使用iframe时，ionic应用程序不加载更新的html

// 在Ionic组件中
loadIframeContent() {
    const iframe = document.getElementById('myIframe') as HTMLIFrameElement;
    iframe.src = `your-url.html?t=${Date.now()}`; // 添加时间戳
}

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

@Component({
  selector: 'app-your-component',
  templateUrl: './your-component.component.html',
  styleUrls: ['./your-component.component.scss'],
})
export class YourComponent {
  constructor(private cdr: ChangeDetectorRef) {}

  refreshIframe() {
    this.cdr.detectChanges(); // 强制变更检测
  }
}

// 清除应用缓存的方法
clearAppCache() {
    localStorage.clear();
    sessionStorage.clear();
    window.location.reload();
}
