你还可以: mydate.toLocaleDateString ();

你可以试试这个:

function formatDate(userDOB) { const dob = new Date(userDOB); const monthNames = [ 'January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December' ]; const day = dob.getDate(); const monthIndex = dob.getMonth(); const year = dob.getFullYear(); // return day + ' ' + monthNames[monthIndex] + ' ' + year; return `${day} ${monthNames[monthIndex]} ${year}`; } console.log(formatDate('1982-08-10'));

                //little bit of code for Converting dates 

                var dat1 = document.getElementById('inputDate').value;
                var date1 = new Date(dat1)//converts string to date object
                alert(date1);
                var dat2 = document.getElementById('inputFinishDate').value;
                var date2 = new Date(dat2)
                alert(date2);

这个答案是基于卡塞姆的答案，但它也适用于两位数的年份。我对卡塞姆的答案进行了编辑，但以防它没有被批准，我还将这个作为单独的答案提交。

function stringToDate(_date,_format,_delimiter) {
        var formatLowerCase=_format.toLowerCase();
        var formatItems=formatLowerCase.split(_delimiter);
        var dateItems=_date.split(_delimiter);
        var monthIndex=formatItems.indexOf("mm");
        var dayIndex=formatItems.indexOf("dd");
        var yearIndex=formatItems.indexOf("yyyy");
        var year = parseInt(dateItems[yearIndex]); 
        // adjust for 2 digit year
        if (year < 100) { year += 2000; }
        var month=parseInt(dateItems[monthIndex]);
        month-=1;
        var formatedDate = new Date(year,month,dateItems[dayIndex]);
        return formatedDate;
}

stringToDate("17/9/14","dd/MM/yyyy","/");
stringToDate("17/9/2014","dd/MM/yyyy","/");
stringToDate("9/17/2014","mm/dd/yyyy","/")
stringToDate("9-17-2014","mm-dd-yyyy","-")

如果你可以使用很棒的luxon库，你可以很容易地解析你的日期。

var luxonDate = DateTime.fromISO("2014-09-15T09:00:00");

和可以访问JS date对象通过

luxonDate().toJSDate();

旧的答案使用的是MomentJS

var momentDate = moment("2014-09-15 09:00:00");
momentDate ().toDate();

function stringToDate(_date,_format,_delimiter)
{
            var formatLowerCase=_format.toLowerCase();
            var formatItems=formatLowerCase.split(_delimiter);
            var dateItems=_date.split(_delimiter);
            var monthIndex=formatItems.indexOf("mm");
            var dayIndex=formatItems.indexOf("dd");
            var yearIndex=formatItems.indexOf("yyyy");
            var month=parseInt(dateItems[monthIndex]);
            month-=1;
            var formatedDate = new Date(dateItems[yearIndex],month,dateItems[dayIndex]);
            return formatedDate;
}

stringToDate("17/9/2014","dd/MM/yyyy","/");
stringToDate("9/17/2014","mm/dd/yyyy","/")
stringToDate("9-17-2014","mm-dd-yyyy","-")
