要解决Angular基于路由的动画中嵌套路由的问题,可以使用以下代码示例:
首先,确保已经正确导入了所需的Angular模块和依赖项。
app.module.ts:
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { AppComponent } from './app.component';
import { HomeComponent } from './home/home.component';
import { AboutComponent } from './about/about.component';
import { ContactComponent } from './contact/contact.component';
const routes: Routes = [
{
path: '',
component: HomeComponent,
data: { animation: 'home' }
},
{
path: 'about',
component: AboutComponent,
data: { animation: 'about' }
},
{
path: 'contact',
component: ContactComponent,
data: { animation: 'contact' }
},
{
path: 'about/:id',
component: AboutComponent,
data: { animation: 'aboutWithId' }
}
];
@NgModule({
declarations: [
AppComponent,
HomeComponent,
AboutComponent,
ContactComponent
],
imports: [
BrowserModule,
BrowserAnimationsModule,
RouterModule.forRoot(routes)
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
接下来,创建一个动画服务来定义路由动画。
animations.ts:
import { trigger, transition, style, query, group, animateChild, animate } from '@angular/animations';
export const slideInAnimation =
trigger('routeAnimations', [
transition('home <=> about, contact <=> aboutWithId', [
style({ position: 'relative' }),
query(':enter, :leave', [
style({
position: 'absolute',
top: 0,
left: 0,
width: '100%'
})
]),
query(':enter', [
style({ left: '-100%' })
]),
group([
query(':leave', [
animate('300ms ease-out', style({ left: '100%' }))
]),
query(':enter', [
animate('300ms ease-out', style({ left: '0%' }))
])
]),
query(':enter', animateChild())
]),
transition('* <=> contact', [
style({ position: 'relative' }),
query(':enter, :leave', [
style({
position: 'absolute',
top: 0,
left: 0,
width: '100%'
})
]),
query(':enter', [
style({ left: '-100%' })
]),
group([
query(':leave', [
animate('200ms ease-out', style({ left: '100%' }))
]),
query(':enter', [
animate('300ms ease-out', style({ left: '0%' }))
])
]),
query(':enter', animateChild())
])
]);
在动画服务中,我们使用了不同的动画过渡效果,具体取决于路由间的切换。
最后,在根组件中应用动画服务。
app.component.html:
app.component.ts:
import { Component } from '@angular/core';
import { RouterOutlet } from '@angular/router';
import { slideInAnimation } from './animations';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css'],
animations: [slideInAnimation]
})
export class AppComponent {
prepareRoute(outlet: RouterOutlet) {
return outlet && outlet.activatedRouteData && outlet.activatedRouteData['animation'];
}
}
现在,当你导航到不同的路由时,你应该能够看到基于路由的动画效果。
请注意,以上示例仅提供了一个基本的解决方案,你可以根据你的需求进行自定义和扩展。
