ionic2:如何将href标记从视图页面移动到Actionsheet (控制器)

<button ion-button (click)="openActionsheet()">打开Actionsheet</button>

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

@Component({
  selector: 'page-home',
  templateUrl: 'home.html'
})
export class HomePage {

  constructor(public actionSheetCtrl: ActionSheetController) {}

  openActionsheet() {
    let actionSheet = this.actionSheetCtrl.create({
      title: '选择操作',
      buttons: [
        {
          text: '操作1',
          icon: 'ios-alert-outline',
          handler: () => {
            console.log('操作1被点击');
          }
        },
        {
          text: '操作2',
          icon: 'ios-checkmark-circle-outline',
          handler: () => {
            console.log('操作2被点击');
          }
        },
        {
          text: '取消',
          role: 'cancel',
          icon: 'ios-close-circle-outline',
          handler: () => {
            console.log('取消按钮被点击');
          }
        }
      ]
    });

    actionSheet.present();
  }
}
