角度6-获取当前路径及其数据 [英] Angular 6 - Get current route and its data

问题描述

如何获取您所在的当前路由及其数据、子路由和父路由？

如果这是路由结构：

const routes: Routes = [
  {path: 'home', component: HomeComponent, data: {title: 'Home'}},
  {
    path: 'about', 
    component: AboutComponent, 
    data: {title: 'About'},
    children: [
      {
        path: 'company',
        component: 'CompanyComponent',
        data: {title: 'Company'}
      },
      {
        path: 'mission',
        component: 'MissionComponent',
        data: {title: 'Mission'}
      },
      ...
    ]
  },
  ...
]

如果我当前在CompanyComponent中，如何获取我当前的路线w/c是Company、获取其父w/c是关于、其数据及其同级(如任务等)？

推荐答案

@Component({...})
export class CompanyComponent implements OnInit {

constructor(
  private router: Router,
  private route: ActivatedRoute
) {}

ngOnInit() {

  // Parent:  about 
  this.route.parent.url.subscribe(url => console.log(url[0].path));

  // Current Path:  company 
  this.route.url.subscribe(url => console.log(url[0].path));

  // Data:  { title: 'Company' } 
  this.route.data.subscribe(data => console.log(data));

  // Siblings
  console.log(this.router.config);
}
}
