How to call scrollIntoView on an element in angular 2+
First add a template reference variable in the element (the #myElem
):
<p #myElem>Scroll to here!</p>
Then create a property in the component with attribute ViewChild
, and call .nativeElement.scrollIntoView
on it:
export class MyComponent {
@ViewChild("myElem") MyProp: ElementRef;
ngOnInit() {
this.MyProp.nativeElement.scrollIntoView({ behavior: "smooth", block: "start" });
}
}
You could intercept the NavigationEnd event
private scrollToSectionHook() {
this.router.events.subscribe(event => {
if (event instanceof NavigationEnd) {
const tree = this.router.parseUrl(this.router.url);
if (tree.fragment) {
const element = document.querySelector('#' + tree.fragment);
if (element) {
setTimeout(() => {
element.scrollIntoView({behavior: 'smooth', block: 'start', inline: 'nearest'});
}, 500 );
}
}
}
});
}
You can achieve the same animated scroll to the element in Angular 2+, simply pass the element on click, like so:
<button mat-fab (click)="scroll(target)">
<i class="material-icons">
arrow_drop_down
</i>
</button>
<div #target></div>
public scroll(element: any) {
element.scrollIntoView({ behavior: 'smooth' });
}
