HTML:

<button class="btn btn-primary" type="button" routerLink="/add-record">Add Record</button>
</div>
Ich brauche die "Back Squat"
Zeichenfolge in das ersetzen Komponente mit der ngModel chartFilter
, aber ich bin mir nicht sicher, wie man einen dynamisch ändernden Wert in ein for übergeben wird Schleife. Der Wert ändert sich, wenn ein neuer Artikel über das Menü <select>
ausgewählt wird.
ersetzen Sie die '" Back Squat "' mit? – Aravind
this.chartFilter –
