Der Input-Typ File erzeugt ein Eingabefeld für zum Beispiel Uploads. Es können eine oder auch mehrere Dateien ausgewählt werden.
Konstruktion
Code
<kol-input-file _label="Bild hochladen" _accept="image/png, image/jpeg, application/pdf" _icons='{"right": "codicon codicon-device-camera"}'></kol-input-file>
Beispiel
Verwendung
Geben Sie über das Attribut _accept an, welche Dateitypen zur Auswahl erlaubt sind. Wird das Attribut nicht oder leer übergeben, sind alle Dateitypen erlaubt. Mögliche Werte und weitere Informationen erhalten Sie im
Best practices
- Achten sie darauf
idundnamekorrekt zu setzen, damit die Daten beim Formular Absenden mitgesendet werden. - Lassen Sie nur die Dateitypen zum Upload zu, die für die Programmausführung benötigt werden. Eine fehlende Einschränkung der hochladbaren Dateitypen kann ein erhebliches Sicherheitsrisiko sein.
- Begrenzen Sie die Größe der Dateien, die Sie zum Upload zulassen möchten.
