When a user selects a hero in the dashboard, the app should navigate to the `HeroDetailComponent` to view and edit the selected hero.
|
||||
|
||||
In the dashboard template we bound each hero's click event to the `gotoDetail` method, passing along the selected `hero` entity.
|
||||
Although the dashboard heroes are presented as button-like blocks, they should behave like anchor tags.
|
||||
When hovering over a hero block, the target URL should display in the browser status bar

1. Set a route *link parameters !{_array}*
|

1. Pass the !{_array} to the router's navigate method

Now we can see what's going on as we update the component class along the same lines as the dashboard:
|
||||
### Update the _HeroesComponent_ class.
|
||||
|
||||
1. Import the `router`
|
||||
The `HeroesComponent` navigates to the `HeroesDetailComponent` in response to a button click.
|
||||
The button's _click_ event is bound to a `gotoDetail` method that navigates _imperatively_
|
||||
by telling the router where to go.
|
||||
|
||||
This approach requires some changes to the component class:
|
||||
|
||||
1. Import the `router` from the Angular router library
|
||||
1. Inject the `router` in the constructor (along with the `HeroService`)
|
||||
1. Implement the `gotoDetail` method by calling the `router.navigate` method

||||
1. Implement `gotoDetail` by calling the `router.navigate` method

||||
with a two-part hero-detail link parameters !{_array}.

|
||||
