关于日期:使用JavaScript获取当前年份

Get the current year in JavaScript

如何在JavaScript中获取当前年份?


创建new Date()对象并调用getFullYear()

1
2
new Date().getFullYear()
// returns the current year

劫持已接受的答案,提供一些基本的示例上下文,如页脚始终显示当前年份:

1
2
3
<footer>
    &copy; <span id="year">2018</span>
</footer>

在上面的HTML加载后执行的其他地方:

1
    document.getElementById("year").innerHTML = new Date().getFullYear();

1
document.getElementById("year").innerHTML = new Date().getFullYear();
1
2
3
4
footer {
  text-align: center;
  font-family: sans-serif;
}

3
<footer>
    &copy; <span id="year">2018</span> by FooBar
</footer>

// 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)


这是另一种获取日期的方法

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)

对于今年我们可以使用Date类的getFullYear()但是有很多功能你可以按照要求使用,有些功能是,

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);


你可以简单地使用这样的javascript。 否则你可以使用momentJs插件,这有助于大型应用程序。

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)

这就是我将它嵌入并输出到我的HTML网页的方式:

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

输出到HTML页面如下:
