//convert month to 2 digits<p>
var twoDigitMonth = ((fullDate.getMonth().length+1) === 1)? (fullDate.getMonth()+1) : '0' + (fullDate.getMonth()+1);

var currentDate =  fullDate.getFullYear()+ "/" + twoDigitMonth + "/" + fullDate.getDate();
console.log(currentDate);<br>
//2011/05/19

看到这个。 $.now()方法是表达式(new Date). gettime()返回的数字的简写。

这一行语句将给出YYYY-MM-DD:

new Date().toISOString().substr(0, 10)

'2022-06-09'

因为问题被标记为jQuery:

如果你也在使用jQuery UI，你可以使用$.datepicker.formatDate():

$.datepicker.formatDate('yy/mm/dd', new Date());

请看这个演示。

我只是想分享一个我用皮埃尔的想法做的时间戳原型。没有足够的点来评论:(

// US common date timestamp
Date.prototype.timestamp = function() {
  var yyyy = this.getFullYear().toString();
  var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based
  var dd  = this.getDate().toString();
  var h = this.getHours().toString();
  var m = this.getMinutes().toString();
  var s = this.getSeconds().toString();

  return (mm[1]?mm:"0"+mm[0]) + "/" + (dd[1]?dd:"0"+dd[0]) + "/" + yyyy + " - " + ((h > 12) ? h-12 : h) + ":" + m + ":" + s;
};

d = new Date();

var timestamp = d.timestamp();
// 10/12/2013 - 2:04:19

关闭jQuery插件页面。所以手动:

function strpad00(s)
{
    s = s + '';
    if (s.length === 1) s = '0'+s;
    return s;
}

var now = new Date();
var currentDate = now.getFullYear()+ "/" + strpad00(now.getMonth()+1) + "/" + strpad00(now.getDate());
console.log(currentDate );
