Conditionally Apply router reuse strategy for angular2 routes

Question

当我导航回相同的组件时，我开始了解Sticky Routes重新附加早期的组件数据。我已经通过查看此https://www.softwarearchitekt.at/post/2016/12/02/sticky-实现了一个演示routes-in-angular-2-3-with-routereusestrategy.aspx博客https://plnkr.co/edit/KVlRi9PtPeOpvn8bECBi?p=preview ...是否可以设置应用条件，以便routerreusestrategy仅适用于少数几个组件？

You need only minor modification of the original solution: https://www.softwarearchitekt.at/post/2016/12/02/sticky-routes-in-angular-2-3-with-routereusestrategy.aspx

Add shouldDetach flag to your route:

const appRoutes: Routes = [
  { path: 'crisis-center', component: CrisisListComponent, data: { shouldDetach: true } },
  ...
];

And modify shouldDetach method in CustomReuseStrategy :

public shouldDetach(route: ActivatedRouteSnapshot): boolean {
  return route.data && (route.data as any).shouldDetach;
}
