如何在ionic 2中使用navparams添加动态按钮

import { NavParams } from 'ionic-angular';

constructor(public navParams: NavParams) {
  // 其他代码...
}

<ion-content>
  <ion-list>
    <button ion-item *ngFor="let button of buttons" (click)="openPage(button.page, button.param)">
      {{ button.label }}
    </button>
  </ion-list>
</ion-content>

buttons = [
  { label: '按钮1', page: 'Page1', param: { id: 1 } },
  { label: '按钮2', page: 'Page2', param: { id: 2 } },
  // 其他按钮...
];

openPage(page, param) {
  this.navCtrl.push(page, param);
}
