重新初始化组件或强制它在Angular中再次运行ngOnInit()

import { Component, OnInit, OnDestroy, ChangeDetectorRef } from '@angular/core';

@Component({
  selector: 'app-example',
  template: `
    <!-- Your component template here -->
  `
})
export class ExampleComponent implements OnInit, OnDestroy {
  // Your component variables and subscriptions here

  constructor(private cdr: ChangeDetectorRef) {}

  ngOnInit() {
    // Your initialization code here
  }

  ngOnDestroy() {
    // Your cleanup code here
  }

  reinitializeComponent() {
    // Reset variables and clear subscriptions
    // ...

    // Destroy and reinitialize the component
    this.ngOnDestroy();
    this.ngOnInit();

    // Force change detection to re-render the component
    this.cdr.detectChanges();
  }
}
