Angular 2.0 和Modal模态对话框

• Angular 2及以上
• bootstrap css(保留动画)
• NO JQuery个
• NO bootstrap.js
• 支持custom modal content(就像接受的答案一样)
• 最近增加了对multiple modals on top of each other的支持.

@Component({
  selector: 'app-component',
  template: `
  <button type="button" (click)="modal.show()">test</button>
  <app-modal #modal>
    <div class="app-modal-header">
      header
    </div>
    <div class="app-modal-body">
      Whatever content you like, form fields, anything
    </div>
    <div class="app-modal-footer">
      <button type="button" class="btn btn-default" (click)="modal.hide()">Close</button>
      <button type="button" class="btn btn-primary">Save changes</button>
    </div>
  </app-modal>
  `
})
export class AppComponent {
}

@Component({
  selector: 'app-modal',
  template: `
  <div (click)="onContainerClicked($event)" class="modal fade" tabindex="-1" [ngClass]="{'in': visibleAnimate}"
       [ngStyle]="{'display': visible ? 'block' : 'none', 'opacity': visibleAnimate ? 1 : 0}">
    <div class="modal-dialog">
      <div class="modal-content">
        <div class="modal-header">
          <ng-content select=".app-modal-header"></ng-content>
        </div>
        <div class="modal-body">
          <ng-content select=".app-modal-body"></ng-content>
        </div>
        <div class="modal-footer">
          <ng-content select=".app-modal-footer"></ng-content>
        </div>
      </div>
    </div>
  </div>
  `
})
export class ModalComponent {

  public visible = false;
  public visibleAnimate = false;

  public show(): void {
    this.visible = true;
    setTimeout(() => this.visibleAnimate = true, 100);
  }

  public hide(): void {
    this.visibleAnimate = false;
    setTimeout(() => this.visible = false, 300);
  }

  public onContainerClicked(event: MouseEvent): void {
    if ((<HTMLElement>event.target).classList.contains('modal')) {
      this.hide();
    }
  }
}

To show the backdrop，您将需要类似这样的CSS:

.modal {
  background: rgba(0,0,0,0.6);
}

The example now allows for multiple modals at the same time.(参见onContainerClicked()法).

For Bootstrap 4 css users，您需要做1个小更改(因为CSS类名是从Bootstrap 3更新的).这一行: [ngClass]="{'in': visibleAnimate}"应更改为: [ngClass]="{'show': visibleAnimate}"
