Converting month names to uppercase with moment.js

After changing the moment's locale by setting the property below:

moment.locale(chosenLocale);

It appears that everything is functioning correctly. The month names and weekday names are displayed according to the selected locale, and week numbers are calculated accurately as well.

Using the default (English) locale, I see month names such as January, February, etc., along with weekday names like Monday, Tuesday, etc. However, with the Danish locale, these names appear in lowercase. While it's simple to capitalize the first letter when formatting a basic weekday, more complex formats may present challenges where merely uppercase the first letter won't suffice (January 1st vs. 1. Januar).

The format I'm using to show the month name and day of the month is:

moment().format('dddd LL')

In Danish, I receive 7. marts 2016, but my preference is 7. Marts 2016. It's important to note that I need a solution that works for all locales, so hardcoding the month names isn't an option - or is it? I attempted the following workaround:

moment.locale(chosenLocale);
var __months = moment.months().map(function (m) { return m.toUpperCase() + "TEST"; });
moment.locale(chosenLocale, {
    months : __months
}); 

My expectation was to receive JANUARTEST for the Danish locale during testing, however, I received januartest. This suggests that the lowercase issue is being applied elsewhere within the framework. I also experimented with setting the months property to a function as per the API docs, returning the uppercase value of the cached month array, but encountered the same outcome.

Is there a viable solution to this dilemma?

Answer №1

In the Danish locale, I'm noticing that all names are lowercase for some reason.

This is actually intentional. In Danish, like in many other languages such as Spanish, French, Italian, and Russian, the names of months and weekdays are not capitalized. Each locale file in moment.js has been carefully curated by native speakers of the language. It's generally recommended not to attempt to correct capitalizations in your own code. If you spot an issue with a specific locale, feel free to open an issue on GitHub so we can consult the appropriate locale owner.

Occasionally, there have been requests for providing alternate capitalized versions for specific use cases like at the start of sentences or as column headers. However, deciding when to capitalize can vary significantly among different languages. Currently, moment does not offer these distinctions and aims for a consistent approach.

I tested your code with version 2.12.0, and it seems to work fine. You might be receiving a deprecation warning because the recommended way to modify an existing locale is to use the updateLocale method. So, consider updating your code to:

moment.updateLocale(chosenLocale, { months : __months });

Nevertheless, based on the reasons outlined earlier, I would advise against making these changes unless absolutely necessary.

Answer №2

Why not experiment with CSS:

.selector .to .lowercase .element {
  text-transform: capitalize;
}

By using this selector, it will automatically capitalize any text string.

Answer №3

To convert text to uppercase in JavaScript, simply use the .toUpperCase() method.

For example:

<span>NAME: {customerName.toUpperCase()}</span>

This will output: "NAME: JOHN DOE"

Answer №4

Encountering a similar problem in Spanish, mirroring the issue reported in French by Charles Martin. The individual responsible for translating the names of months and days into Spanish with all lowercase letters should have considered capitalizing the first letter, akin to English.

This adjustment would simplify the process of converting everything to lowercase using .toLowerCase(), if necessary.

While it's quite straightforward to convert all characters to lowercase, it's not as easy when aiming to capitalize only the initial letter of the week and month while using the .format('dddd, DD [de] MMMM') function. In such cases, resorting to an additional function to split, capitalize the first letter, and then join becomes the only viable option.

Until a permanent solution is put in place, I intend to follow the suggested workaround of dynamically updating the locale.

moment.locale('es');
var meses = 'Enero_Febrero_Marzo_Abril_Mayo_Junio_Julio_Agosto_Septiembre_Octubre_Noviembre_Diciembre'.split('_');
var semanas = 'Domingo_Lunes_Martes_Miércoles_Jueves_Viernes_Sábado'.split('_');
moment.updateLocale('es', { months : meses, weekdays : semanas });

If further modifications are required, refer to the moment-with-locales.js file. Search for hooks.defineLocale('es' to access and alter all associated properties externally.
