Angular 4+ : Manual redirect to route

问题:

I just recently started using angular 4 instead of angular.js 1.

I have followed the heroes tutorial to learn about the fundamentals of angular 4 and I am currently using angular's own "RouterModule" from the "@angular/router" package.

In order to implement some authorization for my application I would like to know how to manually redirect to another route, I can not seem to find any useful information about this on the internet.

Angular routing : Manual navigation

First you need to import the angular router :

import {Router} from "@angular/router"

Then inject it in your component constructor :

constructor(private router: Router) { }

And finally call the ..navigate method anywhere you need to "redirect" :

this.router.navigate(['/your-path'])

You can also set some parameters on your route, like user/5 :

this.router.navigate(['/user', 5])

Redirection in angularjs 4 Button for event in eg:app.home.html

<input type="button" value="clear" (click)="onSubmit()"/>

and in home.componant.ts

 import {Component} from '@angular/core';
 import {Router} from '@angular/router';

 @Component({
   selector: 'app-root',
   templateUrl: './app.home.html',
 })

 export class HomeComponant {
   title = 'Home';
   constructor(
     private router: Router,
    ) {}

  onSubmit() {
    this.router.navigate(['/doctor'])
 }
 }

回答3:

You should inject Router in your constructor like this;

constructor(private router: Router) { }

then you can do this anywhere you want;

this.router.navigate(['/product-list']);

Angular Redirection manually: Import @angular/router, Inject in constructor() then call this.router.navigate().

import {Router} from '@angular/router';
... 
...

constructor(private router: Router) {
  ...
}

onSubmit() {
  ...
  this.router.navigate(['/profile']); 
}

回答5:

Try this:

constructor(  public router: Router,) {
  this.route.params.subscribe(params => this._onRouteGetParams(params));
}
this.router.navigate(['otherRoute']);

回答7:

This should work

import { Router } from "@angular/router"

export class YourClass{

   constructor(private router: Router) { }

   YourFunction() {
      this.router.navigate(['/path']);
   }

}

You may have enough correct answers for your question but in case your IDE gives you the warning

Promise returned from navigate is ignored

you may either ignore that warning or use this.router.navigate(['/your-path']).then().
