var dateObj = new Date();
var month = dateObj.getUTCMonth() + 1; //months from 1-12
var day = dateObj.getUTCDate();
var year = dateObj.getUTCFullYear();
newdate = year + "/" + month + "/" + day;
or you can set new date and give the above values
或者您可以设置新日期并提供上述值
回答by rahul
var dt = new Date();
dt.getFullYear() + "/" + (dt.getMonth() + 1) + "/" + dt.getDate();
Since month index are 0 based you have to increment it by 1.
由于月份索引是基于 0 的，因此您必须将其增加 1。

new Date().toISOString()
"2016-02-18T23:59:48.039Z"
new Date().toISOString().split('T')[0];
"2016-02-18"
new Date().toISOString().replace('-', '/').split('T')[0].replace('-', '/');
"2016/02/18"
new Date().toLocaleString().split(',')[0]
"2/18/2016"

I would suggest you to use Moment.js http://momentjs.com/
我建议你使用 Moment.js http://momentjs.com/
Then you can do:
然后你可以这样做：
moment(new Date()).format("YYYY/MM/DD");
Note: you don't actualy need to add new Date()if you want the current TimeDate, I only added it as a reference that you can pass a date object to it. for the current TimeDate this also works:
注意：new Date()如果您想要当前的 TimeDate，您实际上不需要添加，我只是将它添加为您可以将日期对象传递给它的参考。对于当前的 TimeDate 这也适用：
moment().format("YYYY/MM/DD");

EUROPE (ENGLISH/SPANISH) FORMAT
I you need to get the current day too, you can use this one.
欧洲（英语/西班牙语）格式
我也需要获取当前日期，您可以使用此格式。
function getFormattedDate(today)
{
var week = new Array('Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday');
var day = week[today.getDay()];
var dd = today.getDate();
var mm = today.getMonth()+1; //January is 0!
var yyyy = today.getFullYear();
var hour = today.getHours();
var minu = today.getMinutes();
if(dd<10) { dd='0'+dd }
if(mm<10) { mm='0'+mm }
if(minu<10){ minu='0'+minu }
return day+' - '+dd+'/'+mm+'/'+yyyy+' '+hour+':'+minu;
}
var date = new Date();
var text = getFormattedDate(date);
*For Spanish format, just translate the WEEK variable.
*对于西班牙语格式，只需翻译 WEEK 变量。
var week = new Array('Domingo', 'Lunes', 'Martes', 'Miércoles', 'Jueves', 'Viernes', 'Sábado');
Output: Monday - 16/11/2015 14:24
输出：星期一 - 16/11/2015 14:24

With the accepted answer, January 1st would be displayed like this: 2017/1/1.
随着接受的答案，1月1日将显示如下：2017/1/1。
If you prefer 2017/01/01, you can use:
如果您愿意2017/01/01，可以使用：
var dt = new Date();
var date = dt.getFullYear() + '/' + (((dt.getMonth() + 1) < 10) ? '0' : '') + (dt.getMonth() + 1) + '/' + ((dt.getDate() < 10) ? '0' : '') + dt.getDate();
