My page stuck when i press logout button

Ionic Framework ionic-v3
1

i have problem only with this page,

import { Component, ViewChild } from ‘@angular/core’;
import { Nav, Platform } from ‘ionic-angular’;
import { StatusBar } from ‘ionic-native’;
import { Storage } from ‘@ionic/storage’;

import { Page2 } from ‘…/pages/page2/page2’;
import {Admin} from “…/pages/admin/admin”;
import {Page1} from “…/pages/page1/page1”;

@Component({
templateUrl: ‘app.html’,
})
export class MyApp {
@ViewChild(Nav) nav: Nav;

rootPage: any = Page1;
token:any;
pages: Array<{title: string, component: any}>;
public local : Storage;

constructor(public platform: Platform,public storage:Storage) {
this.initializeApp();
this.local = new Storage();
this.local.get(‘token’).then((value)=>{
this.token=value;
});
// used for an example of ngFor and navigation
this.pages = [
{ title: ‘Page one’, component: Page1 },
{ title: ‘Page Two’, component: Page2 },
{ title: ‘Admin’, component: Admin }
];

}

initializeApp() {
this.platform.ready().then(() => {
// Okay, so the platform is ready and our plugins are available.
// Here you can do any higher level native things you might need.
StatusBar.styleDefault();
});
}

openPage(page) {
// Reset the content nav to have just this page
// we wouldn’t want the back button to show in this scenario
this.nav.setRoot(page.component);
}
Logout(){
console.log(“logout check”);
this.local.remove(‘username’);
this.local.remove(‘token’);
this.nav.setRoot(Page1);
this.token=“”;

}
}

when i write these lines

this.local = new Storage();
this.local.get(‘token’).then((value)=>{
this.token=value;
});
or when i press on logout function, my page stuck and i have to restart chrome browser again. i don’t know what the reason for it. what i’m trying to do is to get the token variable from storage and when i press logout to remove it. i’m not sure if it is the best way…

Is your storage added in providers in app.module.ts?

try using this if you are not using to set your root inside logout method.

this.navCtrl.setRoot(HomePage);

in your template html,

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

And moreover when I tried to do the same flow before somehow it was not falling into place, not because of ionic, but the sequence of screen flows. So my suggestion is to keep your features in pages and move login/logout/signup as modals or popups, so whenever your user is signed in you can show the page if not show the login modal, you can do this check before you load contents of each page.

I think you should stop linking your new post and issues.

It is a feature to discuss related issues or support.
