I looked at: https://ionicframework.com/docs/api/config/Config/
This page used an example where the tabsPlacement on ion-tabs was changed for that one element.
I tried to recreate this with:
<ion-header>
<ion-navbar backButtonIcon="close">
<ion-title>settings-edit</ion-title>
</ion-navbar>
</ion-header>
<ion-content padding>
</ion-content>
There doesn't seem to be any changes with the navBar back button
There is no custom back button option in ionic simply change it as the button
<ion-header>
<ion-navbar hideBackButton="true">
<button ion-button menuToggle hideBackButton="true">
<ion-icon name="md-close" (click)="close()" ></ion-icon>
</button>
<ion-title>settings-edit</ion-title>
</ion-navbar>
</ion-header>
Try This Code and add below TS code in your page
close()
{
this.navctrl.pop();
}
As in the documentation, you should define it it in your app.module.ts
Add this to your #NgModule:
imports: [
BrowserModule,
IonicModule.forRoot(MyApp, {
backButtonIcon: 'close',
iconMode: 'ios',
modalEnter: 'modal-slide-in',
modalLeave: 'modal-slide-out',
tabsPlacement: 'bottom',
pageTransition: 'ios-transition'
})
]

I have used ion-tabs and side-menu for change route the app, both uses routerLink. And when i press Home tab in ion-tab to go back to home page inside other pages, route changed to home but home page constructor method and onInit methods does not invoke.
side-menu.component.ts
<ion-app>
<ion-split-pane contentId="main-content">
<ion-menu *ngIf="isAuthenticated$ | async" contentId="main-content" type="overlay">
<ion-content>
<ion-list id="inbox-list">
<div class="menu-header">
<ion-list-header>
<img src="assets/wa-logo.ico">
</ion-list-header>
<ion-note></ion-note>
</div>
<ion-menu-toggle auto-hide="false" *ngFor="let p of appPages; let i = index">
<ion-item (click)="selectedIndex = i" routerDirection="root" [routerLink]="[p.url]" lines="none" detail="false" [class.selected]="selectedIndex == i">
<ion-icon slot="start" [ios]="p.icon + '-outline'" [md]="p.icon + '-sharp'"></ion-icon>
<ion-label>{{ p.title }}</ion-label>
</ion-item>
</ion-menu-toggle>
</ion-list>
</ion-content>
<ion-footer>
<ion-menu-toggle auto-hide="false">
<ion-item
(click)="logout()"
routerDirection="root"
lines="none"
detail="true"
>
<ion-icon
slot="start"
ios='log-out-outline'
md="log-out-sharp"
></ion-icon>
<ion-label> Logout </ion-label>
</ion-item>
</ion-menu-toggle>
</ion-footer>
</ion-menu>
<ion-router-outlet id="main-content"></ion-router-outlet>
<ion-tabs *ngIf="isAuthenticated$ | async">
<ion-tab-bar [translucent]="true" slot="fixed">
<ion-tab-button (click)="onClick()">
<ion-icon name="home"></ion-icon>
<ion-label> Home </ion-label>
</ion-tab-button>
<ion-tab-button [routerLink]="['/features/new-request']">
<ion-icon name="document-text"></ion-icon>
<ion-label> New Request </ion-label>
</ion-tab-button>
<ion-tab-button [routerLink]="['/features/prev-requests']">
<ion-icon name="reader"></ion-icon>
<ion-label> All Requests </ion-label>
</ion-tab-button>
</ion-tab-bar>
</ion-tabs>
</ion-split-pane>
</ion-app>
So if i go inside prev-request page using ion-tab and once using hardware back button or ion-toolbar back button to changes route back to home page constructor and ngOnInit does not invoke, but if i route using side menu and go back with hardware back button or ion-toolbar back button constructor and ngOnInit methods are invoked.
prev-req.page
constructor(private _preReqService: PrevReqService,private platform: Platform,
private _modal: ModalService,
private _router: Router) {
this.platform.backButton.subscribeWithPriority(10, () => {
this._router.navigate(['/features/home'])
});
}
Still i don't have any clue why this happens.
Any idea why this happens ?
If you want to execute a function every time you go to a page Use Ionic Page Life Cycle.
ionViewWillEnter: Fired when the component routing to is about to animate into view.
ionViewDidEnter: Fired when the component routing to has finished animating.
ionViewWillLeave: Fired when the component routing from is about to animate.
ionViewDidLeave: Fired when the component routing to has finished animating.
export class ExamplePage implements OnInit {
constructor(){
}
ionViewWillEnter(){
console.log('Will Enter Fired') // will fire every time to go to a page.
}
}

I've been trying the ion-menu of Ionic 3. The "type=overlay" function works properly as the side menu overlays the screen, yet neither "push" nor "reveal" values for "type" attribute seem to be working.
When I click the button, nothing happens, but the button is sure clicked as I've checked. I have not tried them in an emulator/phone if they work. But the ionic-documents on it shows it can be tested on browser.
<ion-menu side="start" menuId="first" [content]="content" type="push">
<ion-header>
<ion-toolbar color="primary">
<ion-title>Start Menu</ion-title>
</ion-toolbar>
</ion-header>
<ion-content #content>
<ion-list>
<ion-item>Menu Item</ion-item>
<ion-item>Menu Item</ion-item>
</ion-list>
</ion-content>
</ion-menu>
<ion-header>
<ion-navbar>
<ion-title>Home</ion-title>
<ion-buttons end>
<button ion-button menuToggle (click)="openFirst()"><ion-icon name="add"></ion-icon></button>
</ion-buttons>
</ion-navbar>
</ion-header>
<ion-content>
content
</ion-content>
.
import { Component } from '#angular/core';
import { NavController, MenuController } from 'ionic-angular';
#Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
constructor(public navCtrl: NavController,
private menu: MenuController) {
}
openFirst() {
this.menu.enable(true, 'first');
this.menu.open('first');
}
}
I expect this code the push the entire page and reveal the side bar menu, but it does nothing.
Button click function is not required as menuToggle is used :
<ion-header>
<ion-navbar>
<ion-title>Home</ion-title>
<ion-buttons end>
<button ion-button menuToggle ><ion-icon name="add">
</ion-icon></button>
</ion-buttons>
</ion-navbar>
</ion-header>

I have implemented menu type.

I was using this tutorial https://alligator.io/ionic/ionic-4-tabs/ to create Routing for my Ionic Tabs, but unfortunately the displayed content is always hidden and can't be shown.
My home.page.html looks like this:
<ion-header>
<ion-tabs style="display: contents;">
<ion-tab-bar slot="top">
<ion-tab-button tab="popular">
<ion-label>SOme text</ion-label>
<ion-icon name="heart"></ion-icon>
<ion-badge>6</ion-badge>
</ion-tab-button>
</ion-tab-bar>
</ion-tabs>
</ion-header>
I defined the routings inside a home-routing.module.ts:
const routes: Routes = [
{
path: 'tabs',
component: HomePage,
children:
[
{
path: 'popular',
children:
[
{
path: '',
loadChildren: '../popular/popular.module#PopularPageModule'
}
]
}
]
}
]
And my popular.page.module.html looks like this:
<ion-header>
<ion-toolbar color="primary">
<ion-title>Home</ion-title>
</ion-toolbar>
</ion-header>
<ion-content padding>
<h1>Hallo</h1>
</ion-content>
I excpected so the h1-Tag "Hallo", but unfortunately it doesn't show anything. The interesting thing indeed, is that the h1-Tag is shown in Developer-Tools in the Browser.
Any ideas?
This has caused me a head headache XD. you shouldnt be putting your tabs in your header. the taps component/element is generated at the level above the page, where as the header element is generated within the page so sticking the tabs in the header is causeing all sorts of crazyness.
I went through the tutorial and got it to display correctly
home.page.html -
<ion-tabs>
<ion-tab-bar slot="top" color="primary">
<ion-tab-button tab="tab1">
<ion-icon name="home"></ion-icon>
<ion-label>Home</ion-label>
</ion-tab-button>
<ion-tab-button tab="tab2">
<ion-label>SOme text</ion-label>
<ion-icon name="heart"></ion-icon>
<ion-badge>6</ion-badge>
</ion-tab-button>
</ion-tab-bar>
</ion-tabs>
please comment for stuff you want me to add
I have 2 pages, login and home, when the user successfully logins, it will be directed to the home page and I set this as the root page. I've confirmed this by using navCtrl.canGoBackFunction and it is false. I tried adding a Menu Toggle but when I pressed the toggle button the menu does not show up
This is my home.html
<ion-header>
<ion-navbar color="primary">
<button menuToogle ion-button icon-only class="menu-button-left">
<ion-icon name="menu"></ion-icon>
</button>
<ion-title class="alogo"><img alt="logo" height="35" src="../../assets/imgs/logo.png" ></ion-title>
<button ion-button class="menu-button-right" (click)="logout()">
<p>Logout</p>
</button>
</ion-navbar>
</ion-header>
<ion-content padding-left padding-right>
</ion-content>
my home.ts
import { Component } from '#angular/core';
import { NavController } from 'ionic-angular';
import { LoginPage } from '../login/login';
import { AuthService } from '../../app/services/auth.service'
#Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
constructor(
public navCtrl: NavController,
private authService: AuthService
) {
}
ionViewDidLoad() {
console.log('ionViewDidLoad HomePage');
console.log(localStorage.getItem('token'));
}
logout(){
console.log('logout button clicked');
this.authService.logOut();
this.navCtrl.setRoot(LoginPage);
this.navCtrl.popToRoot();
}
}
my app.html
<ion-menu [content]="mycontent">
<ion-content>
<ion-list>
<p>List/p>
</ion-list>
</ion-content>
</ion-menu>
<ion-nav #mycontent [root]="rootPage" swipeBackEnabled="false"></ion-nav>
I've re-read multiple times the manual and I didn't see any issues with the way I did, the manual says it I put it in navbar the page should be root. I also tried using a toolbar but again clicking the menu toggle button does not do anything. Any idea ?
Persistent menus display the MenuToggle button in the Navbar on all pages in the navigation stack. To make a menu persistent set persistent to true on the element. Note that this will only affect the MenuToggle button in the Navbar attached to the Menu with persistent set to true, any other MenuToggle buttons will not be affected. In your code you have to change like below code.
my app.html
<ion-menu [content]="mycontent" persistent="true">
<ion-content>
<ion-list>
<p>List/p>
</ion-list>
</ion-content>
</ion-menu>
<ion-nav #mycontent [root]="rootPage" swipeBackEnabled="false"></ion-nav>
I am building a tabbed application in Ionic 2 which has five tabs one being the home page. The tabs work fine. I am trying to add a menu for each tab page other than the home page. I have duplicated and added the code below for each of the 4 pages in the home page just changing the menu id;s and the content id's. Everything works fine for the first page I access the subsequent pages I access just don't do anything. I thought this would be quite simple but already have spent days looking for a solution. The docs just refer to different menus on one page not different menus on several pages. Newbie so guess its simple. Help please.
<ion-header>
<ion-navbar color="dark">
<button ion-button menuToggle="menujoinus">
<ion-icon name="menu"></ion-icon>
</button>
<ion-title>JOIN US</ion-title>
</ion-navbar>
</ion-header>
<ion-menu [content]="joinuscontent" id="menujoinus">
<ion-content>
<ion-list>
<button ion-button block icon-right color="secondary" menuClose="menujoinus">Close
<ion-icon name="close"></ion-icon>
</button>
<button ion-item icon-left (click)="openPageFieldguides()">
<ion-icon name="compass"></ion-icon>
Field Guides
</button>
<button ion-item icon-left (click)="openPageVolunteers()">
<ion-icon name="clipboard"></ion-icon>
Volunteers
</button>
<button ion-item icon-left (click)="openPageOwner()">
<ion-icon name="key"></ion-icon>
Owners
</button>
</ion-list>
</ion-content>
</ion-menu>
<ion-nav #joinuscontent [root]="rootPage"></ion-nav>
It's a bit confusing but you need to add all the menus to the app component - not any of the sub pages - and then reference whichever you need from the sub page using the MenuController. In some cases you may need to disable/enable menus on the sub page but depends on the situation. Take a look at http://ionicframework.com/docs/api/components/app/MenuController/ and the "Multiple Menus on the Same Side" and "Multiple Menus on Different Sides" for more information.
An example:
<!-- Menu 1 -->
<ion-menu id="menu-one" [content]="nav">
<ion-header>
<ion-navbar>
<ion-title>Menu 1</ion-title>
</ion-navbar>
</ion-header>
<ion-content>
<ion-list>
<ion-item (click)="doSomething()" menuClose>
Item 1
</ion-item>
<ion-item (click)="doSomething()" menuClose>
Item 2
</ion-item>
</ion-list>
</ion-content>
</ion-menu>
<!-- Menu 2 -->
<ion-menu id="menu-two" [content]="nav">
<ion-header>
<ion-navbar>
<ion-title>Menu 2</ion-title>
</ion-navbar>
</ion-header>
<ion-content>
<ion-list>
<ion-item (click)="doSomething()" menuClose>
Item 1
</ion-item>
<ion-item (click)="doSomething()" menuClose>
Item 2
</ion-item>
</ion-list>
</ion-content>
</ion-menu>
<ion-nav #nav [root]="rootPage"></ion-nav>
And on the sub page:
import { Component } from '#angular/core';
import { MenuController } from 'ionic-angular';
#Component({
selector: 'sub-page',
templateUrl: 'sub-page.html'
})
export class SubPage {
constructor(public menuCtrl: MenuController) {
// menuCtrl.enable(false, 'menu-one');
menuCtrl.enable(true, 'menu-two');
}
toggleMenu() {
this.menuCtrl.toggle();
}
}
The gotcha is the doSomething() method needs to be on the app component, not the sub page component.
