Angular & Bootstrap Modal

I have a data table, with a button that opens a Modal (Bootstrap Modal) for each table row.

I would like that when I open a one row modal, I get the data from that row.

it works with "console.log (this.array[index])". And also when I open the Modal, it always shows me the data of the first row of the table.

I think I'm missing an index parameter in the modal.

Thank you in advance for your help.

My TS File :

    export class ListeDevisComponent implements OnInit {
  listeDevis = [];

  constructor(private listeDevisService: ListeDevisService) {}

  ngOnInit() {
    this.listeDevisService.getListeDevis().subscribe(
      (data: any) => {
        this.listeDevis = data;
      },
      (error) => {
        console.error(error);
      },
      () => {
        console.log("Liste Devis Success");
      }
    );
  }

  voirIndexDevis(index) {
    console.log(this.listeDevis[index]);
  }
}

My HTML File :

    <table class="table">
  <thead class="thead-dark">
    <tr>
      <th scope="col">ID Devis</th>
      <th scope="col">Date Devis</th>
      <th scope="col">Actions</th>
      <th scope="col">Nom Complet</th>
      <th scope="col">Contact</th>
    </tr>
  </thead>
  <tbody>
    <tr *ngFor="let liste of listeDevis; let i = index">
      <td>{{ liste.idDevis }}</td>
      <td>{{ liste.dateDevis }}</td>
      <td>
        <button
          class="btn btn-primary"
          data-toggle="modal"
          data-target="#exampleModal"
          (click)="voirIndexDevis(i)"
        >
          Test Modal Actions
        </button>
      </td>
      <td>{{ liste.nom }} {{ liste.prenom }}</td>
      <td>{{ liste.email }}</td>
    </tr>
  </tbody>
</table>

To get the row data, pass liste instead of i:

(click)="voirIndexDevis(liste)"

Then, set the current list item in the component file:

export class ListeDevisComponent implements OnInit {
  listeDevis = [];
  currentListe;

  constructor(private listeDevisService: ListeDevisService) {}

  // ngOnInit removed for brevity

  voirIndexDevis(liste) {
    this.currentListe = liste;
  }
}

Then adjust the modal, removing the *ngFor and adding the safe navigation operator to each instance of currentListe.prop:

<!-- Modal -->
<div
  class="modal fade"
  id="exampleModal"
  tabindex="-1"
  aria-labelledby="exampleModalLabel"
  aria-hidden="true"

    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Liste Devis</h5>
        <button
          type="button"
          class="close"
          data-dismiss="modal"
          aria-label="Close"
        >
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        <div class="row">
          <div class="col-lg-3 col-12 border">
            <h5>Type Installation :</h5>

          Fermer
        </button>
      </div>
    </div>
  </div>
</div>

If the safe navigation operator (currentListe?.prop) does not work, you could also use an ngIf:

<div class="row" *ngIf="currentListe">
<!-- row data -->
</div>

Alternative Solution

Because we all love options, you can also control the modal manually. First, remove the logic that connects the row buttons to the modal:

<button
  class="btn btn-primary"
  (click)="voirIndexDevis(liste)"
>
  Test Modal Actions
</button>

Then add logic to the component file to show/hide the modal:

export class ListeDevisComponent implements OnInit {
  listeDevis = [];
  currentListe;
  showModal: boolean = false;

  constructor(private listeDevisService: ListeDevisService) {}

  // ngOnInit removed for brevity

  voirIndexDevis(liste) {
    this.currentListe = liste;
    this.showModal = true;
  }

  hideModal() {
    this.showModal = false;
  }
}

Then update the modal show/hide logic by adding an *ngIf to the outer div and updating the close button in the upper-right corner and the footer button to call hideModal() when clicked:

<div
  *ngIf="showModal"
  class="modal fade"
  id="exampleModal"
  tabindex="-1"
  aria-labelledby="exampleModalLabel"
  aria-hidden="true"
>
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Liste Devis</h5>
        <button
          type="button"
          class="close"
          onclick="hideModal()"
          aria-label="Close"
        >
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        <!-- hide modal body for brevity -->
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" onclick="hideModal()">
          Fermer
        </button>
      </div>
    </div>
  </div>
</div>

At the voirIndexDevis function you have to do the same event into the service file but this time only receive the listeDevis with the index you sent. But i advise you to create a new variable like Devis and paste the data from that event so that variable only contain the one that you click.
