Egnet til:

  • Velge en spesifikk måned

Eksempler

Retningslinjer

Datoer langt bak eller frem i tid

Ved valg av datoer som er langt bak eller frem i tid, bør man bruke dropdownCaption-prop med fromDate/toDate. Det lar brukeren raskere finne fram til riktig år.

Gjør
Monthpicker med select-meny
Unngå
MonthPicker uten select-meny

Returformat

Komponenten returnerer datoer som et JS Date-objekt. Husk å ta høyde for tidssone ved bruk av f.eks. ISO-format. I selve komponenten bruker vi date-fns v4 for parsing.

Standard år

Du kan bruke defaultYear-propen til å styre hvilket år som vises når månedsvelgeren åpnes. Dette er nyttig når du har en antakelse om hvilket år som er mest aktuelt.

Testing

For å få konsekvente datoer lokalt og i testmiljø må du kanskje definere en tidssone i test-rammeverket. For eksempel for Vitest settes miljøvariabelen TZ=UTC.

Tilgjengelighet

Hvis du skal bruke DatePicker med et input, anbefaler vi å bruke MonthPicker.Input sammen med useMonthpicker-hooken. Da håndteres fokus og åpning/lukking automatisk.
