There is no native format in javascript for DD-Mon-YYYY.
javascript 中没有用于DD-Mon-YYYY.
You will have to put it all together manually.
您必须手动将它们放在一起。
The answer is inspired from : How to format a JavaScript date
答案灵感来自： How to format a JavaScript date
// Attaching a new function toShortFormat() to any instance of Date() class
Date.prototype.toShortFormat = function() {
let monthNames =["Jan","Feb","Mar","Apr",
"May","Jun","Jul","Aug",
"Sep", "Oct","Nov","Dec"];
let day = this.getDate();
let monthIndex = this.getMonth();
let monthName = monthNames[monthIndex];
let year = this.getFullYear();
return `${day}-${monthName}-${year}`;
}
// Now any Date object can be declared
let anyDate = new Date(1528578000000);
// and it can represent itself in the custom format defined above.
console.log(anyDate.toShortFormat()); // 10-Jun-2018
let today = new Date();
console.log(today.toShortFormat()); // today's date回答by Klemen Tu?ar
Use the Moment.js library http://momentjs.com/It will save you a LOT of trouble.
使用 Moment.js 库http://momentjs.com/它会为你省去很多麻烦。

You can use toLocaleDateStringand hunt for a format that's close to DD-mmm-YYYY (hint: 'en-GB'; you just need to replace the spaces with '-').
您可以使用toLocaleDateString并寻找接近 DD-mmm-YYYY 的格式（提示：'en-GB'；您只需要将空格替换为 '-'）。
const date = new Date();
const formattedDate = date.toLocaleDateString('en-GB', {
day: 'numeric', month: 'short', year: 'numeric'
}).replace(/ /g, '-');
console.log(formattedDate);回答by Yanga
Can be done with toLocaleDateString
可以用 toLocaleDateString
<script>
const date = new Date();
const formattedDate = date.toLocaleDateString('en-GB', {
day: '2-digit', month: 'short', year: 'numeric'
}).replace(/ /g, '-');
document.write(formattedDate);
</script>回答by Indranil Mondal
I've made a custom date string format function, you can use that.
我已经制作了一个自定义日期字符串格式函数，您可以使用它。
var getDateString = function(date, format) {
var months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
getPaddedComp = function(comp) {
return ((parseInt(comp) < 10) ? ('0' + comp) : comp)
},
formattedDate = format,
o = {
"y+": date.getFullYear(), // year
"M+": months[date.getMonth()], //month
"d+": getPaddedComp(date.getDate()), //day
"h+": getPaddedComp((date.getHours() > 12) ? date.getHours() % 12 : date.getHours()), //hour
"H+": getPaddedComp(date.getHours()), //hour
"m+": getPaddedComp(date.getMinutes()), //minute
"s+": getPaddedComp(date.getSeconds()), //second
"S+": getPaddedComp(date.getMilliseconds()), //millisecond,
"b+": (date.getHours() >= 12) ? 'PM' : 'AM'
};
for (var k in o) {
if (new RegExp("(" + k + ")").test(format)) {
formattedDate = formattedDate.replace(RegExp., o[k]);
}
}
return formattedDate;
};
And now suppose you've :-
现在假设你已经：-
var date = "2014-07-12 10:54:11";
So to format this date you write:-
所以要格式化这个日期，你写：-
var formattedDate = getDateString(new Date(date), "d-M-y")

Using the Intl object (or via toLocaleString) is somewhat problematic, but it can be made precise using the formatToPartsmethodand manually putting the parts in order, e.g.
使用 Intl 对象（或通过toLocaleString）有些问题，但可以使用formatToParts方法并手动将部件按顺序排列，例如
function formatDate(date = new Date()) {
let {day, month, year} = new Intl.DateTimeFormat('en', {
day:'2-digit',
month: 'short',
year: 'numeric'
}).formatToParts(date).reduce((acc, part) => {
if (part.type != 'literal') {
acc[part.type] = part.value;
}
return acc;
}, Object.create(null));
return `${day}-${month}-${year}`;
}
console.log(formatDate());Using reduceon the array returned by formatToPartstrims out the literals and creates an object with named properties that is then assigned to variables and finally formatted.
在formatToParts返回的数组上使用reduce会修剪掉文字并创建一个具有命名属性的对象，然后将其分配给变量并最终格式化。
This function doesn't always work nicely for languages other than English though as the short month name may have punctuation.
此功能并不总是适用于英语以外的语言，尽管短月份名称可能有标点符号。

the DD-MM-YYYY is just one of the formats. The format of the jquery plugin, is based on this list: http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html
DD-MM-YYYY 只是其中一种格式。jquery 插件的格式基于此列表：http: //docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html
Tested following code in chrome console:
