我有2条路线:
export const appRoutes: Route[] = [
{
path: 'page1',
component: Page1Component,
data: {
animation: 'page1'
}
},
{
path: 'page2',
component: Page2Component,
data: {
animation: 'page2'
}
},
];
我的路线动画:
export const routeStateTrigger = trigger('routeState', [
transition('* => *', [
query(':enter', [
style({ position: 'absolute', opacity: 0 })
], { optional: true }),
query(':leave', [
animate(300, style({ opacity: 0 }))
], { optional: true }),
query(':enter', [
style({ position: 'relative', opacity: 0 }),
animate(300, style({ display: 'visible', opacity: 1 }))
], { optional: true })
])
]);
我的路由器插座:
<div [@routeState]="getAnimationData(routerOutlet)">
<router-outlet #routerOutlet="outlet"></router-outlet>
</div>
和getAnimationData方法:
getAnimationData(routerOutlet: RouterOutlet) {
const routeData = routerOutlet.activatedRouteData['animation'];
return routeData ? routeData : 'rootPage';
}
这很好,除了页面转换是分两个步骤进行(顺序):
我想要的是page1的消失应该在page2出现的同时发生,过渡应该同时发生。
问题:
我想防止页面1或页面2的内容的临时大小调整。
说明:
[使用group()设置动画以使其同时消失时,并将位置临时设置为“绝对”,然后调整内容大小(因为内容宽度为100%,并且当容器尺寸更改时,内容也随之更改)。
我尝试过使用z-index:
position: 'relative', 'z-index': 1
但是那没有用,它仍然在进入页面堆叠在离开页面之下。
对此是否有好的解决方案?
尝试这个简单的过渡。
export const routeStateTrigger =
// trigger name for attaching this animation to an element using the [@triggerName] syntax
trigger('routeState', [
// route 'enter and leave (<=>)' transition
transition('*<=>*', [
// css styles at start of transition
style({ opacity: 0 }),
// animation and styles at end of transition
animate('0.4s', style({ opacity: 1 }))
]),
]);
我终于使它起作用了:
export const routeStateTrigger = trigger('routeState', [
transition('* => *', [
query(':enter', [
style({ opacity: 0 })
], { optional: true }
),
group([
query(':leave', [
animate(300, style({ opacity: 0 }))
],
{ optional: true }
),
query(':enter', [
style({ opacity: 0 }),
animate(300, style({ opacity: 1 }))
],
{ optional: true }
)
])
])
]);
此CSS选择器完成了技巧:
/deep/ router-outlet~* {
position: absolute;
width: 100%;
height: 100%;
}
因为我使用的是页脚,所以绝对位置绝对不理想。这是我所做的:
// animation.ts
export const fadeAnimation =
trigger('fadeAnimation', [
transition('* => *', [
query(':enter',
[
/* Modified the css here so to push the new element on top while its transitioning */
style({opacity: 0, position: 'absolute', top: 0, left: 0, width: '100vw', background:'#fff', height: '100vh', 'z-index' : 10})
],
{optional: true}
),
query(':leave',
[
style({opacity: 1}),
animate('0.5s', style({opacity: 0}))
],
{optional: true}
),
query(':enter',
[
style({opacity: 0}),
animate('0.5s', style({opacity: 1}))
],
{optional: true}
)
])
]);
// mystyle.scsss
:host {
main {
position: relative;
}
}
