momentjs

问题 I have the util function that is parsing given date (i.e. '2019-01-28') in specific date format and then using momentJS retrieving beginning of that day and converting it to ISO date format: dates.js import moment from 'moment' export const getApiDateFormat = (date, dateFormat = getLocaleDateString()) => moment(date, dateFormat) .startOf('day') .toISOString() I would like to test this function using Jest and set the specific timezone for moment to use those tests independent of my location.

问题 I have the following string: "December 25, 2018 01:02:20" I intend this to be GMT/UTC Using moment.js, how do I convert this to local time and back to UTC? When I do: moment(myDateString).local() Then later to try to convert back: moment(myDateStrig).utc() They both yield different results. How do I make it so that I can convert the time I have from UTC to local, then back to UTC? Note: When I try the .utc() function on the string "December 25, 2018 01:02:20" I get a different time. When I do

问题 I've been trying to change the format of the dates that appear in the day column headers on the Fullcalendar week/timegrid view: I'm using V5 in conjuction with moment.js. Searching through the docs, I ended up here: https://fullcalendar.io/docs/v5/day-header-render-hooks This is the code I've tried when initialising the calendar: dayHeaderFormat: function(date){ return moment(date.weekday).format('ddd'); } This results in showing today (Thu) for every header, rather than the correct days. My

问题 I'm trying to change the first day of the work_week view with react big calendar but I didn't found a way to do it... I was able to change the first day of the week view but nothing helped with work week... any ideas? This is how I changed the first day of the week view: import "moment/locale/en-gb"; moment.locale("en-gb", { week: { dow: 0, }, }); const localizer = momentLocalizer(moment); 回答1: Unfortunately, the only way to do this is by defining a custom 'View', rather than using the 'work

问题 I want to create my own locale in moment.js, its parent should be the Arabic local but I want only to change to numeric format to display 0-9 , not the default display. As per documentation, I can start with that: moment.defineLocale('ar-sa-mine', { parentLocale: 'ar-sa', /* here I need to specify the numeric: change **this ٢٩ to 29** */ }); 回答1: If you look at locale/ar-sa.js code you will note that moment uses preparse and postformat to convert from numeric characters to arabic. You can

问题 I am looking for easy way to convert PHP date format (i.e. Y-m-d H:i:s) to javascript date format (respectively YYYY-mm-dd HH:mm:ss). I don't want to convert the date (there are already answers for this question), I am looking for tool/function to convert the format code (which I don't know yet, as it is defined by the user in application). User can define it in different ways defined by PHP date() i.e. 'Y/m/d H:i' or 'Y-d-m H-i' and I need to use the same format when displaying date in
