Guidance on accessing the sidemenu features in Ionic 3

I am a beginner with Ionic and I am attempting to access the side menu options by clicking on them. However, I am encountering an issue where I am unable to navigate to the desired page and receiving the error message: "Cannot read property 'component' of undefined". How can I successfully access these pages by clicking on the side menu options? Whenever I use push, all options lead to the same page rather than their specific destination.

import { Component, ViewChild } from '@angular/core';
import { IonicPage, NavController, NavParams, Nav} from 'ionic-angular';
import { DashboardPage } from '../dashboard/dashboard';
import { ProfilePage } from '../profile/profile';
import { sidemenuDeclaration } from '../../sideMenuDeclare';
import { MenuController } from 'ionic-angular';
import { FeaturesPage } from '../features/features';
import { MediaPage } from '../media/media';
import { BlogPage } from '../blog/blog';

@IonicPage()
@Component({
  selector: 'page-menu',
  templateUrl: 'menu.html',
})
export class MenuPage {
@ViewChild(Nav) nav:Nav;

  rootPage:any = DashboardPage;

  constructor(public navCtrl: NavController, public navParams: NavParams, public menuCtrl: MenuController) {
  }

options : sidemenuDeclaration[] = [
  {title : "Home" , icon : "home" ,component : DashboardPage},
  {title : "Features" ,icon : "settings" , component : FeaturesPage},
  {title : "Media" , icon : "images" , component : MediaPage},
  {title : "Blog" ,icon : "create" ,component : BlogPage},
  {title : "Contact" , icon : "contact" ,component : ProfilePage},
  {title : "Like Us" , icon : "logo-facebook" ,component : ProfilePage},
  {title : "Follow Us" , icon : "logo-twitter" ,component : ProfilePage}
]

  ionViewDidLoad() {
    console.log('ionViewDidLoad MenuPage');
  }
  goToProfile(){
    this.navCtrl.push(ProfilePage);
  }

  menuOptions(op){
    this.nav.setRoot(op.component);
  }

}
<ion-menu [content]='content'>
    <ion-header>

        <ion-toolbar color = "danger">
            <ion-title (click) = "goToProfile()">
                <ion-icon name="contact"></ion-icon>Profile
            </ion-title>
        </ion-toolbar>
    </ion-header>


    <ion-content padding>
        <button ion-item *ngFor = "let op of options" (click) = "menuOptions(op)">
            <ion-icon name = {{op.icon}}></ion-icon>
            {{op.title}}
        </button>
    </ion-content>

</ion-menu>

<ion-nav #content [root]="rootPage"></ion-nav>

Answer №1

When using the menuOptions function, remember to include the necessary argument in your (html) template. Here is an example snippet that can be used.

<ion-content padding>
    <button ion-item *ngFor="let opt of options" (click)="menuOptions(opt)">
        <ion-icon name={{opt.icon}}></ion-icon>
        {{opt.title}}
    </button>
</ion-content>
