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;
如何使用绑定等将NgbModal html放入?进入ng-content
解决方法
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binging.
这是打开模态的方法:
open() { const instance = this.modalService.open(MyComponent).componentInstance; instance.name = 'Julia'; }
这里是将使用一个输入绑定在模态中显示的组件
export class MyComponent { @Input() name: string; constructor() { } }
===
您也可以传递templateRef作为输入.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MyComponent:
export class MyComponentComponent { @Input() tpl; constructor(private viewContainerRef: ViewContainerRef) { } ngAfterViewInit() { this.viewContainerRef.createEmbeddedView(this.tpl); } }
