what happens and how to get the child that is inside the and I need to get the reference to the example-form-container? I am not getting it on the afterViewInit at all! just the top level

[@AyyazTech]

To access a child component that is inside an , you need to use the @ViewChild decorator in combination with the {read: TemplateRef} option. Here's how you can do it:
In your parent component's template, add a template reference variable to the :
In your parent component's TypeScript file, use @ViewChild with the {read: TemplateRef} option: @ViewChild('myTemplate', {read: TemplateRef}) myTemplate!: TemplateRef;
In the ngAfterViewInit lifecycle hook, you can access the template reference: ngAfterViewInit() { console.log(this.myTemplate); }
Now you have access to the reference. To get the example-form-container, you need to create an instance of the template using ViewContainerRef and then query for the child component within that instance.
Inject ViewContainerRef in your component's constructor: constructor(private viewContainerRef: ViewContainerRef) {}
Create an instance of the template in ngAfterViewInit: ngAfterViewInit() { const templateInstance = this.viewContainerRef.createEmbeddedView(this.myTemplate); const exampleFormContainer = templateInstance.rootNodes[0].querySelector('example-form-container'); console.log(exampleFormContainer); }
This way, you can access the example-form-container within the .

@@AyyazTech thank you my issue is the ExpressionChangedAfterItHasBeenCheckedError, on the parent page where the VIewChild contains the form that is passed to the child within template as @Input() I can't figure out how to solve it.

sir how can i use angular 17 aos animation

[@AyyazTech]

Angular 17 does not exist as of my knowledge cutoff date of August 2023. The latest stable version of Angular is Angular 16. However, the concepts of animations in Angular have remained relatively consistent across versions.
To use animations in Angular, you can follow these steps:
1. Import the necessary animation functions from @angular/animations:
import { trigger, state, style, animate, transition } from '@angular/animations';
2. Define an animation trigger in your component's metadata using the @Component decorator:
@Component({
selector: 'app-example',
templateUrl: './example.component.html',
styleUrls: ['./example.component.css'],
animations: [
trigger('myAnimation', [
state('start', style({
opacity: 0
})),
state('end', style({
opacity: 1
})),
transition('start => end', [
animate('1s')
])
])
]
})
3. In your component's template, apply the animation trigger to an element using the [@triggerName] syntax:
4. In your component's TypeScript file, control the animation state by assigning values to the bound property:
myAnimationState = 'start';
toggleAnimation() {
this.myAnimationState = this.myAnimationState === 'start' ? 'end' : 'start';
}
These are the basic steps to get started with animations in Angular. You can define more complex animations with multiple states, transitions, and keyframes based on your requirements.
Remember to import the BrowserAnimationsModule in your app module for animations to work:
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
@NgModule({
imports: [BrowserAnimationsModule]
})
I hope this helps you get started with animations in Angular. Let me know if you have any further questions!
