在 Angular2 中导入 ng2-bootstrap 模态

Importing ng2-bootstrap modal in Angular2

我正在尝试使用 ng2-bootstrap 的模式。所以我配置的一切都等于下面的例子:

import { ModalModule } from 'ng2-bootstrap/ng2-bootstrap';

@NgModule({
    bootstrap: [ AppComponent ],
    declarations: [
        AppComponent,
        ...
    ],
    imports: [
        BrowserModule,
        FormsModule,
        HttpModule,
        RouterModule.forRoot(ROUTES),
        ModalModule
    ],
    providers: [ ]
})

但是我仍然收到以下错误:

Cannot read property 'show' of undefined

分量:

import { ViewContainerRef } from '@angular/core';

@Component({
    selector: 'any-comp',
    encapsulation: ViewEncapsulation.None,
    templateUrl: './any-comp.component.html'
})
export class AnyCompComponent implements OnInit {

private viewContainerRef: ViewContainerRef;

constructor(
    private pageContentService: PageContentService,
    viewContainerRef: ViewContainerRef) {
    this.viewContainerRef = viewContainerRef;
}

模板:

<button class="btn btn-primary" (click)="lgModal.show()">Large modal</button>

<div bsModal="bsmodal" #lgmodal="bs-modal" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true" class="modal fade">
  <div class="modal-dialog modal-lg">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" (click)="lgModal.hide()" aria-label="Close" class="close"><span aria-hidden="true">×</span></button>
        <h4 class="modal-title">Large modal</h4>
      </div>
      <div class="modal-body">...</div>
    </div>
  </div>
</div>

我该如何解决这个问题?

模板变量区分大小写,在您的情况下它是 #lgmodal(小写 "m")并且您试图在点击时显示 lgModal(大写 "M") :(click)="lgModal.show()"。因此,只需更改您的模板变量,使其与 (click) 事件中的变量相匹配:#lgModal.
