我正在尝试在Angular中重新加载当前页面。
因此,当我重新加载页面时,将调用我的根组件并执行以下行:
console.log(this.router.routerState.snapshot.url)
显示“ / component-x”
然后执行以下代码行:
this.router.navigate(['/component-x]')
它不起作用,我已退出应用程序。
是否支持在Angular中导航到当前路线? 以及如何才能重新加载当前页面?
请注意,我的应用程序托管在AWS的Cloudfront上,并且我设置了规则设置,以在出现404错误(即发生页面刷新)时返回index.html,并且我遵循了有关重新加载当前路由的指南在Angular中:https://medium.com/engineering-on-the-incline/reloading-current-route-on-click-angular-5-1a1bfc740ab2
但是它仍然无法正常工作。有人可以指出我所缺少的吗?
谢谢!

您可以使用Angular路由器中的onSameUrlNavigation
:
@ngModule({
imports: [RouterModule.forRoot(routes, {onSameUrlNavigation: ‘reload’})],
exports: [RouterModule],
})
然后在您的路线上使用runGuardsAndResolvers
并将其设置为始终:
export const routes: Routes = [
{
path: 'my-path',
component: MyComponent,
children: [
{
path: '',
loadChildren: './pages/my-path/mycomponent.module#MyComponentModule',
},
],
canActivate: [AuthenticationGuard],
runGuardsAndResolvers: 'always',
}
]
通过这两个更改,您的路由器已配置。现在,您需要插入组件中的NavigationEnd
:
export class MyComponent implements OnInit, OnDestroy{
// ... your class variables here
navigationSubscription;
constructor(
// … your declarations here
private router: Router,
) {
// subscribe to the router events - storing the subscription so
// we can unsubscribe later.
this.navigationSubscription = this.router.events.subscribe((e: any) => {
// If it is a NavigationEnd event re-initalise the component
if (e instanceof NavigationEnd) {
this.initialiseMyComponent();
}
});
}
initialiseMyComponent() {
// Set default values and re-fetch any data you need.
}
ngOnDestroy() {
// avoid memory leaks here by cleaning up after ourselves. If we
// don't then we will continue to run our initialiseInvites()
// method on every navigationEnd event.
if (this.navigationSubscription) {
this.navigationSubscription.unsubscribe();
}
}
}
然后您就可以拥有重新加载功能。希望这可以帮助。不幸的是,文档在这些方面不是很清楚。
