Redirect within component Angular 2
提问by ThreeAccents
I have a simple method that at the end of it I want to redirect to another component:
我有一个简单的方法，最后我想重定向到另一个组件：
export class AddDisplay{
display: any;
addPairTo(name: string, pairTo: string){
this.display = {};
this.display.name = name;
this.display.pairTo = pairTo;
}
}
What I wanna do is at the end of the method redirect to another component:
我想做的是在方法结束时重定向到另一个组件：
export class AddDisplay{
display: any;
addPairTo(name: string, pairTo: string){
this.display = {};
this.display.name = name;
this.display.pairTo = pairTo;
this.redirectTo('foo');
}
}
How do I achieve this in Angular 2?

first configure routing
首先配置路由
import {RouteConfig, Router, ROUTER_DIRECTIVES} from 'angular2/router';
and
和
@RouteConfig([
{ path: '/addDisplay', component: AddDisplay, as: 'addDisplay' },
{ path: '/<secondComponent>', component: '<secondComponentName>', as: 'secondComponentAs' },
])
then in your component import and then inject Router
然后在您的组件导入中然后注入路由器
import {Router} from 'angular2/router'
export class AddDisplay {
constructor(private router: Router)
}
the last thing you have to do is to call
你要做的最后一件事就是打电话
this.router.navigateByUrl('<pathDefinedInRouteConfig>');
or
或者
this.router.navigate(['<aliasInRouteConfig>']);

@kit's answer is okay, but remember to add ROUTER_PROVIDERSto providers in the component. Then you can redirect to another page within ngOnInitmethod:
@kit 的回答没问题，但记得ROUTER_PROVIDERS在组件中添加到提供者。然后你可以重定向到ngOnInit方法中的另一个页面：
import {Component, OnInit} from 'angular2/core';
import {Router, ROUTER_PROVIDERS} from 'angular2/router'
@Component({
selector: 'loginForm',
templateUrl: 'login.html',
providers: [ROUTER_PROVIDERS]
})
export class LoginComponent implements OnInit {
constructor(private router: Router) { }
ngOnInit() {
this.router.navigate(['./SomewhereElse']);
}
}

This worked for me Angular cli 6.x:
这对我有用 Angular cli 6.x：
import {Router} from '@angular/router';
constructor(private artistService: ArtistService, private router: Router) { }
selectRow(id: number): void{
this.router.navigate([`./artist-detail/${id}`]);
}

callLog(){
this.http.get('http://localhost:3000/getstudent/'+this.login.email+'/'+this.login.password)
.subscribe(data => {
this.getstud=data as string[];
if(this.getstud.length!==0) {
console.log(data)
this.route.navigate(['home']);// used for routing after importing Router
}
});
}
