<div class="button" click="routeWithData()">Pass data and route</div>

在angular 6或其他版本中，我希望最简单的方法是用你想要传递的数据量定义你的路径

{path: 'detailView/:id', component: DetailedViewComponent}

正如你可以从我的路由定义中看到的，我已经添加了/:id来支持我想通过路由器导航传递给组件的数据。因此，您的代码将看起来像

<a class="btn btn-white-view" [routerLink]="[ '/detailView',list.id]">view</a>

为了读取组件上的id，只需导入ActivatedRoute like

import { ActivatedRoute } from '@angular/router'

在ngOnInit上是你检索数据的地方

ngOnInit() {
       this.sub = this.route.params.subscribe(params => {
        this.id = params['id'];
        });
        console.log(this.id);
      }

使用共享服务使用自定义索引存储数据。然后用queryParam发送自定义索引。这种方法更加灵活。

// component-a : typeScript :
constructor( private DataCollector: DataCollectorService ) {}

ngOnInit() {
    this.DataCollector['someDataIndex'] = data;
}

// component-a : html :
<a routerLink="/target-page" 
   [queryParams]="{index: 'someDataIndex'}"></a>

.

// component-b : typeScript :
public data;

constructor( private DataCollector: DataCollectorService ) {}

ngOnInit() {
    this.route.queryParams.subscribe(
        (queryParams: Params) => {
            this.data = this.DataCollector[queryParams['index']];
        }
    );
}

ActiveRoute的解决方案(如果你想通过路由传递对象-使用JSON.stringfy/JSON.parse):

发送前准备对象:

export class AdminUserListComponent {

  users : User[];

  constructor( private router : Router) { }

  modifyUser(i) {

    let navigationExtras: NavigationExtras = {
      queryParams: {
          "user": JSON.stringify(this.users[i])
      }
    };

    this.router.navigate(["admin/user/edit"],  navigationExtras);
  }

}

在目标组件中接收对象:

export class AdminUserEditComponent  {

  userWithRole: UserWithRole;      

  constructor( private route: ActivatedRoute) {}

  ngOnInit(): void {
    super.ngOnInit();

      this.route.queryParams.subscribe(params => {
        this.userWithRole.user = JSON.parse(params["user"]);
      });
  }

}

更新4.0.0

更多细节请参见Angular Angular Router -在导航前获取数据。

原始

使用服务是正确的选择。在路由参数中，您应该只传递希望在浏览器URL栏中反映的数据。

参见Angular Cookbook组件通信-双向服务。

RC.4附带的路由器重新引入了数据

constructor(private route: ActivatedRoute) {}

const routes: RouterConfig = [
  {path: '', redirectTo: '/heroes', pathMatch: 'full'},
  {path: 'heroes', component: HeroDetailComponent, data: {some_data: 'some value'}}
];

class HeroDetailComponent {
  ngOnInit() {
    this.sub = this.route
      .data
      .subscribe(v => console.log(v));
  }

  ngOnDestroy() {
    this.sub.unsubscribe();
  }
}

参见Plunker。

说你有

component1.ts component1.html

您希望将数据传递给component2.ts。

in component1.ts is a variable with data say //component1.ts item={name:"Nelson", bankAccount:"1 million dollars"} //component1.html //the line routerLink="/meter-readings/{{item.meterReadingId}}" has nothing to //do with this , replace that with the url you are navigating to <a mat-button [queryParams]="{ params: item | json}" routerLink="/meter-readings/{{item.meterReadingId}}" routerLinkActive="router-link-active"> View </a> //component2.ts import { ActivatedRoute} from "@angular/router"; import 'rxjs/add/operator/filter'; /*class name etc and class boiler plate */ data:any //will hold our final object that we passed constructor( private route: ActivatedRoute, ) {} ngOnInit() { this.route.queryParams .filter(params => params.reading) .subscribe(params => { console.log(params); // DATA WILL BE A JSON STRING- WE PARSE TO GET BACK OUR //OBJECT this.data = JSON.parse(params.item) ; console.log(this.data,'PASSED DATA'); //Gives {name:"Nelson", bankAccount:"1 //million dollars"} }); }

一些超级聪明的人(tmburnell)(不是我)建议重写路由数据:

let route = this.router.config.find(r => r.path === '/path');
route.data = { entity: 'entity' };
this.router.navigateByUrl('/path');

正如你在评论中看到的。

我希望有人会觉得这有用
