更改ngOnInit中的元素更改路由时无效，但可以访问元素

import { Component, OnInit } from '@angular/core';
import { ActivatedRoute, NavigationEnd, Router } from '@angular/router';

@Component({
  selector: 'app-your-component',
  templateUrl: './your-component.component.html',
  styleUrls: ['./your-component.component.css']
})
export class YourComponent implements OnInit {
  elementValue: string;

  constructor(private router: Router, private route: ActivatedRoute) { }

  ngOnInit(): void {
    this.router.events.subscribe(event => {
      if (event instanceof NavigationEnd) {
        // 在路由变化时执行元素更改操作
        this.elementValue = '新的值';
      }
    });
  }
}
