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
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。
. getmonth()返回一个从零开始的数字，所以为了得到正确的月份，你需要加1，所以在五月调用. getmonth()将返回4而不是5。
因此，在代码中，我们可以使用currentdate.getMonth()+1来输出正确的值。此外:
.getDate()返回月份的日期<-这是你想要的 .getDay()是Date对象的一个单独方法，它将返回一个整数，表示一周中的当前日期(0-6)0 ==星期日等
所以你的代码应该是这样的:
var currentdate = new Date();
var datetime = "Last Sync: " + currentdate.getDate() + "/"
+ (currentdate.getMonth()+1) + "/"
+ currentdate.getFullYear() + " @ "
+ currentdate.getHours() + ":"
+ currentdate.getMinutes() + ":"
+ currentdate.getSeconds();
JavaScript Date实例继承自Date.prototype。您可以修改构造函数的原型对象，以影响JavaScript Date实例继承的属性和方法
您可以使用Date原型对象创建一个新方法，该方法将返回今天的日期和时间。这些新方法或属性将由Date对象的所有实例继承，因此在需要重用此功能时特别有用。
// For todays date;
Date.prototype.today = function () {
return ((this.getDate() < 10)?"0":"") + this.getDate() +"/"+(((this.getMonth()+1) < 10)?"0":"") + (this.getMonth()+1) +"/"+ this.getFullYear();
}
// For the time now
Date.prototype.timeNow = function () {
return ((this.getHours() < 10)?"0":"") + this.getHours() +":"+ ((this.getMinutes() < 10)?"0":"") + this.getMinutes() +":"+ ((this.getSeconds() < 10)?"0":"") + this.getSeconds();
}
然后，您可以通过执行以下操作简单地检索日期和时间:
var newDate = new Date();
var datetime = "LastSync: " + newDate.today() + " @ " + newDate.timeNow();
或者将该方法调用为内联，这样它就是-
var datetime = "LastSync: " + new Date().today() + " @ " + new Date().timeNow();
getDay()获取星期几。3号是星期三。你需要getDate()，它会返回18。
同样，getMonth()从0开始，你需要加1来得到4(四月)。
演示:http://jsfiddle.net/4zVxp/
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();
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();
function getTimeStamp() {
var now = new Date();
return ((now.getMonth() + 1) + '/' + (now.getDate()) + '/' + now.getFullYear() + " " + now.getHours() + ':'
+ ((now.getMinutes() < 10) ? ("0" + now.getMinutes()) : (now.getMinutes())) + ':' + ((now.getSeconds() < 10) ? ("0" + now
.getSeconds()) : (now.getSeconds())));
}

这里有设计的空间
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。
只使用:
var d = new Date();
document.write(d.toLocaleString());
document.write("<br>");
来获得你应该使用的时间和日期
new Date().toLocaleString();
>> "09/08/2014, 2:35:56 AM"
只得到你应该使用的日期
new Date().toLocaleDateString();
>> "09/08/2014"
只得到你该用的时间
new Date().toLocaleTimeString();
>> "2:35:56 AM"
或者如果你只是想要格式为hh:mm而不是AM/PM的美式英语时间
new Date().toLocaleTimeString('en-US', { hour12: false,
hour: "numeric",
minute: "numeric"});
>> "02:35"
或英式英语
new Date().toLocaleTimeString('en-GB', { hour: "numeric",
minute: "numeric"});
>> "02:35"

我需要在后期特效里弄清楚这一点。以下是我从几个不同的来源获取元素后得出的结论——格式是MM/DD/YYYY HH:MM AM/PM
D = new Date(Date(00));
M = D.getMonth()+1;
H = D.getHours();
Mi = D.getMinutes();
N = "AM"
if (H >= 12)
N = "PM"
if (H > 12)
{
H = H-12
}
amtOfZeroes = 2;
isNeg = false;
if (M < 0)
{
M = Math.abs(M);
isNeg = true;
}
Mo = Math.round(M) + "";
while(Mo.length < amtOfZeroes)
{
Mo = "0" + Mo;
}
if (isNeg)
Mo = "-" + Mo;
if (H < 0)
{
H = Math.abs(H);
isNeg = true;
}
Ho = Math.round(H) + "";
while(Ho.length < amtOfZeroes)
{
Ho = "0" + Ho;
}
if (isNeg)
Ho = "-" + Ho;
if (Mi < 0)
{
Mi = Math.abs(Mi);
isNeg = true;
}
Min = Math.round(Mi) + "";
while(Min.length < amtOfZeroes)
{
Min = "0" + Min;
}
if (isNeg)
Min = "-" + Min;
T = Ho + ":" + (Min)
Mo + "/" + D.getDate() + "/" + D.getFullYear() + " " + T + " " + N

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);

var ampm = hours >= 12 ? 'PM' : 'AM';
hours = hours % 12;
hours = hours ? hours : 12; // the hour '0' should be '12'

// convert to msec
// subtract local time zone offset
// get UTC time in msec

// create new Date object for different city
// using supplied offset
