我有以下代码,我想在进入和离开时应用于组件:
animations: [
trigger('visibilityChanged', [
state('in', style({opacity: 1})),
transition('void => *', [
style({opacity: 1}),
animate(100)
]),
transition('* => void', [
animate(100, style({opacity: 0}))
])
])
]
这几乎与Angular docs provide的示例完全相同,但由于某种原因,当从void => *
状态开始时,没有淡入。
我也在live examples页面尝试过此操作但没有成功。
有什么想法吗?

animations: [
trigger('visibilityChanged', [
state('in', style({
opacity: 0
})),
state('out', style({
opacity: 1
})),
transition('in => out', animate('100ms ease-in')),
transition('out => in', animate('100ms ease-out'))
])
]

我建议您结帐 ng-animate ,因为它具有许多开箱即用的动画,这些动画很容易实现,但是如果想要的代码没有适合您目的的库,请使用以下代码:
import { trigger, animate, transition, style, state } from '@angular/animations';
export const simpleFadeAnimation = trigger('simpleFadeAnimation', [
// the "in" style determines the "resting" state of the element when it is visible.
state('in', style({opacity: 1})),
// fade in when created. this could also be written as transition('void => *')
transition(':enter', [
style({opacity: 0}),
animate(1000 )
]),
// fade out when destroyed. this could also be written as transition('void => *')
transition(':leave',
animate(1000, style({opacity: 0})))
]);
或者如果要通过“ X”轴进行平移,请使用以下方法:
import { trigger, animate, transition, style, group, query } from '@angular/animations';
export const slideInAnimation = trigger('slideInAnimation', [
// Transition between any two states
transition('* <=> *', [
// Events to apply
// Defined style and animation function to apply
// Config object with optional set to true to handle when element not yet added to the DOM
query(':enter, :leave', style({ position: 'fixed', width: '100%', zIndex: 2 }), { optional: true }),
// group block executes in parallel
group([
query(':enter', [
style({ transform: 'translateX(100%)' }),
animate('0.7s ease-out', style({ transform: 'translateX(0%)' }))
], { optional: true }),
query(':leave', [
style({ transform: 'translateX(0%)' }),
animate('0.7s ease-out', style({ transform: 'translateX(-100%)' }))
], { optional: true })
])
])
]);
之后,您需要将其导入到 .ts 文件中的 @Component 装饰器中。而且,如果您想通过应用程序内部的所有组件共享它,请使用以下命令:
<div [@slideInAnimation]="o.isActivated ? o.activatedRoute : ''">
<router-outlet #o="outlet"></router-outlet>
</div>
