[angular] 第1880天 请说说在Angular中如何定义路由过渡动画? #5842
Comments
在 Angular 中,定义路由过渡动画可以通过 Angular 的动画模块( 1. 安装 Angular Animations首先,确保在你的 Angular 项目中安装了 npm install @angular/animations 2. 导入动画模块在你的应用模块中导入 import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
@NgModule({
imports: [
BrowserAnimationsModule,
// 其他模块
],
// 其他配置
})
export class AppModule { } 3. 定义动画在一个单独的文件中(例如 import { trigger, transition, style, query, group, animate } from '@angular/animations';
export const slideInAnimation = trigger('routeAnimations', [
transition('* <=> *', [
// 设置初始样式
query(':enter, :leave', style({ position: 'absolute', width: '100%' }), { optional: true }),
// 离开页面的动画
query(':leave', [
style({ transform: 'translateX(0%)' }),
animate('300ms ease-in-out', style({ transform: 'translateX(-100%)' }))
], { optional: true }),
// 进入页面的动画
query(':enter', [
style({ transform: 'translateX(100%)' }),
animate('300ms ease-in-out', style({ transform: 'translateX(0%)' }))
], { optional: true })
])
]); 4. 应用动画在你的根组件(例如 import { Component } from '@angular/core';
import { RouterOutlet } from '@angular/router';
import { slideInAnimation } from './app.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'];
}
} 5. 更新模板在根组件的模板中(例如 <div [@routeAnimations]="prepareRoute(outlet)">
<router-outlet #outlet="outlet"></router-outlet>
</div> 6. 配置路由数据在路由配置中为每个路由添加动画数据: import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { HomeComponent } from './home/home.component';
import { AboutComponent } from './about/about.component';
const routes: Routes = [
{ path: '', component: HomeComponent, data: { animation: 'HomePage' } },
{ path: 'about', component: AboutComponent, data: { animation: 'AboutPage' } }
];
@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class AppRoutingModule { } 7. 运行应用现在,当你在不同路由之间导航时,你应该能够看到定义的动画效果。 总结通过上述步骤,你可以在 Angular 应用中定义和使用路由过渡动画。关键步骤包括:
这些步骤可以帮助你创建更加流畅和吸引人的用户体验。 |
