使用 JavaScript 获取当前年份

如何获得 JavaScript 的当前年份?

答案

new Date().getFullYear()
// returns the current year
<footer>
    &copy; <span id="year"></span>
</footer>
<script>
    document.getElementById("year").innerHTML = new Date().getFullYear();
</script>
// Return today's date and time
var currentTime = new Date()

// returns the month (from 0 to 11)
var month = currentTime.getMonth() + 1

// returns the day of the month (from 1 to 31)
var day = currentTime.getDate()

// returns the year (four digits)
var year = currentTime.getFullYear()

// write output MM/dd/yyyy
document.write(month + "/" + day + "/" + year)
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)
<div class="container">
    <p class="text-center">Copyright &copy; 
        <script>
            var CurrentYear = new Date().getFullYear()
            document.write(CurrentYear)
        </script>
    </p>
</div>

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 i.e 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);

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