如何获得JavaScript的当前年份？

#1楼

这是获取日期的另一种方法

new Date().getDate()          // Get the day as a number (1-31)
new Date().getDay()           // Get the weekday as a number (0-6)
new Date().getFullYear()      // Get the four digit year (yyyy)
new Date().getHours()         // Get the hour (0-23)
new Date().getMilliseconds()  // Get the milliseconds (0-999)
new Date().getMinutes()       // Get the minutes (0-59)
new Date().getMonth()         // Get the month (0-11)
new Date().getSeconds()       // Get the seconds (0-59)
new Date().getTime()          // Get the time (milliseconds since January 1, 1970)

对于当前年份，我们可以使用Date类中的getFullYear（），但是根据需要可以使用许多功能，某些功能如下：

var now = new Date() console.log("Current Time is: " + now); // getFullYear function will give current year var currentYear = now.getFullYear() console.log("Current year is: " + currentYear); // getYear will give you the years after 1990 ie currentYear-1990 var year = now.getYear() console.log("Current year is: " + year); // getMonth gives the month value but months starts from 0 // add 1 to get actual month value var month = now.getMonth() + 1 console.log("Current month is: " + month); // getDate gives the date value var day = now.getDate() console.log("Today's day is: " + day);

这就是我将其嵌入并输出到HTML网页的方式：

<div class="container">
    <p class="text-center">Copyright &copy; 
        <script>
            var CurrentYear = new Date().getFullYear()
            document.write(CurrentYear)
        </script>
    </p>
</div>

输出到HTML页面如下：

您可以像这样简单地使用javascript。否则，您可以使用momentJs插件，该插件可在大型应用中提供帮助。

new Date().getDate()          // Get the day as a number (1-31)
new Date().getDay()           // Get the weekday as a number (0-6)
new Date().getFullYear()      // Get the four digit year (yyyy)
new Date().getHours()         // Get the hour (0-23)
new Date().getMilliseconds()  // Get the milliseconds (0-999)
new Date().getMinutes()       // Get the minutes (0-59)
new Date().getMonth()         // Get the month (0-11)
new Date().getSeconds()       // Get the seconds (0-59)
new Date().getTime()          // Get the time (milliseconds since January 1, 1970)

function generate(type,element) { var value = ""; var date = new Date(); switch (type) { case "Date": value = date.getDate(); // Get the day as a number (1-31) break; case "Day": value = date.getDay(); // Get the weekday as a number (0-6) break; case "FullYear": value = date.getFullYear(); // Get the four digit year (yyyy) break; case "Hours": value = date.getHours(); // Get the hour (0-23) break; case "Milliseconds": value = date.getMilliseconds(); // Get the milliseconds (0-999) break; case "Minutes": value = date.getMinutes(); // Get the minutes (0-59) break; case "Month": value = date.getMonth(); // Get the month (0-11) break; case "Seconds": value = date.getSeconds(); // Get the seconds (0-59) break; case "Time": value = date.getTime(); // Get the time (milliseconds since January 1, 1970) break; } $(element).siblings('span').text(value); }

li{ list-style-type: none; padding: 5px; } button{ width: 150px; } span{ margin-left: 100px; }

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <ul> <li> <button type="button" onclick="generate('Date',this)">Get Date</button> <span></span> </li> <li> <button type="button" onclick="generate('Day',this)">Get Day</button> <span></span> </li> <li> <button type="button" onclick="generate('FullYear',this)">Get Full Year</button> <span></span> </li> <li> <button type="button" onclick="generate('Hours',this)">Get Hours</button> <span></span> </li> <li> <button type="button" onclick="generate('Milliseconds',this)">Get Milliseconds</button> <span></span> </li> <li> <button type="button" onclick="generate('Minutes',this)">Get Minutes</button> <span></span> </li> <li> <button type="button" onclick="generate('Month',this)">Get Month</button> <span></span> </li> <li> <button type="button" onclick="generate('Seconds',this)">Get Seconds</button> <span></span> </li> <li> <button type="button" onclick="generate('Time',this)">Get Time</button> <span></span> </li> </ul>

以这个例子为例，您可以将其放置在任何想要显示的地方，而无需在页脚或其他答案中引用脚本

<script>new Date().getFullYear()>document.write(new Date().getFullYear());</script>

以页脚上的版权说明为例

Copyright 2010 - <script>new Date().getFullYear()>document.write(new Date().getFullYear());</script>
