我有两个组件在路线更改时已经具有有效的淡入/淡出动画,以及在页面加载时从黑色背景(在CSS中完成)淡入的外部背景图像。
app.component.html
<div class="bg"></div>
<div class="bgImage"></div>
<div class="main" [@fadeAnimation]="getDepth(myOutlet)">
<router-outlet #myOutlet="outlet"></router-outlet>
</div>
app.component.ts
import { Component } from '@angular/core';
import { fadeAnimation } from './fade.animation';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss']
, animations: [fadeAnimation]
})
export class AppComponent {
title = 'app';
getDepth(outlet){
return outlet.activatedRouteData['depth'];
}
}
我也在尝试使路线更改时背景图像模糊/模糊。
这是动画服务,我的逻辑是模糊动画应被删除。
fade.animation.ts
import { trigger, animate, transition, style, query } from '@angular/animations';
export const fadeAnimation =
trigger('fadeAnimation', [
transition( '1 => 2', [
query(':enter',
[
style({ opacity: 0 })
],
{ optional: true }),
// query('.bgImage',
// [
// style({ filter: 'blur(0px)' }),
// animate('1s ease-in-out', style({ filter: 'blur(5px)' }))
// ],
// { optional: true }
// ),
query(':leave',
[
style({ opacity: 1 }),
animate('0.25s ease-in-out', style({ opacity: 0 }))
],
{ optional: true }),
query(':enter',
[
style({ opacity: 0 }),
animate('0.25s ease-in-out', style({ opacity: 1 }))
],
{ optional: true })
]),
transition( '2 => 1', [
query(':enter',
[
style({ opacity: 0 })
],
{ optional: true }),
// query('.bgImage',
// [
// style({ filter: 'blur(5px)' }),
// animate('1s ease-in-out', style({ filter: 'blur(0px)' }))
// ],
// { optional: true }
// ),
query(':leave',
[
style({ opacity: 1 }),
animate('0.25s ease-in-out', style({ opacity: 0 }))
],
{ optional: true }),
query(':enter',
[
style({ opacity: 0 }),
animate('0.25s ease-in-out', style({ opacity: 1 }))
],
{ optional: true })
])
]);

Not sure if I understand the question correctly.
Define a trigger blur.
trigger('blur', [
state('1', style({filter: 'blur(0px)'})),
state('2', style({filter: 'blur(8px)'})),
transition('1=>2', [ animate('1s')]),
transition('2=>1', [ animate('1s')])
])
And in HTML:
<div class="bgImage" [@blur]="getDepth(myOutlet)" ></div>
