javascript - Angular 2 : NgbModal transclude in view

Question

假设我有这样的模态模板:

<div class="modal-header">
  <h3 [innerHtml]="header"></h3>
</div>

<div class="modal-body">
  <ng-content></ng-content>
</div>

<div class="modal-footer">
</div>

我从另一个组件调用这个模态，所以:

---

    const modalRef = this.modalService.open(MobileDropdownModalComponent, {
      keyboard: false,
      backdrop: 'static'
    });

    modalRef.componentInstance.header = this.text;

如何将绑定(bind)等放入 NgbModal html 中？进入 ng-content

Answer 1

您可以从 open 方法返回的 NgbModalRef 中获取对组件实例的引用，并在那里设置绑定(bind)。

这是打开模式的方法:

open() {
   const instance = this.modalService.open(MyComponent).componentInstance;
   instance.name = 'Julia';
 }

这是将在具有一个输入绑定(bind)的模态中显示的组件

export class MyComponent {
   @Input() name: string;

   constructor() {
   }
 }

您也可以将 templateRef 作为输入传递。假设父组件有

 <ng-template #tpl>hi there</ng-template>


 export class AppComponent {
   @ViewChild('tpl') tpl: TemplateRef<any>;

  constructor(private modalService: NgbModal) {
  }

 open() {
    const instance = 
    this.modalService.open(MyComponent).componentInstance;
     instance.tpl = this.tpl;
  }
}

和我的组件:

export class MyComponentComponent {
  @Input() tpl;

  constructor(private viewContainerRef: ViewContainerRef) {
  }

  ngAfterViewInit() {
     this.viewContainerRef.createEmbeddedView(this.tpl);
  }
}
