Angular&Bootstrap Modal

问题描述

我有一个数据表,带有一个按钮,用于为每个表行打开一个模态(Bootstrap Modal)。

当我打开一行模式时,我希望从那一行获取数据。

它与"console.log (this.array[index])"一起使用。而且,当我打开Modal时,它总是向我显示表第一行的数据。

我认为我在模态中缺少索引参数。

预先感谢您的帮助。

我的TS文件

    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]);
  }
}

我的HTML文件

    <table class="table">
  <thead class="thead-dark">
    <tr>
      <th scope="col">ID Devis</th>
      <th scope="col">Date Devis</th>

      <th scope="col">Nom Complet</th>
      <th scope="col">Contact</th>

解决方法

要获取行数据,请传递liste而不是i

(click)="voirIndexDevis(liste)"

然后,在组件文件中设置当前列表项:

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

  constructor(private listeDevisService: ListeDevisService) {}

  // ngOnInit removed for brevity

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

然后调整模态,删除*ngFor并将安全导航运算符添加到currentListe.prop的每个实例中:

  </div>
</div>

如果安全导航操作符(currentListe?.prop)不起作用,您还可以使用ngIf:

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

替代解决方案

由于我们都喜欢选项,因此您也可以手动控制模式。首先,删除将行按钮连接到模式的逻辑:

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

然后将逻辑添加到组件文件以显示/隐藏模态:

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;
  }
}

然后通过将*ngIf添加到外部div并更新右上角的关闭按钮和页脚按钮以在发生以下情况时调用hideModal()来更新模式显示/隐藏逻辑点击了:

<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>
,

voirIndexDevis函数中,您必须对服务文件执行相同的事件,但是这次仅收到带有发送的索引的listeDevis。但我建议您创建一个像Devis这样的新变量,并粘贴该事件中的数据,以便该变量仅包含您单击的变量。
