如何处理 ionic3 中的页面刷新 (ctrl+R, F5)

Question

Let's say I have page1 and page2 in an angular application. From page1 I go to page2 by passing some parameters, ie.

given: navCtrl: NavController
this.nav.push(Page2, {id: 23});

and then in the constructor of page2:

given: navParams: NavParams
this.id = this.navParams.get('id');

If I refresh the page with ctrl+R or F5 then this.navParams.get('id') doens't have anything...it's null.

Is there anyway to cache parameters?

Thanks

You can cache your data using either the ionic native storage plugin https://ionicframework.com/docs/native/native-storage or sqlite https://ionicframework.com/docs/building/storage
