Javascript get date in format
提问by Samuel Meddows
I want to get today's date in the format of mm-dd-yyyy
我想以 mm-dd-yyyy 的格式获取今天的日期
I am using var currentDate = new Date();
document.write(currentDate);
我在用 var currentDate = new Date();
document.write(currentDate);
I can't figure out how to format it.
我不知道如何格式化它。
I saw the examples var currentTime = new Date(YY, mm, dd);and currentTime.format("mm/dd/YY");
我看到了例子var currentTime = new Date(YY, mm, dd);和currentTime.format("mm/dd/YY");
Both of which don't work
两者都不起作用
I finally got a properly formatted date using
我终于得到了一个格式正确的日期使用
var today = new Date();
var dd = today.getDate();
var mm = today.getMonth()+1;//January is 0!`
var yyyy = today.getFullYear();
if(dd<10){dd='0'+dd}
if(mm<10){mm='0'+mm}
var today = mm+'/'+dd+'/'+yyyy;
document.write(today);'`
This seems very complex for such a simple task.
对于这样一个简单的任务来说，这似乎非常复杂。
Is there a better way to get today's date in dd/mm/yyyy?
有没有更好的方法来获取今天的日期dd/mm/yyyy？

Unfortunately there is no better way, but instead of reinventing the wheel, you could use a library to deal with parsing and formatting dates: Datejs
不幸的是，没有更好的方法，但您可以使用库来处理解析和格式化日期，而不是重新发明轮子：Datejs

Or, if you find format specifiers ugly and hard to decipher, here's a concise formatting implementationthat allows you to use human-readable format specifiers (namely, the Date instance gettersthemselves):
或者，如果您发现格式说明符丑陋且难以破译，这里有一个简洁的格式实现，它允许您使用人类可读的格式说明符（即Date 实例 getter本身）：
date.format("{Month:2}-{Date:2}-{FullYear}"); // mm-dd-yyyy
</plug>

var today = new Date();
var strDate = 'Y-m-d'
.replace('Y', today.getFullYear())
.replace('m', today.getMonth()+1)
.replace('d', today.getDate());

Simple answer is no. Thats the only way to do it that I know of. You can probably wrap into a function that you can reuse many times.
简单的答案是否定的。这是我所知道的唯一方法。您可能可以包装成一个可以多次重用的函数。

function dateNow(splinter){
var set = new Date();
var getDate = set.getDate().toString();
if (getDate.length == 1){ //example if 1 change to 01
getDate = "0"+getDate;
}
var getMonth = (set.getMonth()+1).toString();
if (getMonth.length == 1){
getMonth = "0"+getMonth;
}
var getYear = set.getFullYear().toString();
var dateNow = getMonth +splinter+ getDate +splinter+ getYear; //today
return dateNow;
}
format this function is mm dd yyyy and the dividing you can choice and replace if you want... for example dateNow("/") you will get 12/12/2014
格式此函数为 mm dd yyyy 并且您可以根据需要选择和替换分割...例如 dateNow("/") 您将获得 12/12/2014

(new Date()).format("MM-dd-yyyy")
N.B. month is "MM" not "mm"
NB月份是“MM”而不是“mm”

There is nothing built in, but consider using this if you are already using jQuery (and if not, then you should consider that as well!)
没有内置任何东西，但是如果您已经在使用 jQuery，请考虑使用它（如果没有，那么您也应该考虑一下！）

function appendZeros(value,digits){
var c= 1;
initValue = value;
for(i=0;i<digits-1;i++){
c = c*10;
if( initValue < c ){
value = '0' + value;
}
}
return value;
}
