Navigating & Passing Data Between Pages in Ionic 2

Published on October 20, 2016


    Navigating & Passing Data Between Pages in Ionic 2

    In Ionic you get a class named NavController to navigate between pages, and one named NavParams to get data from the page you navigated from.

    You start by importing NavController as well as the class of the page you’ll be navigating to in your starting component/page:

    Component: something.ts

    import { NavController } from 'ionic-angular';
    import { SomethingElsePage }
         from '../something-else/something-else';

    Then you inject NavController in your component’s class constructor:

    Component: something.ts

    constructor(public navCtrl: NavController) {}

    And now let’s say that your page template has a button like this:

    Template: something.html

    <button ion-button (click)="goToSomethingElse()">

    Then your component would have a goToSomethingElse() method like this:

    Component: something.ts

    goToSomethingElse() {

    In the SomethingElsePage component you’d use NavController’s pop to go back to the previous view:

    Component: something-else.ts

    goBack() {

    Passing and getting data with NavParams

    The above is all fine and good, but oftentimes we’ll want to pass data over to the page we’re navigating to. Just pass it as a JSON object to the second argument of the push call. In the below sample code, payload would be our JSON object that we’re passing:

    Component: something.ts

    goToSomethingElse(payload) {
        this.navCtrl.push(SomethingElsePage, payload);

    Now in your destination component/page, you’ll also need to import and inject NavParams:

    Component: something-else.ts

    import { NavController, NavParams } from 'ionic-angular';

    And now finally, you can access the data with NavParams’ get method. Let’s say for example that our payload JSON object as a ketchup key and you want its data:

    Component: something-else.ts

    ketchup: string = this.navParams.get('ketchup');
