When i make hide-nav-bar="true" it also makes my sidebar menu disappear in the other pages i didnt wanted to. I just want to make the nav and side menu go away in the home page, but in the other pages my side menu is replaced for a back arrow for some reason. how can i solve this?
This is how it looks
This is how it is supposed to be
My code
<ion-view hide-nav-bar="true" title="Home" id="page1">
<ion-content padding="true" class="has-header backg">
<img class="log" src='../../img/image2.png' alt="HTML5 Icon" style="width:90px;height:90px;">
</ion-content>
</ion-view>
Please take a look at this plunker.
I just want to make the nav and side menu go away in the home page
In order to do that, you can, first, avoid including a header in your view. By just including and ion-content element in your home page html code, that view is not gonna have a navbar.
<ion-content>
<p>Home page</p>
<!-- ... -->
<!-- ... -->
</ion-content>
Even though we're not showing the navbar, the user could open the side menu by slicing it from the left (in this case) so we need to make sure to avoid that from happening like this:
Add an id to the ion-menu element like this:
<ion-menu [content]="content" side="left" id="menu">
<ion-toolbar secondary>
<ion-title>Menu</ion-title>
</ion-toolbar>
<ion-content>
<ion-list>
<button ion-item menuClose="menu" detail-none>
Close Menu
</button>
</ion-list>
</ion-content>
</ion-menu>
And then in your HomePage.ts disable it like this:
import { MenuController, ... } from 'ionic-angular';
#Component({
templateUrl:"home.html"
})
export class HomePage {
constructor(private menuCtrl: MenuController, ...) { }
ionViewDidEnter() {
this.menuCtrl.enable(false, 'menu');
}
// ...
}
in the other pages my side menu is replaced for a back arrow for some
reason.
That's related to the navigation array and how Ionic2 handles it. If you push a new page, that back arrow will be shown. Even though you can hide it, if the app is being run in an android device with a physical back button, the user will still be able togo back to the home page. If you don't want to let the user go back to the HomePage (because is the login page or something like that) use the setRoot method instead.
this.nav.setRoot(NewPage);

The ion-back-button does NOT show up to the right of the ion-menu-button. Why is that?
the ion-menu-button and the ion-title show properly and aligned on the same horizantal position.
<ion-header>
<ion-toolbar>
<ion-buttons slot="start">
<!-- navigation button-->
<ion-menu-button></ion-menu-button>
<!-- optional back button-->
<ion-back-button></ion-back-button>
</ion-buttons>
<ion-title>
{{ pageTitle | translate}}
</ion-title>
</ion-toolbar>
</ion-header>
In the DOM inspector the CSS display attribute of the ion-back-button is set to none. Why would it set itself to none?
I used
this.navCtrl.navigateForward('/term/' + term);
to navigate to this page, thus I expect the back button to pick this up. Why is navigateForward not adding to the stack, which would make the ion-back-button show?
If there is no page in Stack then
<ion-back-button></ion-back-button>
will not show. If you want to show then You need to be added a specific page in "defaultHref" Attribute.
<ion-back-button defaultHref="logout"></ion-back-button>
you need to be learned from here
https://ionicframework.com/docs/api/back-button
It will not visible if there will be no previous overlay/page to show
So you can set css
ion-back-button {
display: block;
}
Then add click event on element
<ion-back-button (click)="close()">
<ion-icon name="close"></ion-icon>
</ion-back-button>
Add on .ts file
click() {
this.modalCtrl.dismiss();
}
For anyone who has this trouble, and the ion-back-button is still not appearing, check that you have the IonicModule imported in your page's module. It happened to me that I created a component for the ion-header and the ion-back-button was not appearing. It was because my ComponentsModule (the one that declares and exports all my components) had only the CommonsModule imported and not the IonicModule. So always check for the IonicModule in your imports. Otherwise the back button will not appear
Is it root page? if so ion-back-button will not show up.
Try adding the attribute defaultHref. For example: <ion-back-button defaultHref="home"></ion-back-button>. it should show up regardless of having no navigation stack.
So Ionic developers make life complicated, now (Ionic5) the attribute is called default-href and not defaultHref.
But still when clicking not loading to the href.
Workaround. I programmatically decide with the URI path. Drawback, if more detail pages are added to the app, they need to be added (e.g. in an array of back-button-qualifying paths).
<ion-button *ngIf="router.url.includes('/term/')"><ion-icon name="arrow-back"></ion-icon></ion-button>
Added the Router Object to the constructor of this component
constructor(public router: Router) { }
If someone still comes up with why the programmatic navigation does NOT add to the navigation stack - so that the back button would appear on the detail page - I gladly listen.
Just need to add the color in scss file to show up.
ion-back-button{
--color: black;
}
And also don't forget to indicate the href, adding it html file
<ion-buttons slot="start">
<ion-back-button defaultHref="YourRouteHere"></ion-back-button>
</ion-buttons>
Make sure you arrived to that page via a router link that modifies the route history. Otherwise the backbutton wont show because there is no recorded history of a previous route.
My issue was, the link i clicked which takes me to a page forward, had routerDirection="none". So there was no previous route so my back button didn't show.
Changing
<IonRouterLink routerDirection="none" routerLink={`/item/${item.id}`}>...</IonRouterLink>
To
<IonRouterLink routerDirection="forward" routerLink={`/item/${item.id}`}>...
fixed my issue.
I try to make a little app in ionic2 to learn about it but I have a problem with navigation.
In fact I have well understand the difference between a rootpage (change whit nav.setRoot) and a "normal" page (add with nav.push). The thing is for my app I'll need to be able to open a side menu (this is ok if I'm on a rootpage but not it's not ok with the second type of page) and to be able to go back (this is ok with a push page but not with a rootpage).
So for me this type of page should be push and not a root page but how repear side menu on this type of page?
Thank you.
EDIT:
What about using persistent="true" in your ion-menu item? Like you can see in Ionic2 docs:
Persistent Menus 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.
So your app.html woul be:
<ion-menu [content]="content" persistent="true">
<ion-toolbar>
<ion-title>Pages</ion-title>
</ion-toolbar>
<ion-content>
<ion-list>
<button menuClose ion-item *ngFor="let p of pages" (click)="openPage(p)">
{{p.title}}
</button>
<button menuClose ion-item (click)="logout()">Logout</button>
</ion-list>
</ion-content>
</ion-menu>
<ion-nav [root]="rootPage" #content swipeBackEnabled="false"></ion-nav>

I'm developing an ionic app on android. I'm facing a problem where back button doesn't show up when there's no page to go back.
For more detailed explanation:
Scenario 1: Button from side menu when click go to View B.
Scenario 2: Button from side menu to View A, then button from View A to View B.
Scenario 2 View B shows back button, since it has a previous page, but Scenario 1 doesn't have a previous page that's why it doesn't show the back button, How do I display the menu button if there's no back button?
Here's my code below:
<ion-view view-title="MY View">
<ion-nav-bar>
<ion-nav-back-button></ion-nav-back-button>
<ion-nav-buttons side="right">
<button class="button" type="submit"
ng-click="goEdit(data.ID)">Edit</button>
</ion-nav-buttons>
</ion-nav-bar>
<ion-content class="has-header">
</ion-content>
</ion-view>
Additional Info:
When removing the <ion-nav-bar> it displays the menu button, but of course will no longer show back button and edit button. When I try putting ng-hide in <ion-nav-bar ng-hide="isMenu"> it doesn't show any nav-bar since it's hidden but from html inspect element it's still there but hidden only. Any work around on this?
If you set a page as a rootPage and also use menu in you will see menu button. when navigating to another page from root if you use navCtrl.push() back button will automatically be added to the pushed view.if you set second page as a rootPage again you will see menu button again.
But if you want to implement it yourself that is another thing.

Consider customizing the navbar/toolbar only for the pages that needs it.
By having an ion-toolbar in the ion-header, it appears on top of the default ion-navbar. So it is a workaround to have a custom header bar with my close icon and my custom function gotoHome(). That's the best way i found to customize the 'navbar' for a particular page.
<ion-header>
<ion-toolbar>
<ion-buttons left>
<button ion-button icon-only (click)="gotoHome()">
<ion-icon name="close"></ion-icon>
</button>
</ion-buttons>
<ion-title>Title</ion-title>
</ion-toolbar>
</ion-header>
<ion-content padding>
...
</ion-content>
The same answer applies to this topic, for reference :
Ionic Change back button icon for one page only
When navigating from one page to another, Ionic automatically display back button at the navigation bar. However, there are certain case where ionic don't display the back button. For example, when you navigate from a tab page to a none tab page.
How can I force Ionic to display back button on certain page?
Javascript:
.state('app.tab.playlists', { //<!-- Tab content page
url: '/playlists',
views: {
'tab-Content': {
templateUrl: 'templates/playlists.html',
controller: 'PlaylistsCtrl'
}
}
})
.state('app.singer', { //<!-- Not tab content page (if you navigate from tab page to this page, back button will not displayed)
url: '/singer',
views: {
'menuContent': {
templateUrl: 'templates/singer.html'
}
}
})
You can tell it in your controller. Try:
.controller('yourCtrl', function($scope) {
$scope.$on('$ionicView.beforeEnter', function (event, viewData) {
viewData.enableBack = true;
});
})
But like LeftyX said. The history function for tab to non tab view is buggy.
Ionic manages a history while you're navigating from one view to the other.
$ionicHistory keeps track of views as the user navigates through an
app. Similar to the way a browser behaves, an Ionic app is able to
keep track of the previous view, the current view, and the forward
view (if there is one). However, a typical web browser only keeps
track of one history stack in a linear fashion.
Unlike a traditional browser environment, apps and webapps have
parallel independent histories, such as with tabs. Should a user
navigate few pages deep on one tab, and then switch to a new tab and
back, the back button relates not to the previous tab, but to the
previous pages visited within that tab.
There's a bug open on github which hasn't been fixed yet (and will only be fixed in 2.0) where Adam Bradley states:
The back button does not display because when you go into a tab, it
enter's it own "history", meaning each tab has its own navigation back
and forward.
So, basically, when you move from tabs to regular view you're going to lose the back button.
What you can do is to create one yourself:
<ion-nav-buttons side="left">
<button class="button back-button buttons button-clear header-item" ng-click="goBack()">
<i class="icon ion-ios-arrow-back"> Back</i>
</button>
</ion-nav-buttons>
and place it inside your view:
<ion-view view-title="home">
<ion-nav-buttons side="left">
<button class="button back-button buttons button-clear header-item" ng-click="goBack()">
<i class="icon ion-ios-arrow-back"> Back</i>
</button>
</ion-nav-buttons>
<ion-content padding='true' scroll='false' has-footer='false'>
<div class="card">
<div class="item item-text-wrap">
HOME PAGE
</div>
</div>
</ion-content>
</ion-view>
As you can see I've used ng-click="goBack()" for the button.
In your controller you simply would:
$scope.goBack = function(){
$ionicHistory.goBack();
}
don't forget to inject $ionicHistory in your controller.
PS: This is a over-simplified solution as it does not check if the history has got a backview:
$ionicHistory.viewHistory().backView
Add follwing lines inside your
<ion-navbar hideBackButton="true">
<button (click)="back()" class="back-button disable-hover bar-button bar-button-ios back-button-ios bar-button-default bar-button-default-ios show-back-button" ion-button="bar-button" ng-reflect-klass="back-button" ng-reflect-ng-class="back-button-ios" style=""><span class="button-inner"><ion-icon class="back-button-icon icon icon-ios back-button-icon-ios ion-ios-arrow-back" role="img" ng-reflect-klass="back-button-icon" ng-reflect-ng-class="back-button-icon-ios" aria-label="arrow back" ng-reflect-name="ios-arrow-back"></ion-icon><span class="back-button-text back-button-text-ios" ng-reflect-klass="back-button-text" ng-reflect-ng-class="back-button-text-ios">Back</span></span><div class="button-effect"></div></button>
