DateConv is a javascript class which converts Date objects into String objects, or the other way around.
I decided to wrote this simple tool because I found there are no similar tools available. All I need is a simple converter that supports simple formats, and this is what DateConv turned out to be.
You can copy / modify the code at your will.
To use DateConv, add this to your code:
<script type="text/javascript" src="dateconv-min.js"></script>
DateConv uses a pattern format similar to Java's SimpleDateFormat class, but doesn't exactly follow SDF's rules. DateConv's patterns are much simpler.
| Format | Stands For | Remarks |
|---|---|---|
| yyyy | 4 digits year | |
| yy | 2 digits year | toDate() doesn't support this format |
| MM | Month in year with zero padding, 01 - 12 | |
| M | Month in year, 1 - 12 | toDate() doesn't support this format |
| dd | Day in month with zero padding, 01 - 31 | |
| d | Day in month, 1 - 31 | toDate() doesn't support this format |
| HH | Hour in day with zero padding, 00 - 23 | |
| H | Hour in day, 0 - 23 | toDate() doesn't support this format |
| mm | Minute in hour with zero padding, 00 - 59 | |
| m | Minute in hour, 0 - 59 | toDate() doesn't support this format |
| ss | Second in minute with zero padding, 00 - 59 | |
| s | Second in minute, 0 - 59 | toDate() doesn't support this format |
| SSS | Millisecond in second with zero padding, 000 - 999 | |
| S | Millisecond in second, 0 - 999 | toDate() doesn't support this format |
DateConv.toString(date, format)Usage
var str = DateConv.toString(new Date(), 'd/M/yyyy HH:mm:ss.S');
DateConv.toDate(str, format)Usage
var date = DateConv.toDate('09/11, 2001, 08:46:00', 'MM/dd, yyyy, HH:mm:ss');
Notes
DateConv.toDate() returns null when:
DateConv.toDate('33/01/1981', 'dd/MM/yyyy'), where the day of month is obviously invalidnew Date(year, month, day, hour, minute, second, millisecond) to construct Date objects, any date parts that are not specified in the date string, will be replaced by 0 (except the day of month, which will be replaced by 1).DateConv.toDate() only checks if it's in the 1 - 31 range. Thus 2008/02/31 will actually be translated as 2008/03/02, so be careful.DateConv.toString() will return invalid year in this case.
