I am getting an "Invalid date" error when I translate my dates from Spanish to English with moment.js (with locales). The weird thing here, is that only fails with some dates.
I have a list of dates, apparently of the same format (they were parsed before using the same library). Then when I parsed it again after change the moment.js locale (To translate my dates to the desired language) I get this:
Enero 13º 2017, 6:00:02 Am --> Invalid date
Abril 17º 2017, 7:36:03 Pm --> Invalid date
Abril 17º 2017, 6:00:01 Am --> Invalid date
Mayo 12º 2017, 2:04:19 Pm --> May 12th 2017, 2:04:19 Pm
Abril 17º 2017, 11:47:17 Pm --> Invalid date
Parse Method (format is initialized here because in other moments it can get other values):
format = 'MMMM Do YYYY, h:mm:ss a';
$(".videoDate").each(function(){
var _text = $(this).text();//Extract initial date
var _date = moment(_text, format).format('MMMM Do YYYY, h:mm:ss a');//format
$(this).text(_date);//new date setting
});
Maybe I am missing something but I don't find the reason yet. Can any help me with this problem?
You can specify locale when parsing non-english input. You can use moment(String, String, String)
:
As of version 2.0.0 , a locale key can be passed as the third parameter to
moment()
andmoment.utc()
.
You can use locale()
function to change locale of a given moment object (while moment.locale()
changes locale globally).
Here a working sample:
var format = 'MMMM Do YYYY, h:mm:ss a'; $(".videoDate").each(function(){ var _text = $(this).text();//Extract initial date //Parse in spanish and convert it in english var _date = moment(_text, format, 'es') .locale('en') .format('MMMM Do YYYY, h:mm:ss a');//format $(this).text(_date);//new date setting });

Mayo 12º 2017, 2:04:19 Pm
is recognized beacuse by default moment parses strings using english locale and Moment's parser is very forgiving . Mayo
contains May
so it is considered a valid month name (using forgiving mode ).
