Let's say we have a component called TopComponent with a template like this:
<ng-template #top>
<inner-selector #inner></inner-selector>
</ng-template>
It's code is simple:
//... imports ...
@Component({
// selector, styles etc
})
export class TopComponent implements AfterViewInit {
@ViewChild('top') topComp : NgbModal;
// NgbModal is a type provided by some 3rd-party library
// I can't modify it
ngAfterViewInit() {
// let's access the #inner component from here
}
}
I can access the #top component using this code:
@ViewChild('top') topComponent: TopComponent;
How can I access the #inner component from the same class?
I tried using @ContentChild('inner') but still getting undefined.
PS. I know I can create another component, use it instead of <ng-template> and access all the necessary children from it. But can this be avoided somehow?
Use descendants @ViewChild('inner', {descendants: true}) inner: InnerSelector;
here is fill code: https://plnkr.co/edit/MtVhHuAtPXZzC7GLOidF?p=preview
@Component({
selector: 'inner-selector',
template:'inner-selector here'
})
export class InnerSelector {
myVar = 0;
}
@Component({
selector: 'my-app',
template: `
<div>
<ng-template #top>
<inner-selector #inner></inner-selector>
</ng-template>
<ng-container [ngTemplateOutlet]="top"></ng-container>
</div>
`,
})
export class App {
@ViewChild('inner', {descendants: true}) inner: InnerSelector;
constructor() {
this.name = `Angular! v${VERSION.full}`
}
ngAfterViewInit() {
console.log(this.inner);
}
}
