Læs JSON-fil ved hjælp af JavaScript
JSON står for JavaScript-objektnotation . Det er en måde at organisere data i en scriptfil ved hjælp af tekst, hvilket gør det nemt at gemme og dele data.
Læsning JSON filer, uanset om de er gemt lokalt eller på en server, er afgørende for webapplikationer. I denne tutorial dækker vi tre metoder til at læse JSON-filer i JavaScript, hvilket kan være virkelig nyttigt for webudviklere.
Indholdsfortegnelse
- Hvordan læser jeg JSON-fil i JavaScript?
- Brug af fetch() API til at læse JSON-fil
- Brug af Require Module til at læse JSON-fil
- Ved at importere modulet til at læse JSON-filen
- Konklusion
BEMÆRK: JavaScript understøtter JSON internt, så det kræver ikke yderligere moduler for at importere og vise JSON. Vi skal bare importere JSON-filen og kan nemt bruge den direkte til at udføre manipulationer på den.
Hvordan læser jeg JSON-fil i JavaScript?
Tre metoder til at læse JSON-filer i JavaScript er:
Bemærk: Nedenstående JSON-fil vil blive brugt til at hente dataene.
sample.json
{ 'users':[ { 'site':'techcodeview.com', 'user': 'Shobhit' } ] } 1. Brug af fetch() API til at læse JSON-fil
metoden fetch() bruges til at læse JSON-filer (lokale eller uploadede filer). Den bruger den samme syntaks for begge filtyper.
Syntaks
fetch('JSONFilePath').then().then().catch(); Følg disse trin for at læse JSON-filen ved hjælp af appetch API-metoden:
- Opret en JSON-fil og tilføj data til den
- Åbn JavaScript-filen
- I hentemetoden videregives stien til JSON-filen
- Brug .json()-metoden til at parse dataene i JSON-format.
- Vis indholdet i konsollen.
Eksempel på læsning af JSON-fil i JavaScript:
Nedenstående kode hjælper dig med at forstå brugen af fetch()-metoden til at læse JSON-filer.
