我正在寻找一个 JavaScript 或 PHP 脚本，它允许我根据某人的出生日期以mm/dd/yyyy格式计算某人的年龄。我发现这个非常有用的链接“ Calculate age in JavaScript ”，但它似乎是为处理用户输入而设计的。但是，我正在创建一个页面，将 DOB 作为简单文本直接放入 HTML 中。那么还可以计算年龄吗？基本上，我希望这行文本成为最终结果：

29 (10/17/1983)

29自动计算并显示为年龄的值。

如果这样的事情是可能的，我将非常感谢您的帮助。我对 PHP 和/或 jQuery 相当熟悉，但我当然不是高级专业人士。

PHP：

$today = new DateTime();
$birthdate = new DateTime("1973-04-18 09:48:00");
$interval = $today->diff($birthdate);
echo $interval->format('%y years');

看到它在行动。您显然可以格式化输出以满足您的需求。

Javascript：

这可能比您要求的更多，但会给您以年、月和日为单位的年龄。

像这样： 8 years, 7 months, 21 days old

如果您有一个只有几天大的新生儿的网站，这很有效。

这是我大约 9 年前在我女儿的网站上使用的东西

    function GetMyAge()
{
<!--

todaysYear = todaysTime.getFullYear()

todaysDate = todaysTime.getDate()
todaysHour = todaysTime.getHours()

birthYear = birthTime.getFullYear()
birthMonth = birthTime.getMonth()
birthDate = birthTime.getDate()
birthHour = birthTime.getHours()
birthMinute = birthTime.getMinutes()
birthSecond = birthTime.getSeconds()

<!-- Adjusts for Leap Year Info
if ((todaysYear / 4) == (Math.round(todaysYear / 4))) {
   countLeap = 29}

     countLeap = 28}

<!-- Calculate the days in the month
if (todaysMonth == 2) {
   countMonth = countLeap}

在javascript中你可以计算它：

function getAge(dateString) {
    var today = new Date();
    var birthDate = new Date(dateString);
    var age = today.getFullYear() - birthDate.getFullYear();
    var m = today.getMonth() - birthDate.getMonth();
    if (m < 0 || (m === 0 && today.getDate() < birthDate.getDate())) {
        age--;
    }
    return age;
}

计算年龄的最简单方法是：

CURRENT YEAR - BIRTH YEAR = AGE  
IF(CURRENT MONTH DAY < BIRTH MONTH DAY) AGE--;

IE 还活着但 -1 如果你还没有过生日

MONTH DAY 是 3 月 1 日的 0301
