Tips for implementing index values in typescript within an Angular Material Table

<mat-cell *matCellDef="let element; let i index">{{ element.patientName }}<input type="hidden" [(ngModel)]="index" value={{i}}/></mat-cell>

I created an index variable to access the value in the typescript file and attempted to console.log(index), but it returned undefined.

export class DashboardComponent implements OnInit, OnDestroy {

index: number;
  
constructor(){}

console.log(index);
}

Answer №1

transform i into index by replacing it with index as i. Documentation provided here

https://angular.io/api/common/NgForOf

If you want to use it within .ts file, add the following line inside ngfor. Assign each i to the store function upon clicking a button. [ Make sure to write a store function in your typescript beforehand ]

<button (click)="store(i)"> </button>

Your project may not require a button, feel free to use any element you prefer, but ensure you include (event) to pass values in typescript. Events include: (click) / (change) / (use any event you need)
