Question

我为登录和注册做了一个切换按钮。我想按照此按钮切换状态导航到各个组件。

如何在条件内传递或路由自定义组件？

app.component.ts

import { Component } from '@angular/core';
import { RouterModule, Router, Routes } from '@angular/router';
import { LoginComponent } from './login/login.component';
import { RegisterComponent } from './register/register.component';
import { templateJitUrl } from '@angular/compiler';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'Demo';

  public show: boolean = false;
  public buttonName: any = 'Register';

  toggle() {
    this.show = !this.show;

    if(this.show) {
      this.buttonName = "Login";
      console.log(this.buttonName);
      // code to load login component

    }
    else {
      this.buttonName = "Register";
      console.log(this.buttonName)
      // code to load register component
    }

app.component.html

<html>
  <head>
      <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
  </head>
  <body>
<div style="text-align:center">
  <h1>
    Welcome to {{ title }}!
  </h1>
  <button (click)="toggle()" id="bt" routerLink="/register">{{buttonName}}</button>
     </div>
     <br />

<router-outlet></router-outlet>
</body>
</html>

您可以使用角度Router导航至路线。根据条件进行导航时，在模板中使用Router而不是routerLink很容易。

<html>
  <head>
      <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
  </head>
  <body>
<div style="text-align:center">
  <h1>
    Welcome to {{ title }}!
  </h1>
  <button (click)="toggle()" id="bt">{{buttonName}}</button>
     </div>
     <br />

<router-outlet></router-outlet>
</body>
</html>

在 component.ts 中，导入Router并将其注入到您的组件中。

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


constructor(private router: Router) {

}

toggle() {
    this.show = !this.show;

    if(this.show) {
      this.buttonName = "Login";
      this.router.navigate(['/login']);

    }
    else {
      this.buttonName = "Register";
      this.router.navigate(['/register']);
    }
}

根据按钮状态导航到自定义组件
