I have created a tabs project in ionic, And created deeplinks for About and Home pages which are also tabs.
I need to set the name but while setting the name the following result occur:
Issue1: url does not displays the name.
Issue2 : When I refresh the page with given url the tabs also disappears.
In tabs.html I have set <ion-tabs name="tabspage">
tabs.ts
import { Component } from '#angular/core';
import { ContactPage } from '../contact/contact';
#Component({
templateUrl: 'tabs.html'
})
export class TabsPage {
tab1Root = 'HomePage';
tab2Root = 'AboutPage';
tab3Root = ContactPage;
constructor() {
}
}
tabs.html
<ion-tabs name="tabshome">
<ion-tab [root]="tab1Root" tabUrlPath="tab1" tabTitle="Home" tabIcon="home"></ion-tab>
<ion-tab [root]="tab2Root" tabTitle="About" tabIcon="information-circle"></ion-tab>
<ion-tab [root]="tab3Root" tabTitle="Contact" tabIcon="contacts"></ion-tab>
</ion-tabs>
about.ts
import { Component } from '#angular/core';
import { NavController, IonicPage } from 'ionic-angular';
#IonicPage({
segment: 'about/:id'
})
#Component({
selector: 'page-about',
templateUrl: 'about.html'
})
export class AboutPage {
constructor(public navCtrl: NavController) {
}
}
home.ts
import { Component } from '#angular/core';
import { NavController, IonicPage } from 'ionic-angular';
#IonicPage({
segment: 'home'
})
#Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
constructor(public navCtrl: NavController) {
}
}
My git hub link is https://github.com/jainAdijain/myTabs.git
Need to change in tabs.ts And use tabs to deeplinks:
import { Component } from '#angular/core';
import { IonicPage } from 'ionic-angular';
import {ContactPage} from "../contact/contact";
#IonicPage({
name: 'page-tabs',
priority: 'high'})
#Component({
selector: 'page-tabs',
templateUrl: 'tabs.html',
})
export class TabsPage {
tab1Root='page-home';
tab2Root = 'page-about';
tab3Root = ContactPage;
constructor() {
}
}
Need to change app.component.ts
import { Component } from '#angular/core';
import { Platform } from 'ionic-angular';
import { StatusBar } from '#ionic-native/status-bar';
import { SplashScreen } from '#ionic-native/splash-screen';
#Component({
templateUrl: 'app.html'
})
export class MyApp {
rootPage:any ='page-tabs';
constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen) {
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();
splashScreen.hide();
});
}
}
tabs.html remain same.
Need to change in about.ts
import { Component } from '#angular/core';
import { IonicPage, NavController, NavParams } from 'ionic-angular';
#IonicPage({
segment: 'about/:id',
name: 'page-about'
})
#Component({
selector: 'page-about',
templateUrl: 'about.html',
})
export class AboutPage {
constructor(public navCtrl: NavController, public navParams: NavParams) {
}
ionViewDidLoad() {
console.log('ionViewDidLoad AboutPage');
}
}
Need to change home.ts
import { Component } from '#angular/core';
import { IonicPage, NavController, NavParams } from 'ionic-angular';
#IonicPage({
segment: 'home',
name: 'page-home'
})
#Component({
selector: 'page-home',
templateUrl: 'home.html',
})
export class HomePage {
constructor(public navCtrl: NavController, public navParams: NavParams) {
}
ionViewWillEnter() {
}
}
Also need to update app.module.ts
import { NgModule, ErrorHandler } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { IonicApp, IonicModule, IonicErrorHandler } from 'ionic-angular';
import { MyApp } from './app.component';
import { ContactPage } from '../pages/contact/contact';
import { StatusBar } from '#ionic-native/status-bar';
import { SplashScreen } from '#ionic-native/splash-screen';
#NgModule({

SplashScreen,

]
})
export class AppModule {}

I am new to ionic framework 4 with purpose to build android apps. I have generated home page by using command ionic generate page home I have tried to direct navigate the home.html instead of index.html in ionic. But have failed. Please help to fix this issue. What portions of code can help to navigate directly home.html
Code :
app.module.ts
import { BrowserModule } from '#angular/platform-browser';
import { NgModule, ErrorHandler } from '#angular/core';
import { IonicApp, IonicModule, IonicErrorHandler } from 'ionic-angular';
import { MyApp } from './app.component';
import { HelloIonicPage } from '../pages/hello-ionic/hello-ionic';
import { ItemDetailsPage } from '../pages/item-details/item-details';
import { ListPage } from '../pages/list/list';
import { StatusBar } from '#ionic-native/status-bar';
import { SplashScreen } from '#ionic-native/splash-screen';
#NgModule({
declarations: [
MyApp,
HelloIonicPage,
ItemDetailsPage,
ListPage
],
imports: [
BrowserModule,
IonicModule.forRoot(MyApp),
],
bootstrap: [IonicApp],
entryComponents: [
MyApp,
HelloIonicPage,
ItemDetailsPage,
ListPage
],
providers: [
StatusBar,
SplashScreen,
{provide: ErrorHandler, useClass: IonicErrorHandler}
]
})
export class AppModule {}
app.component.ts
import { Component, ViewChild } from '#angular/core';
import { Platform, MenuController, Nav } from 'ionic-angular';
import { HelloIonicPage } from '../pages/hello-ionic/hello-ionic';
import { ListPage } from '../pages/list/list';
import { StatusBar } from '#ionic-native/status-bar';
import { SplashScreen } from '#ionic-native/splash-screen';
#Component({
templateUrl: 'app.html'
})
export class MyApp {
#ViewChild(Nav) nav: Nav;
// make HelloIonicPage the root (or first) page
rootPage = HelloIonicPage;
pages: Array<{title: string, component: any}>;
constructor(
public platform: Platform,
public menu: MenuController,
public statusBar: StatusBar,
public splashScreen: SplashScreen
) {
this.initializeApp();
// set our app's pages
this.pages = [
{ title: 'Hello Ionic', component: HelloIonicPage },
{ title: 'My First List', component: ListPage }
];
}
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.
this.statusBar.styleDefault();
this.splashScreen.hide();
});
}
openPage(page) {
// close the menu when clicking a link from the menu
this.menu.close();
// navigate to the new page if it is not the current page
this.nav.setRoot(page.component);
}
}
In your app.component.ts:
Inject the router and then navigate to your desired page: (btw: Injections in the constructor should be private in 99%)
import { Router } from '#angular/router';
constructor(
public platform: Platform,
private router: Router,
) {}
initializeApp() {
this.platform.ready().then(() => {
this.router.navigate(['/home']);
});
}
I am assuming the path "/home" exists, because you said, that you generated the home-module with the ionic generator. If not, you have to add it in your app-routing-module.
I'm using ionic cli 4.6.0 with #ngx-translate/core 9.1.1, and #ngx-translate/http-loader 2.0.1. The pages are lazy loaded while the ngx-translate is used as shared module, i.e.
import { BrowserModule } from '#angular/platform-browser';
import { ErrorHandler, NgModule } from '#angular/core';
import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';
import { SplashScreen } from '#ionic-native/splash-screen';
import { StatusBar } from '#ionic-native/status-bar';
import { BrowserAnimationsModule } from '#angular/platform-browser/animations';
import { TranslateModule, TranslateLoader } from '#ngx-translate/core';
import { TranslateHttpLoader } from '#ngx-translate/http-loader';
import { HttpClientModule, HttpClient } from '#angular/common/http';
import { IonicStorageModule } from '#ionic/storage';
import { MyApp } from './app.component';
export function createTranslateLoader(http: HttpClient) {
return new TranslateHttpLoader(http, './assets/i18n/', '.json');
}
#NgModule({
declarations: [
MyApp
],
imports: [
BrowserModule, BrowserAnimationsModule,
IonicModule.forRoot(MyApp),
HttpClientModule,
IonicStorageModule.forRoot(),
TranslateModule.forRoot({
loader: {
provide: TranslateLoader,
useFactory: (createTranslateLoader),
deps: [HttpClient]
}
})
],
bootstrap: [IonicApp],
entryComponents: [
MyApp
],
providers: [
StatusBar,
SplashScreen,
{provide: ErrorHandler, useClass: IonicErrorHandler},
Logger
]
})
export class AppModule {}
. In app.component.ts whenever I set the default value to whichever language the app on restart it works as expected, i.e. translate.setDefaultLang('en') shows language in english while translate.setDefaultLang('fr') in french.
import { Component } from '#angular/core';
import { Platform } from 'ionic-angular';
import { StatusBar } from '#ionic-native/status-bar';
import { SplashScreen } from '#ionic-native/splash-screen';
import { TranslateService } from '#ngx-translate/core';
import { Storage } from '#ionic/storage';
import { Logger } from '../providers/logger';
#Component({
templateUrl: 'app.html'
})
export class MyApp {
rootPage:any = 'HomePage';
constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen,
translate:TranslateService,storage:Storage,logger:Logger) {
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();
splashScreen.hide();
// this language will be used as a fallback when a translation isn't found in the current language
translate.setDefaultLang('en');
});
}
}
I have created a page settings in which I have a select box which on change sets the language to the new input, i.e. settings.ts
import { Component } from '#angular/core';
import { IonicPage, NavController, NavParams } from 'ionic-angular';
import { TranslateService } from '#ngx-translate/core';
/**
* Generated class for the SettingsPage page.
*
* See https://ionicframework.com/docs/components/#navigation for more info on
* Ionic pages and navigation.
*/
#IonicPage()
#Component({
selector: 'page-settings',
templateUrl: 'settings.html',
})
export class SettingsPage {
languages:any[] = [
{value:"en",text:"English"},
{value:"fr",text:"French"}
];
selectedLanguage:string = "en";
constructor(public navCtrl: NavController, public navParams: NavParams,private translate: TranslateService) {
}
onChangeLanguage(selectedLanguage:string){
this.translate.use(selectedLanguage);
}
}
and in settings.html
<select [ngModel]="selectedLanguage" (ngModelChange)="onChangeLanguage($event)">
<option [value]="language.value" *ngFor="let language of languages">{{language.text}}</option>
</select>
What I would expect is when I use e.g. this.translate.use("fr") and I return to home page everything to be translated to french. It seems that it doesn't work like that.
How could I achieve something like that?
Just in case somebody needs it. I used the onLangChange which is an observable. The way I used it
import { NgModule, ElementRef, ViewChild } from '#angular/core';
import { trigger, state, style, animate,transition, query} from '#angular/animations';
import { Observable, Subscription } from 'rxjs/Rx';
import { Component } from '#angular/core';
import { NavController } from 'ionic-angular';
import { IonicPage } from 'ionic-angular';
import { TranslateService,LangChangeEvent} from '#ngx-translate/core';
#IonicPage()
#Component({
selector: 'page-home',
templateUrl: 'home.html',
})
export class HomePage {
private items:any=[];
constructor(public navCtrl: NavController,private translate: TranslateService) {
}
ionViewDidLoad(){
this.translate.onLangChange.subscribe((event: LangChangeEvent) => {
this.items=[this.translate.instant("Word1"),this.translate.instant("Word2")];
});
}
}
So whenever the language is changed whereever the "items" property is used, it's rendered with the new language.
I have this simple provider:
import { Injectable } from "#angular/core";
#Injectable()
export class DevicesService {
public check_string : any;
constructor(){
this.check_string = "Provider enabled";
}
getStatusString() { return this.check_string; }
}
and I am trying to pass that check_string variable to a ion-input in my home.ts:
<strong><ion-input round id="stringstatus" type="text" [(ngModel)]="stringstatus"></ion-input></strong>
import { Component } from '#angular/core';
import { NavController } from 'ionic-angular';
import { DevicesService } from '../../providers/devicefactory/devicefactory';
#Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
public stateString : string;
constructor(public navCtrl: NavController, private deviceProvider : DevicesService) {
this.stateString = this.deviceProvider.check_string;
//this.stateString = this.deviceProvider.getStatusString();
}
}
I tried both two ways, direct pass variable and getting return function but once I run app it shows blank page.. what I could have missed?
Thanks a lot to all
Cheers!
Try using deviceProvider.getStatusString(). Without using this in constructor;
constructor(public navCtrl: NavController, private deviceProvider : DevicesService) {
this.stateString = deviceProvider.getStatusString();
}
You can directly set it in your ngModel :
[(ngModel)]="deviceProvider.check_string"
or
[(ngModel)]="deviceProvider.getStatusString()"
Hello Rameez and saperlipopette,
I tried as both of you obtaining this:
devicefactory.ts
import { Injectable } from "#angular/core";
//import { BluetoothLE } from '#ionic-native/bluetooth-le';
#Injectable()
export class DevicesService {
public ble_status : boolean;
public check_string : any;
// public BLE : BluetoothLE
constructor(){
this.ble_status = false;
//this.BLE.initialize();
//this.BLE.isEnabled().then(result => { this.ble_status = result.isEnabled; });
this.check_string = "Provider enabled";
}
getStatus() { return this.ble_status; }
getStatusString() { return this.check_string; }
enableBLE() {
//if (this.ble_status) this.BLE.enable(); else this.BLE.disable();
if (this.ble_status) this.check_string = "Provider enabled"; else this.check_string = "Provider disabled";
}
}

This starter project comes with simple tabs-based layout for apps

Take a look at the <code>src/pages/</code> directory to add or change tabs,
update any existing page or create new pages.

#Component({

})
export class HomePage {
public ble_state : string;
constructor(public navCtrl: NavController, public deviceProvider : DevicesService) {
//this.ble_state = ( this.deviceService.ble_status ? "Bluetooth is enabled" : "BLuetooth is disabled" );
//this.ble_state = deviceProvider.check_string;
this.ble_state = deviceProvider.getStatusString();
}
}
Before I put also directly in [(ngModel)] but it goes for blank page..... I think it's related something about passing variables maybe because if I comment that:
this.ble_state = deviceProvider.getStatusString();
the app appears working...
Maybe it's related about ionic and cordova installation platforms or dependencies even if it didn't reported any errors during compilation?
Thanks
When I run ionic serve i'm getting the following error below. Why I'm I getting the error? Does it have to do with IonicModule.forRoot(MyApp)?

I created a simple tab layout application in ionic framework. I created a Extra tab and tried exactly as other tabs are implemented. But when i tried
Everything was a same as other tabs! What was i missing here?
My app.module.ts is:
import { NgModule, ErrorHandler } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { IonicApp, IonicModule, IonicErrorHandler } from 'ionic-angular';
import { MyApp } from './app.component';
import { AboutPage } from '../pages/about/about';
import { ContactPage } from '../pages/contact/contact';
import { HomePage } from '../pages/home/home';
import { TabsPage } from '../pages/tabs/tabs';
import { ListPage } from '../pages/lists/lists';
import { StatusBar } from '#ionic-native/status-bar';
import { SplashScreen } from '#ionic-native/splash-screen';
#NgModule({
declarations: [
MyApp,
AboutPage,
ContactPage,
HomePage,
ListPage,
TabsPage
],
imports: [
BrowserModule,
IonicModule.forRoot(MyApp)
],
bootstrap: [IonicApp],
entryComponents: [
MyApp,
AboutPage,
ContactPage,
HomePage,
ListPage,
TabsPage
],
providers: [
StatusBar,
SplashScreen,
{provide: ErrorHandler, useClass: IonicErrorHandler}
]
})
export class AppModule {}
Here ListPage is extra class i created! I am very new to this!
TabsPage is:
import { Component } from '#angular/core';
import { AboutPage } from '../about/about';
import { ContactPage } from '../contact/contact';
import { HomePage } from '../home/home';
import { ListPage } from '../lists/lists';
#Component({
templateUrl: 'tabs.html'
})
export class TabsPage {
tab1Root = HomePage;
tab2Root = AboutPage;
tab3Root = ContactPage;
tab4Root = ListPage;
constructor() {
}
}
And lists.ts file is:
import { Component } from '#angular/core';
import { NavController } from 'ionic-angular';
#Component({
selector: 'page-lists',
templateUrl: 'lists.html'
})
export class ListPage {
constructor(public navCtrl: NavController) {
}
}
Please check your tabs.html. It should be like:
<ion-tabs>
<ion-tab [root]="tab1Root"></ion-tab>
<ion-tab [root]="tab2Root"></ion-tab>
<ion-tab [root]="tab3Root"></ion-tab>
<ion-tab [root]="tab4Root"></ion-tab>
</ion-tabs>
