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
获取当前日期和时间
var now = new Date();
var datetime = now.getFullYear()+'/'+(now.getMonth()+1)+'/'+now.getDate();
datetime += ' '+now.getHours()+':'+now.getMinutes()+':'+now.getSeconds();

它简单而精湛
$（document）.ready（function（） { var fpsOut = document.getElementById（'myTime'）; setInterval（function（） { var d = new Date（）; fpsOut.innerHTML = d; }, 1000); }); <script src=“https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js”></script> <div id=“myTime”></div>
请找到下面的提琴为例

这应该可以达到目的:
function dateToString(date) {
var month = date.getMonth() + 1;
var day = date.getDate();
var dateOfString = (("" + day).length < 2 ? "0" : "") + day + "/";
dateOfString += (("" + month).length < 2 ? "0" : "") + month + "/";
dateOfString += date.getFullYear();
return dateOfString;
}
var currentdate = new Date();
var datetime = "Last Sync: ";
datetime += dateToString(currentdate );
datetime += + currentdate.getHours() + ":"
+ currentdate.getMinutes() + ":"
+ currentdate.getSeconds();
这个问题很古老，答案也很古老。现在我们可以使用moment.js来获取当前日期，而不是那些怪异的函数，这实际上非常简单。所有要做的就是在我们的项目中包括moment.js，并获得一个格式良好的日期，例如，通过:
moment().format("dddd, MMMM Do YYYY, h:mm:ss a");
我认为这使得在javascript中处理日期更容易。
const date = new Date()
console.log(date.toLocaleTimeString("en-us", {timeStyle: "medium"})) // Only Time
console.log(date.toLocaleString()) // For both Date and Time
为文档
function UniqueDateTime(format='',language='en-US'){
//returns a meaningful unique number based on current time, and milliseconds, making it virtually unique
//e.g : 20170428-115833-547
//allows personal formatting like more usual :YYYYMMDDHHmmSS, or YYYYMMDD_HH:mm:SS
var dt = new Date();
var modele="YYYYMMDD-HHmmSS-mss";
if (format!==''){
modele=format;
}
modele=modele.replace("YYYY",dt.getFullYear());
modele=modele.replace("MM",(dt.getMonth()+1).toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false}));
modele=modele.replace("DD",dt.getDate().toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false}));
modele=modele.replace("HH",dt.getHours().toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false}));
modele=modele.replace("mm",dt.getMinutes().toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false}));
modele=modele.replace("SS",dt.getSeconds().toLocaleString(language, {minimumIntegerDigits: 2, useGrouping:false}));
modele=modele.replace("mss",dt.getMilliseconds().toLocaleString(language, {minimumIntegerDigits: 3, useGrouping:false}));
return modele;
}
