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

这个小代码很简单，在任何地方都可以工作。
<p id="dnt"></p>
<script>
document.getElementById("dnt").innerHTML = Date();
</script>
这里有设计的空间

我们可以用: new Date().toLocaleDateString()获取当前日期和 new Date().toLocaleTimeString()获取当前时间
Ex:
const date = new Date().toLocaleDateString();
const time = new Date().toLocaleTimeString();
对于真正的mysql样式输出使用下面的函数:2019/02/28 15:33:12
如果你点击下面的“运行代码片段”按钮 它将向您展示一个简单的实时数字时钟示例 演示程序将出现在代码片段的下面。
function getDateTime() { var now = new Date(); var year = now.getFullYear(); var month = now.getMonth()+1; var day = now.getDate(); var hour = now.getHours(); var minute = now.getMinutes(); var second = now.getSeconds(); if(month.toString().length == 1) { month = '0'+month; } if(day.toString().length == 1) { day = '0'+day; } if(hour.toString().length == 1) { hour = '0'+hour; } if(minute.toString().length == 1) { minute = '0'+minute; } if(second.toString().length == 1) { second = '0'+second; } var dateTime = year+'/'+month+'/'+day+' '+hour+':'+minute+':'+second; return dateTime; } // example usage: realtime clock setInterval(function(){ currentTime = getDateTime(); document.getElementById("digital-clock").innerHTML = currentTime; }, 1000); <div id="digital-clock"></div>
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"

Here is my work around clock full format with day, date, year and time and make Sure the date of your PC is set to the right date and if you are using PHP make sure in php.ini date.timezone= xx where xx your current timezone function startTime() { var today=new Date(); // 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 var suffixes = ['','st','nd','rd','th','th','th','th','th','th','th','th','th','th','th','th','th','th','th','th','th','st','nd','rd','th','th','th','th','th','th','th','st','nd','rd']; var weekday = new Array(7); weekday[0] = "Sunday"; weekday[1] = "Monday"; weekday[2] = "Tuesday"; weekday[3] = "Wednesday"; weekday[4] = "Thursday"; weekday[5] = "Friday"; weekday[6] = "Saturday"; var month = new Array(12); month[0] = "January"; month[1] = "February"; month[2] = "March"; month[3] = "April"; month[4] = "May"; month[5] = "June"; month[6] = "July"; month[7] = "August"; month[8] = "September"; month[9] = "October"; month[10] = "November"; month[11] = "December"; document.getElementById('txt').innerHTML=(weekday[today.getDay()] + ',' + " " + today.getDate()+'<sup>'+suffixes[today.getDate()]+'</sup>' + ' of' + " " + month[today.getMonth()] + " " + today.getFullYear() + ' Time Now ' + today.toLocaleTimeString()); t=setTimeout(function(){startTime()},500); } <style> sup { vertical-align: super; font-size: smaller; } </style> <html> <body onload="startTime()"> <div id="txt"></div> </body> </html>
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
