如何在ionic框架中拦截弹出窗口？

import { Component } from '@angular/core';
import { AlertController } from '@ionic/angular';

@Component({
  selector: 'app-home',
  templateUrl: 'home.page.html',
  styleUrls: ['home.page.scss'],
})
export class HomePage {

  constructor(private alertController: AlertController) {}

  ionViewDidEnter() {
    this.presentAlert();
  }

  async presentAlert() {
    const alert = await this.alertController.create({
      header: 'Alert',
      subHeader: 'Subtitle',
      message: 'This is an alert message.',
      buttons: ['OK']
    });

    // 拦截弹出窗口
    if (shouldInterceptAlert()) {
      return; // 取消弹出窗口的显示
    }

    await alert.present();
  }

  shouldInterceptAlert(): boolean {
    // 在这里编写你的拦截逻辑
    // 返回true表示拦截弹出窗口，返回false表示不拦截
    return true;
  }

}
