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

其他回答

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"

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
