angular 9，我可以使用canDeactivate路由到其他地方吗？

import { CanDeactivate } from '@angular/router';

export interface CanComponentDeactivate {
  canDeactivate: () => boolean | Promise<boolean> | Observable<boolean>;
}

export class CanDeactivateGuard implements CanDeactivate<CanComponentDeactivate> {
  canDeactivate(
    component: CanComponentDeactivate,
    currentRoute: ActivatedRouteSnapshot,
    currentState: RouterStateSnapshot,
    nextState?: RouterStateSnapshot
  ): boolean | Promise<boolean> | Observable<boolean> {
    return component.canDeactivate ? component.canDeactivate() : true;
  }
}

// 在路由配置中使用守卫
{
  path: 'example',
  component: ExampleComponent,
  canDeactivate: [CanDeactivateGuard]
}

import { CanComponentDeactivate } from './can-deactivate.guard';

export class ExampleComponent implements CanComponentDeactivate {
  // ...

  canDeactivate(): boolean | Promise<boolean> | Observable<boolean> {
    // 在这里执行你的逻辑，返回一个布尔值、Promise<boolean>或Observable<boolean>
    return confirm('确定要离开吗？');
  }
}
