如何捕捉用户在浏览器中单击back按钮并在Angular中显示模式

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

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

  constructor(private router: Router) { }

  ngOnInit(): void {
    this.router.events.subscribe(event => {
      if (event instanceof PopStateEvent) {
        // 在这里处理用户点击返回按钮的逻辑
        // 可以根据需要显示相应的模式
      }
    });
  }

}
