如何将字符串转换为JavaScript日期对象?
var st = "date in some format"
var dt = new Date();
var dt_st = // st in Date format, same as dt.

对于在js中转换字符串到日期，我使用http://momentjs.com/
moment().format('MMMM Do YYYY, h:mm:ss a'); // August 16th 2015, 4:17:24 pm
moment().format('dddd'); // Sunday
moment().format("MMM Do YY"); // Aug 16th 15
moment().format('YYYY [escaped] YYYY'); // 2015 escaped 2015
moment("20111031", "YYYYMMDD").fromNow(); // 4 years ago
moment("20120620", "YYYYMMDD").fromNow(); // 3 years ago
moment().startOf('day').fromNow(); // 16 hours ago
moment().endOf('day').fromNow(); // in 8 hours

使用此格式....
//get current date in javascript
var currentDate = new Date();
// for getting a date from a textbox as string format
var newDate=document.getElementById("<%=textBox1.ClientID%>").value;
// convert this date to date time
var MyDate = new Date(newDate);
对于那些正在寻找小巧而智能的解决方案的人:
String.prototype.toDate = function(format)
{
var normalized = this.replace(/[^a-zA-Z0-9]/g, '-');
var normalizedFormat= format.toLowerCase().replace(/[^a-zA-Z0-9]/g, '-');
var formatItems = normalizedFormat.split('-');
var dateItems = normalized.split('-');
var monthIndex = formatItems.indexOf("mm");
var dayIndex = formatItems.indexOf("dd");
var yearIndex = formatItems.indexOf("yyyy");
var hourIndex = formatItems.indexOf("hh");
var minutesIndex = formatItems.indexOf("ii");
var secondsIndex = formatItems.indexOf("ss");
var today = new Date();
var year = yearIndex>-1 ? dateItems[yearIndex] : today.getFullYear();
var month = monthIndex>-1 ? dateItems[monthIndex]-1 : today.getMonth()-1;
var day = dayIndex>-1 ? dateItems[dayIndex] : today.getDate();
var hour = hourIndex>-1 ? dateItems[hourIndex] : today.getHours();
var minute = minutesIndex>-1 ? dateItems[minutesIndex] : today.getMinutes();
var second = secondsIndex>-1 ? dateItems[secondsIndex] : today.getSeconds();
return new Date(year,month,day,hour,minute,second);
};
例子:
"22/03/2016 14:03:01".toDate("dd/mm/yyyy hh:ii:ss");
"2016-03-29 18:30:00".toDate("yyyy-mm-dd hh:ii:ss");
只是新日期(st);
假设这是正确的格式。
新的日期(2000,10,1)将给你“星期三11月1日2000 00:00:00 GMT+0100 (CET)”
0表示month，表示1月
你还可以: mydate.toLocaleDateString ();
