前系统日期
        let d = new Date();
        let age = d.getFullYear() - birthdays.getFullYear() -  (d.getMonth() < birthdays.getMonth() || (d.getMonth() == birthdays.getMonth() && d.getDate() < birthdays.getDate()) ? 1 : 0);
        return age
        }
    },
