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

基本JS(很好学习):我们使用Date()函数，并做所有我们需要显示日期和日期在我们的自定义格式。
var myDate = new Date(); let daysList = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday']; let monthsList = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Aug', 'Oct', 'Nov', 'Dec']; let date = myDate.getDate(); let month = monthsList[myDate.getMonth()]; let year = myDate.getFullYear(); let day = daysList[myDate.getDay()]; let today = `${date} ${month} ${year}, ${day}`; let amOrPm; let twelveHours = function (){ if(myDate.getHours() > 12) { amOrPm = 'PM'; let twentyFourHourTime = myDate.getHours(); let conversion = twentyFourHourTime - 12; return `${conversion}` }else { amOrPm = 'AM'; return `${myDate.getHours()}`} }; let hours = twelveHours(); let minutes = myDate.getMinutes(); let currentTime = `${hours}:${minutes} ${amOrPm}`; console.log(today + ' ' + currentTime);
Node JS(快速简单):使用(npm安装日期和时间)安装npm页面，然后运行以下命令。
let nodeDate = require('date-and-time');
let now = nodeDate.format(new Date(), 'DD-MMMM-YYYY, hh:mm:ss a');
console.log(now);

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>
只使用:
var d = new Date();
document.write(d.toLocaleString());
document.write("<br>");
试试这个:
var today = new Date();
var date = today.getFullYear()+'-'+(today.getMonth()+1)+'-'+today.getDate();
var time = today.getHours() + ":" + today.getMinutes() + ":" + today.getSeconds();
var dateTime = date+' '+time;
输出:
2022-3-3 15:52:45
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
. getday返回星期几。你需要用. getdate代替。 . getmonth返回0到11的值。您需要在结果中添加1以获得“人类”月份数。
