Is there an angular event which will be triggered when all the Angular2 components have finished rendering?
For jQuery, we can use
$(function(){ ... })
However, with Angular2, when the domready event is triggered, the html contains angular component tags only. And after each component finished rendering, the domready event will be triggered again & again.
What we need is a final event when all the angular components have finished rendering.
回答1:
Have you tried ngAfterViewInit on the root AppComponent? I'm sure all the components have been rendered by then. This is a hook that angular calls after it creates all the component's child views.
回答2:
you may check ngAfterViewInit applied on the root component.
ngAfterViewInit Respond after Angular initializes the component's views and child views. Called once after the first ngAfterContentChecked.

Hope this helps!!
