Issue accessing page from side menu in Ionic 2 application

I am experiencing an issue where the page does not open when I click on it in the side menu.

Here is my app.component.ts file:

this.pages = [
                { title: 'NFC Page', component: NfcPage, note: 'NFC Page' },
                { title: 'Student Details', component: StudentDetails, note: 'Student Details' },
    ];

And this is my app.module.ts file:

@NgModule({
  declarations: [
    StudentDetails,
    NfcPage,
],
entryComponents: [
    StudentDetails,
    NfcPage,
  ],

Additionally, here is a snippet from my nfc.ts page:

 import {Component} from '@angular/core';
    import {IonicPage, NavController, NavParams} from 'ionic-angular';
    import {NFC, Ndef} from '@ionic-native/nfc';

    @IonicPage()
    @Component({
        selector: 'page-nfc',
        templateUrl: 'nfc.html',
    })
    export class NfcPage {

        constructor(public navCtrl: NavController,
                    public navParams: NavParams,
                    private nfc: NFC,
                    private ndef: Ndef) {
}
}

Finally, here is a section from my nfc.html page:

<ion-header>
    <ion-navbar>
        <button ion-button menuToggle>
            <ion-icon name="menu"></ion-icon>
        </button>
        <ion-title>NFCPage</ion-title>
    </ion-navbar>
</ion-header>

<ion-content padding>
    <p>NFC Page!</p>
</ion-content>

While the Student details page opens correctly, I am facing an issue where clicking on "Nfc page" does not result in any action.

Answer №1

To open a page through the side menu, you must set that page as the root page when clicking on the side menu option. Below is an example code snippet to achieve this:

app.html:

<ion-menu id="myMenu" [content]="mycontent">
    <ion-content>
        <ion-list>
            <ion-item ion-item small menuClose (click)="nav.setRoot(pages.nfc)">
                <ion-icon name="home" item-left menuClose></ion-icon> NFC 
            </ion-item> 
            <ion-item small menuClose (click)="nav.setRoot(pages.std_detils)">
                <ion-icon ios="ios-contact" md="ios-contact" item-left></ion-icon> Student Details
            </ion-item> 
        </ion-list>
    </ion-content>
</ion-menu>

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

app.component.ts:

this.rootPage = NfcPage;
this.pages = {
    "nfc": NfcPage,
    "std_detils": StudentDetails,
};

Answer №2

After some investigation, I successfully identified and resolved the issue at hand. It appears that the problem lies within the nfc.ts module's constructor. The private parameters private nfc: NFC and private ndef: Ndef were causing issues due to a malfunction in the plugin I was utilizing. By removing these two parameters from the constructor, I was finally able to access the desired page. Surprisingly, no exceptions were caught or displayed in the console during this process. Hopefully, this solution proves helpful to others facing similar challenges.
