这是我实现npm插件的方式

var monthNames = [
  "January", "February", "March",
  "April", "May", "June", "July",
  "August", "September", "October",
  "November", "December"
];

var Days = [
  "Sunday", "Monday", "Tuesday", "Wednesday",
  "Thursday", "Friday", "Saturday"
];

var formatDate = function(dt,format){
  format = format.replace('ss', pad(dt.getSeconds(),2));
  format = format.replace('s', dt.getSeconds());
  format = format.replace('dd', pad(dt.getDate(),2));
  format = format.replace('d', dt.getDate());
  format = format.replace('mm', pad(dt.getMinutes(),2));
  format = format.replace('m', dt.getMinutes());
  format = format.replace('MMMM', monthNames[dt.getMonth()]);
  format = format.replace('MMM', monthNames[dt.getMonth()].substring(0,3));
  format = format.replace('MM', pad(dt.getMonth()+1,2));
  format = format.replace(/M(?![ao])/, dt.getMonth()+1);
  format = format.replace('DD', Days[dt.getDay()]);
  format = format.replace(/D(?!e)/, Days[dt.getDay()].substring(0,3));
  format = format.replace('yyyy', dt.getFullYear());
  format = format.replace('YYYY', dt.getFullYear());
  format = format.replace('yy', (dt.getFullYear()+"").substring(2));
  format = format.replace('YY', (dt.getFullYear()+"").substring(2));
  format = format.replace('HH', pad(dt.getHours(),2));
  format = format.replace('H', dt.getHours());
  return format;
}

pad = function(n, width, z) {
  z = z || '0';
  n = n + '';
  return n.length >= width ? n : new Array(width - n.length + 1).join(z) + n;
}

这是一个完全符合您要求的脚本

https://github.com/UziTech/js-date-format

var d = new Date("2010-8-10");
document.write(d.format("DD-MMM-YYYY"));

只需执行以下操作：-

 let date = new Date().toLocaleDateString('en-us',{day: 'numeric'})
 let month = new Date().toLocaleDateString('en-us',{month: 'long'})
 let year = new Date().toLocaleDateString('en-us',{year: 'numeric'})
 const FormattedDate = `${date}-${month}-${year}`
 console.log(FormattedDate) // 26-March-2022

要获得“2010年8月10日”，请尝试：

var date = new Date('2010-08-10 00:00:00');
date = date.toLocaleDateString(undefined, {day:'2-digit'}) + '-' + date.toLocaleDateString(undefined, {month:'short'}) + '-' + date.toLocaleDateString(undefined, {year:'numeric'})

有关浏览器支持，请参阅toLocaleDateString。

new Date（）.toLocaleDateString（）// "3/21/2018"

截至2019年，您似乎可以使用LocaleDateString仅返回某些部分，然后您可以根据需要加入它们：

var date = new Date();

console.log(date.toLocaleDateString("en-US", { day: 'numeric' }) 
            + "-"+ date.toLocaleDateString("en-US", { month: 'short' })
            + "-" + date.toLocaleDateString("en-US", { year: 'numeric' }) );

console.log(date.toLocaleDateString("en-US", { month: 'long' }) 
            + " " + date.toLocaleDateString("en-US", { day: 'numeric' }) 
            + ", " + date.toLocaleDateString("en-US", { year: 'numeric' }) );
