Question

我有一个重定向到另一个页面的函数，我希望重定向后的页面也重新加载。

我要在重定向到登录页面后重新加载它。使用“ window.location.reload（）”会重新加载当前页面，该页面是主页，而不是登录页面。如何重新加载特定页面？

homeComponent.ts

import { Component, OnInit } from '@angular/core';
import { Router } from '@angular/router';
import { FormGroup, FormBuilder, FormControl, Validators, Form } from '@angular/forms';
import { LoginComponent } from '../authentification/login/login.component';



@Component({
  selector: 'app-home',
  templateUrl: './home.component.html',
  styleUrls: ['./home.component.scss']
})



export class HomeComponent implements OnInit {
  
  ngOnInit(): void {
   
  }

  constructor(private router: Router) { }


   redirection(){
    this.router.navigate(['/login']);
   }

  
}

Answer 1

你为什么不使用

redirection(){
   window.location.href="yourpagedomain/login"
 }

它将加载页面。

Answer 2

在登录页面上，您可以捕获导航事件，然后，如果为true，则可以重新加载表单。希望对您有所帮助：

在您的登录页面上：

编辑：此代码有效：

export class LoginPage implements OnInit {
  
  constructor(private router: Router) {
   router.events.subscribe(val => {
      if (val) {
        this.refreshForm(); // Refresh your form
      }
    });
  }
 
  ngOnInit(): void {

  }

}
