Angular 5动画特定过渡

Question

所以我的问题是我想在页面之间指定一个特定的动画。

当我点击一个导航到特定URL的按钮（我在第1页并导航到第2页）http：// localhost：4200 / page2时，我想做一种动画。然后，如果我在page1上并且想要goBack（），当我返回主页http：// localhost：4200时，我想要一个不同的动画。

但是由于：离开过渡选项我无法实现我的目标，因为我只有一种类型的动画。我的想法是做那样的事情：

trigger('zoomAndFade', [
  transition( 'page1=> page2', [
    query('.content', [
      style({fontSize: '1em', opacity: 1}),
      animate('2s ease-in-out', style({fontSize: '1.5em', opacity: 0}))
    ])
  ])

trigger('fade', [
  transition( 'page2=>page1', [
    query('.content', [
      style({opacity: 1}),
      animate('2s ease-in-out', style({opacity: 0}))
    ])
  ])

但是如何指定动画页面的状态？

Answer 1

这个有可能。只需将此getState方法添加到app.component即可。

app.component.ts

export class AppComponent {
    getState(outlet) {
        return outlet.activatedRouteData.state;
    }
}

在模板中，您需要在更改事件上获取路由器的新状态。

app.component.html

<main [@routerTransition]="getState(o)">
    <router-outlet #o="outlet"></router-outlet>
</main>

现在，您组件中的动画可以区分您的页面。

然后你可以进行过渡

trigger("routerTransition", [
    transition("* => settings", slideLeft),
    transition("settings => *", slideRight),
])

但是你的路由器需要传输数据

{
    path: "settings",
    component: SettingsComponent,
    data: { state: "settings" }
}

而你的动画现在可以有：输入和：离开

query(":enter",
    [
        style({
            transform: "translateX(100%)"
        }),
        animate("0.4s ease-in-out",
            style({
                transform: "translateX(0%)"
            })
        )
    ], {
        optional: true
    }
),
query(":leave",
    [
        style({
            transform: "translateX(0%)"
        }),
        animate("0.4s ease-in-out",
            style({
                transform: "translateX(-100%)"
            })
        )
    ], {
        optional: true
    })
