Angular 6 Router Transition Animation不起作用（导航栏）

Question

I am trying to implement Fade transition on my router outlet - whenever you move to a page you get fadein/out.

However it just doesn't seem to work at all, the router outlet is in the main area of the navigation bar: Stackblitz of my app

See "fadeIn.ts" for the animation See "app.nav-component" html/ts and app module for implementation

I would expect when clicking a link in the navigation the animation of transition would trigger.

I modified your fadeIn.ts a bit.

import {
    trigger,
    animate,
    transition,
    style,
    query, group
  } from '@angular/animations';

  export const fadeAnimation = trigger('fadeAnimation', [
    transition('* <=> *', [

        /* order */

        /* 1 */ query(':enter, :leave', style({ position: 'fixed', width: '100%' })

          , { optional: true }),


        /* 2 */ group([  // block executes in parallel

          query(':enter', [

            style({ transform: 'translateX(100%)' }),

            animate('0.3s ease-in-out', style({ transform: 'translateX(0%)' }))

          ], { optional: true }),

          query(':leave', [

           style({ transform: 'translateX(0%)' }),

            animate('0.3s ease-in-out', style({ transform: 'translateX(-100%)' }
          ))], { optional: true }),         

        ])

      ])
  ]);
