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

我发现了最简单的方法来获得当前的日期和时间在JavaScript从这里-如何获得当前的日期和时间使用JavaScript
var today = new Date();
var date = today.getFullYear()+'-'+(today.getMonth()+1)+'-'+today.getDate();
var time = today.getHours() + ":" + today.getMinutes() + ":" + today.getSeconds();
var CurrentDateTime = date+' '+time;
其他回答
只使用:
var d = new Date();
document.write(d.toLocaleString());
document.write("<br>");
我需要在后期特效里弄清楚这一点。以下是我从几个不同的来源获取元素后得出的结论——格式是MM/DD/YYYY HH:MM AM/PM
D = new Date(Date(00));
M = D.getMonth()+1;
H = D.getHours();
Mi = D.getMinutes();
N = "AM"
if (H >= 12)
N = "PM"
if (H > 12)
{
H = H-12
}
amtOfZeroes = 2;
isNeg = false;
if (M < 0)
{
M = Math.abs(M);
isNeg = true;
}
Mo = Math.round(M) + "";
while(Mo.length < amtOfZeroes)
{
Mo = "0" + Mo;
}
if (isNeg)
Mo = "-" + Mo;
if (H < 0)
{
H = Math.abs(H);
isNeg = true;
}
Ho = Math.round(H) + "";
while(Ho.length < amtOfZeroes)
{
Ho = "0" + Ho;
}
if (isNeg)
Ho = "-" + Ho;
if (Mi < 0)
{
Mi = Math.abs(Mi);
isNeg = true;
}
Min = Math.round(Mi) + "";
while(Min.length < amtOfZeroes)
{
Min = "0" + Min;
}
if (isNeg)
Min = "-" + Min;
T = Ho + ":" + (Min)
Mo + "/" + D.getDate() + "/" + D.getFullYear() + " " + T + " " + N
const date = new Date()
console.log(date.toLocaleTimeString("en-us", {timeStyle: "medium"})) // Only Time
console.log(date.toLocaleString()) // For both Date and Time
为文档
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 UniqueDateTime(format='',language='en-US'){
