这是一个非常简单的例子。
我如何制作这个动画?
说明是:
Mobile menu, show/hide based on mobile menu state.
Entering: "duration-200 ease-out"
From: "opacity-0 scale-95"
To: "opacity-100 scale-100"
Leaving: "duration-100 ease-in"
From: "opacity-100 scale-100"
To: "opacity-0 scale-95"

我不知道如何将其转换为有角度的动画
以下是我将遵循的方法。
BrowserAnimationsModule@NgModule({
imports: [ BrowserModule, BrowserAnimationsModule, ... ],
...
})

@Component装饰器下创建animations数组,如下所示@Component({
,,,,
animations: [
trigger("openClose", [
// ...
state(
"open",
style({
opacity: 1,
transform: "scale(1, 1)"
})
),
state(
"closed",
style({
opacity: 0,
transform: "scale(0.95, 0.95)"
})
),
transition("open => closed", [animate("100ms ease-in")]),
transition("closed => open", [animate("200ms ease-out")])
])
]
})

在我们下面包含的动画数组中
trigger("openClose", [ ...])它定义了触发器的名称。这将在 HTML 模板中用于绑定到 dom 元素
使用定义 2 个状态state('stateName'在上面的示例中,状态名称是open和closed
在状态下我们使用定义样式style({ ... })
我们最终使用 定义转换transition(...)。这将定义时间和动画风格
有关动画的更多信息角度动画
get openCloseTrigger() {
return this.mobileMenuOpen ? "open" : "closed";
}

一切都应该准备就绪,并且您的菜单应该根据需要设置动画
在导航时关闭浏览器
我们可以利用NavigationEnd事件来实现此功能。当用户位于特定页面上时,他们不会离开该页面,因此不会NavigationEnd。菜单将保持打开状态,但当他们导航到另一个页面时,NavigationEnd将调用事件并且菜单将关闭
这就是方法
constructor(private router: Router) {}
navigationEnd$ = this.router.events.pipe(
filter(event => event instanceof NavigationEnd),
tap(() => (this.mobileMenuOpen = false))
);
ngOnInit() {
this.navigationEnd$.subscribe();
}
