我有一个脚本,打印当前的日期和时间在JavaScript,但日期总是错误的。代码如下:

var currentdate = new Date();
var datetime = "Last Sync: " + currentdate.getDay() + "/" + currentdate.getMonth() 
+ "/" + currentdate.getFullYear() + " @ " 
+ currentdate.getHours() + ":" 
+ currentdate.getMinutes() + ":" + currentdate.getSeconds();

它应该打印18/04/2012 15:07:33和打印3/3/2012 15:07:33

我善意的回答是使用这个小小的JS: https://github.com/rhroyston/clock-js

clock.now   --> 1462248501241
clock.time  --> 11:08 PM
clock.weekday   --> monday
clock.day   --> 2
clock.month --> may
clock.year  --> 2016
clock.since(1462245888784)  --> 44 minutes
clock.until(1462255888784)  --> 2 hours
clock.what.time(1462245888784)  --> 10:24 PM
clock.what.weekday(1461968554458)   --> friday
clock.what.day('14622458887 84')    --> 2
clock.what.month(1461968554458) --> april
clock.what.year('1461968554458')    --> 2016
clock.what.time()   --> 11:11 PM
clock.what.weekday('14619685abcd')  -->     clock.js error : expected unix timestamp as argument
clock.unit.seconds  --> 1000
clock.unit.minutes  --> 60000
clock.unit.hours    --> 3600000
clock.unit.days --> 86400000
clock.unit.weeks    --> 604800000
clock.unit.months   --> 2628002880
clock.unit.years    --> 31536000000

简单地说:-

console.log(new Date().toLocaleString());

参考

来获得你应该使用的时间和日期

    new Date().toLocaleString();

>> "09/08/2014, 2:35:56 AM"

只得到你应该使用的日期

    new Date().toLocaleDateString();

>> "09/08/2014"

只得到你该用的时间

    new Date().toLocaleTimeString();

>> "2:35:56 AM"

或者如果你只是想要格式为hh:mm而不是AM/PM的美式英语时间

    new Date().toLocaleTimeString('en-US', { hour12: false, 
                                             hour: "numeric", 
                                             minute: "numeric"});
>> "02:35"

或英式英语

    new Date().toLocaleTimeString('en-GB', { hour: "numeric", 
                                             minute: "numeric"});

>> "02:35"

function getTimeStamp() {
       var now = new Date();
       return ((now.getMonth() + 1) + '/' + (now.getDate()) + '/' + now.getFullYear() + " " + now.getHours() + ':'
                     + ((now.getMinutes() < 10) ? ("0" + now.getMinutes()) : (now.getMinutes())) + ':' + ((now.getSeconds() < 10) ? ("0" + now
                     .getSeconds()) : (now.getSeconds())));
}

如果有人在寻找功能

console.log(formatAMPM());
function formatAMPM() {
  var date = new Date();
  var hours = date.getHours();
  var minutes = date.getMinutes();
  var seconds = date.getSeconds();
  var ampm = hours >= 12 ? 'PM' : 'AM';
  hours = hours % 12;
  hours = hours ? hours : 12; // the hour '0' should be '12'
  minutes = minutes < 10 ? '0'+minutes : minutes;
  return strTime = date.getMonth() + '/' + date.getDay()+'/'+date.getFullYear()+' '+ hours + ':' + minutes +':'+ seconds + " " +ampm;
}
var currentdate = new Date();

    var datetime = "Last Sync: " + currentdate.getDate() + "/"+(currentdate.getMonth()+1) 
    + "/" + currentdate.getFullYear() + " @ " 
    + currentdate.getHours() + ":" 
    + currentdate.getMinutes() + ":" + currentdate.getSeconds();

将. getday()方法更改为. getdate(),并将1添加到month,因为它从0开始计算月份。
