ISO 8601式的数据字符串，尽管标准很优秀，但仍然没有得到广泛的支持。

这是一个很好的资源来找出你应该使用哪种datestring格式:

http://dygraphs.com/date-formats.html

是的，这意味着你的datestring可以简单的反对

“2014/10/13 23:57:52” 而不是 “2014-10-13 23:57:52”

时间戳应该转换为一个数字

var ts = '1471793029764';
ts = Number(ts); // cast it to a Number
var date = new Date(ts); // works

var invalidDate = new Date('1471793029764'); // does not work. Invalid Date

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();

我已经创建了parseDateTime函数将字符串转换为日期对象，它在所有浏览器(包括IE浏览器)中工作，检查是否有人需要，引用 https://github.com/Umesh-Markande/Parse-String-to-Date-in-all-browser

    function parseDateTime(datetime) {
            var monthNames = [
                "January", "February", "March",
                "April", "May", "June", "July",
                "August", "September", "October",
                "November", "December"
              ];
            if(datetime.split(' ').length == 3){
                var date = datetime.split(' ')[0];
                var time = datetime.split(' ')[1].replace('.00','');
                var timearray = time.split(':');
                var hours = parseInt(time.split(':')[0]);
                var format = datetime.split(' ')[2];
                var bits = date.split(/\D/);
                date = new Date(bits[0], --bits[1], bits[2]); /* if you change format of datetime which is passed to this function, you need to change bits e.x ( bits[0], bits[1], bits[2 ]) position as per date, months and year it represent bits array.*/
                var day = date.getDate();
                var monthIndex = date.getMonth();
                var year = date.getFullYear();
                if ((format === 'PM' || format === 'pm') && hours !== 12) {
                    hours += 12;
                    try{  time = hours+':'+timearray[1]+':'+timearray[2] }catch(e){ time = hours+':'+timearray[1] }
                } 
                var formateddatetime = new Date(monthNames[monthIndex] + ' ' + day + '  ' + year + ' ' + time);
                return formateddatetime;
            }else if(datetime.split(' ').length == 2){
                var date = datetime.split(' ')[0];
                var time = datetime.split(' ')[1];
                var bits = date.split(/\D/);
                var datetimevalue = new Date(bits[0], --bits[1], bits[2]); /* if you change format of datetime which is passed to this function, you need to change bits e.x ( bits[0], bits[1], bits[2 ]) position as per date, months and year it represent bits array.*/
                var day = datetimevalue.getDate();
                var monthIndex = datetimevalue.getMonth();
                var year = datetimevalue.getFullYear();
                var formateddatetime = new Date(monthNames[monthIndex] + ' ' + day + '  ' + year + ' ' + time);
                return formateddatetime;
            }else if(datetime != ''){
                var bits = datetime.split(/\D/);
                var date = new Date(bits[0], --bits[1], bits[2]); /* if you change format of datetime which is passed to this function, you need to change bits e.x ( bits[0], bits[1], bits[2 ]) position as per date, months and year it represent bits array.*/
                return date;
            }
            return datetime;
        }

    var date1 = '2018-05-14 05:04:22 AM';   // yyyy-mm-dd hh:mm:ss A
    var date2 = '2018/05/14 05:04:22 AM';   // yyyy/mm/dd hh:mm:ss A
    var date3 = '2018/05/04';   // yyyy/mm/dd
    var date4 = '2018-05-04';   // yyyy-mm-dd
    var date5 = '2018-05-14 15:04:22';   // yyyy-mm-dd HH:mm:ss
    var date6 = '2018/05/14 14:04:22';   // yyyy/mm/dd HH:mm:ss

    console.log(parseDateTime(date1))
    console.log(parseDateTime(date2))
    console.log(parseDateTime(date3))
    console.log(parseDateTime(date4))
    console.log(parseDateTime(date5))
    console.log(parseDateTime(date6))

不幸的是，我发现了

var mydate =新日期(2014-04-03); 游戏机。log (mydate toDateString ());

返回“2014年4月2日星期三”。我知道这听起来很疯狂，但这确实发生在一些用户身上。

防弹方案如下:

Var parts ='2014-04-03'.split('-'); //请关注月份(零件[1]);JavaScript从0开始计算月份: // 1月- 0日，2月- 1日，等等。 var mydate =新的日期(部分[0]，部分[1]- 1，部分[2]); console.log (mydate.toDateString ());
