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

. 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();
dt= new Date();
alert(dt.toISOString().substring(8,10) + "/" +
dt.toISOString().substring(5,7)+ "/" +
dt.toISOString().substring(0,4) + " " +
dt.toTimeString().substring(0,8))
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
简单地说:-
console.log(new Date().toLocaleString());
