How to make Angular 2 remember scroll position?

问题

I'm on page 1, I scroll halfway through the page and then click a link that brings me to page 2 through the Angular router. When I hit the "back" button, I'd like page 1 to be scrolled halfway down, just like it was before I left that page.

What is the easiest way to do that?

回答1:

Save to localStorage scroll position in ngOnDestroy(), and restore it in ngOnInit()
