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);

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();
我善意的回答是使用这个小小的JS: https://github.com/rhroyston/clock-js
clock.now --> 1462248501241
clock.time --> 11:08 PM
clock.weekday --> monday
clock.day --> 2
clock.month --> may
clock.year --> 2016
clock.since(1462245888784) --> 44 minutes
clock.until(1462255888784) --> 2 hours
clock.what.time(1462245888784) --> 10:24 PM
clock.what.weekday(1461968554458) --> friday
clock.what.day('14622458887 84') --> 2
clock.what.month(1461968554458) --> april
clock.what.year('1461968554458') --> 2016
clock.what.time() --> 11:11 PM
clock.what.weekday('14619685abcd') --> clock.js error : expected unix timestamp as argument
clock.unit.seconds --> 1000
clock.unit.minutes --> 60000
clock.unit.hours --> 3600000
clock.unit.days --> 86400000
clock.unit.weeks --> 604800000
clock.unit.months --> 2628002880
clock.unit.years --> 31536000000
<p id="DateTimeBox">点击按钮显示日期和时间 <按钮onclick = " ShowDate ();">显示日期</button> . < >脚本 函数ShowDate() { . getelementbyid(“DateTimeBox”)。innerHTML = Date(); ｝ > < /脚本
var currentdate = new Date();
var datetime = "Last Sync: " + currentdate.getDate() + "/"+(currentdate.getMonth()+1)
+ "/" + currentdate.getFullYear() + " @ "
+ currentdate.getHours() + ":"
+ currentdate.getMinutes() + ":" + currentdate.getSeconds();
将. getday()方法更改为. getdate()，并将1添加到month，因为它从0开始计算月份。
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
