NavigationCancel

An event triggered when a navigation is canceled, directly or indirectly. This can happen for several reasons including when a route guard returns false or initiates a redirect by returning a UrlTree.

      
      class NavigationCancel extends RouterEvent {
  constructor(id: number, url: string, reason: string, code?: NavigationCancellationCode)
  type: EventType.NavigationCancel
  reason: string
  code?: NavigationCancellationCode
  toString(): string

  // inherited from router/RouterEvent
  constructor(id: number, url: string)
  id: number
  url: string
}
