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

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>

这是英国时区的例子。为特定时区设置偏移量。 例如:印度:+05:30，英国:+1
function realUKTime() {
// create Date object for current location
var d = new Date();
offset ='+1';
// convert to msec
// subtract local time zone offset
// get UTC time in msec
var utc = d.getTime() + (d.getTimezoneOffset() * 60000);
// create new Date object for different city
// using supplied offset
var nd = new Date(utc + (3600000*offset));
// return time as a string
var s = nd.getSeconds();
var i = nd.getMinutes();
var h = nd.getHours();
var cDate = nd.getDate();
var m = nd.getUTCMonth();
var y = nd.getFullYear();
var newUkTime = nd.toDateString() + " "+ (Number(h)-1)+":"+i+':'+s
$("#realTime").html(newUkTime);
}
setInterval(realUKTime(),1000);
输出::Mon 12月27日2021 12:6:3
您需要使用getDate()来获取日期部分。getDay()函数返回日期(Sunday = 0, Monday = 1…)，getMonth()返回一个基于0的索引，因此需要将其增加1。
var currentdate = new Date();
var datetime = "Last Sync: " + currentdate.getDate() + "/"+ (parseInt(currentdate.getMonth()) + 1)
+ "/" + currentdate.getFullYear() + " @ "
+ currentdate.getHours() + ":"
+ currentdate.getMinutes() + ":" + currentdate.getSeconds();
dt= new Date();
alert(dt.toISOString().substring(8,10) + "/" +
dt.toISOString().substring(5,7)+ "/" +
dt.toISOString().substring(0,4) + " " +
dt.toTimeString().substring(0,8))
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();
