[javascript] Load json from local file with http.get() in angular 2

I you want to put the response of the request in the navItems. Because http.get() return an observable you will have to subscribe to it.

Look at this example:

_x000D_
_x000D_
// version without map_x000D_
this.http.get("../data/navItems.json")_x000D_
    .subscribe((success) => {_x000D_
      this.navItems = success.json();          _x000D_
    });_x000D_
_x000D_
// with map_x000D_
import 'rxjs/add/operator/map'_x000D_
this.http.get("../data/navItems.json")_x000D_
    .map((data) => {_x000D_
      return data.json();_x000D_
    })_x000D_
    .subscribe((success) => {_x000D_
      this.navItems = success;          _x000D_
    });
_x000D_
_x000D_
_x000D_
