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
当前回答
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。

我开发史蒂夫的答案，以确切地了解OP需要什么
new Date().toLocaleString().replace(',','')
.toLocaleString console.log(新日期()().replace (',',''));
. 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。
const date = new Date()
console.log(date.toLocaleTimeString("en-us", {timeStyle: "medium"})) // Only Time
console.log(date.toLocaleString()) // For both Date and Time

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();
