How to keep the active tab while navigating to another view? - angularjs

I'm working on a Cordova/Ionic 2/AngularJS project and I'm facing the following issue. I have defined 5 main navigation tabs with the corresponding views, but I have one view (this one contains an iFrame), which I want to navigate to from any of my main tabs, the problem is I need to keep the active tab selected
My tabs definition look like this:
<ion-tabs ng-controller="BaseTabs as ctrl"
class="tabs-icon-top tabs-color-active-positive"
delegate-handle="tabs">
<ion-tab title="Featured" icon="featured" ng-click="ctrl.openCatalog()"
ui-sref="tab.app-catalog.featured" on-select="ctrl.update()">
<ion-nav-view name="tab-app-home"></ion-nav-view>
</ion-tab>
<ion-tab title="Catalog" icon="shop" ng-click="ctrl.openCatalogSearch()"
ui-sref="tab.app-catalog-search" on-select="ctrl.update()">
<ion-nav-view name="tab-app-catalog-search"></ion-nav-view>
</ion-tab>
...
<ion-tab title="More" icon="more" ng-click="ctrl.openMore()"
ui-sref="tab.app-more-content" on-select="ctrl.update()">
<ion-nav-view name="tab-app-user"></ion-nav-view>
</ion-tab>
</ion-tabs>
in my iframe controller I have the following:
$stateProvider.state(
'tab.app-base-frame', {
url : '/base/frame:url',
parent : 'tab',
views : {
'tab-app-home' : {
templateUrl : 'templates/app/base/frame.html',
controller : 'BaseFrame',
controllerAs : 'ctrl'
}
},
params : {
url : ''
title : false
}
}
)
Since in the controller I have the views set tab-app-home, each time I open the iframe view I get the home tab selected instead of the one active before invoking the iframe.
So here is my question, is there a way to dynamically set the view based on parameters? Or maybe a more practical solution rather than the way I have done so far?
Thanks in advance for the help.

This is the solution that worked for me:
import {Tabs} from “ionic-angular”;
#Page({
template: <ion-tabs #paymentTabs [tabbarLayout]="tabBarLayout"
[selectedIndex]="tabsIndex" preloadTabs="false"> <ion-tab tabIcon="list-box"
tabTitle="Tab1" [root]="tab2"></ion-tab> <ion-tab tabIcon="list-box"
tabTitle="Tab2" [root]="tab2"></ion-tab> </ion-tabs>,
})
export class PaymentTab {
#ViewChild(“paymentTabs”) paymentTabs: Tabs;
constructor() {}
ngAfterViewInit() {
setTimeout(() => {
console.log(“this.paymentTabs”);
this.paymentTabs.select(1);
}, 500);
}
}

Ionic tab badge value not updating properly

This could be a misunderstanding of how Angular controllers work, but I am trying to understand why the badge values for my tabs are not being updated.
I have isolated the issue to a Codepen here: https://codepen.io/tyman7/pen/JKKEbO
Extract from HTML:
<ion-tab title="Home" icon="ion-home" href="#/tab/home" badge="badgeValue" ng-controller="HomeTabCtrl">
<ion-nav-view name="home-tab"></ion-nav-view>
</ion-tab>
Extract from JS:
.controller('HomeTabCtrl', function($scope)
{
$scope.badgeValue = 1;
$scope.updateTabValue = function()
{
$scope.badgeValue += 1;
}
}
I ended up finding a solution that involves creating another controller that the badge value looks at. I have modified the isolated Codepen slighty to demonstrate: https://codepen.io/tyman7/pen/pbbRpb
Extract from HTML:
<ion-tab title="Home" icon="ion-home" href="#/tab/home" badge="badgeValue" ng-controller="HomeCtrl">
<ion-nav-view name="home-tab"></ion-nav-view>
</ion-tab>
Extract from JS:
.controller('HomeTabCtrl', function($scope)
{
})
.controller('HomeCtrl', function($scope)
{
$scope.badgeValue = 1;
$scope.updateTabValue = function()
{
$scope.badgeValue += 1;
}
}
The thing is, I just don't understand why it needs to be done this way. What fundamental knowledge am I missing here?
You had multiple instances of the HomeTabCtrl. It created one when the 'tabs' state was entered and another when the 'tabs.home' state was entered. Your 'tab' badgeValue was in one instance and the 'tabs.home' value another. An Easy fix to the original is to change the name of the 'tabs.home' controller to 'HomeCtrl' instead and create an empty controller of that name. Then the updateTabValue will be called in the parent scope and update the badgeValue throughout.
Here is a codepen:

Ionic dynamic tabs are not working

I am new in Ionic and AnguarJs. I have created a tab dynamically using ng-repeat. Tab title values are coming correct but tab content are incorrect.
Here is my code,
<ion-tabs class="tabs-positive tabs-striped tabs-top theme-color">
<ion-tab ng-repeat="sub in subjects" title="{{sub.MockTestSubjectTitle}}">
<ion-tab-content name="ion-{{sub.MockTestSubjectTitle}}">
{{sub.MockTestSubjectTitle}}
</ion-tab-content>
</ion-tab>
Here tab titles are subject name eg: Physics, Chemistry and Maths. I need to view subject name in tab content when i click corresponding subjects.
It is working fine in static, Here is my static code
<ion-tabs class="tabs-positive tabs-striped tabs-top theme-color">
<ion-tab title="PHYSICS">
<ion-tab-content>
PHYSICS
</ion-tab-content>
</ion-tab>
<ion-tab title="CHEMISTRY">
<ion-tab-content>
CHEMISTRY
</ion-tab-content>
</ion-tab>
<ion-tab title="BIOLOGY">
<ion-tab-content>
BIOLOGY
</ion-tab-content>
</ion-tab>
Please help me to resolve the issue. Thanks in advance.
Here is the controller,
.controller('MocktestCtrl', function($scope,$ionicLoading,$stateParams,$http,$ionicTabsDelegate,$timeout){
$ionicLoading.show({
template: 'Loading...'
});
$scope.testName = $stateParams.testTitle;
$http({
method : "GET",
url : "http://ozternlmsio-api.azurewebsites.net/api/MockTest/GetMockTestData?mockTestId="+$stateParams.testId+"&userId="+USER_ID+"&mockTestGroupId="+$stateParams.testGroupId+"&courseId="+COURSE_ID+""
}).then(function mySucces(response) {
$ionicLoading.hide();
$scope.subjects = response.data.Subjects;
$timeout(function(){
$ionicTabsDelegate.select(0, true);
}, 1000);
}, function myError(response) {
$ionicLoading.hide();
});
})
This is not possible currently as there is already an open issue at Ionic repo for this. Check the link for more details: https://github.com/driftyco/ionic/issues/4454

how to dynamically enable a disabled ion-tab?

This should be pretty straight forward, but it def is not.
In my html i have 4 tabs, one of which is the default and the other 3 are manually disabled the ion-tab...my tabs are the standard ion template (static) tabs:
<ion-tab class="tabs-icon-top tabs-color-active-positive">
<ion-tab id="tab1" disabled="pageFlow.disableOtherTabs" ...>
<ion-nav-view name="tab1"></ion-nav-view>
</ion-tab>
<ion-tab id="tab2" disabled="pageFlow.disableOtherTabs" title="Tab2" icon-off='ion-off' icon-on='ion-on' href="#/tab/tab2">
<ion-tab id="tab3" disabled="true" ...>
<ion-tab id="tab4" disabled="true" ...>
</ion-tab>
This is working correctly...Tabs icons 2/3/4 visible but are greyed out and cannot be clicked. I then only have .controllers for tab1, tab2, tab3, tab4, but no controller for any kind of master "tabs" page.
In tab1 is a form, when the form is submitted, it is evaluated in the .controller and based on certain conditions is supposed to "enable" the 3 disabled tabs.
I have tried many many combinations to get them to enable so they won't be greyed out and can now be clicked - but NOTHING is working.
various things I have tried:
document.getElementById('tab2').disabled = false ;
angular.element(document.getElementById('#tab2').disabled = false ;
$ionicTabDelegate.select(1).disabled = false ; // this actually executes the tab1 controller/services but does not enable the icon - still can't click on it.
...and lord knows how many other combinations. But nothing is working. I have even defined "delegate-handle" and "ng-attr-id" to try and gain access to the ion-tab attributes - but again, nothing is working.
My tabs are define
Try creating a model like this in your controller which you will bind to in your HTML to dynamically change the rendering:
$scope.pageFlow = {
disableOtherTabs : true
}
Then when you submit your form change the value:
$scope.pageFlow.disableOtherTabs = false;
Finally, bind the model to your tabs:
<ion-tab id="tab2" disabled="pageFlow.disableOtherTabs" title="Tab2" icon-off='ion-off' icon-on='ion-on' href="#/tab/tab2">
Use the same property on all the tabs if you want them all to be enabled or add extra properties to control individual tabs.
UPDATED
In your app.js add a controller to your base tab:
.state('tab', {
url: "/tab",
abstract: true,
templateUrl: "templates/tabs.html",
controller: "tabsController"
})
Obviously inject it into your main html page and then this controller should be called before your navigate to "tab.tab1" which has your form. In this controller define your model from above. You will still need one more step however.
On your new controller add something like:
var refreshFinalizer = $rootScope.$on('updateTabsRefresh', function (event, data) {
$scope.pageFlow.disableOtherTabs = false;
});
$scope.$on('$destroy', function () {
refreshFinalizer ();
});
On your tab1 after the form is checked add the broadcast to the listener:
$rootScope.$broadcast('updateTabsRefresh');

How to load a html template into the $scope?

I'm trying to populate an ion-content container. I want to load HTML into the $scope depending on which tab the user clicks:
<ion-tabs tabs-type="tabs-icon-only">
<ion-tab ...>
<ion-tab title="Create" icon-on="ion-android-create">
<ion-content padding="true" class="has-header">
{{getCreate}}
</ion-content>
</ion-tab>
<ion-tab ...>
</ion-tabs>
This is the controller for this view:
(function () {
'use strict';
angular.module('ionicApp')
.controller('HomePageController', ['$scope', '$state', '$templateCache', HomePageController]);
function HomePageController($scope, $state, $templateCache) {
$scope.getCreate = function() {
// at the moment create.html is just simple static html.
return $templateCache.get('app/views/home/ads/create.html');
//return $templateCache.get('main.create'); // this also doesn't work
};
}
})
();
The two relevant states are defined as:
.state('main.home', {
url: '/home',
views: {
'main': {
templateUrl: 'app/views/home/home.html',
controller: 'HomePageController'
}
}
})
.state('main.create', {
url: '/create',
views: {
'main': {
templateUrl: 'app/views/home/ads/create.html',
controller: 'CreateAdController'
}
}
})
Am I going about this incorrectly? What do I need to do to load create.html into $scope.getCreate in my HomePageController?
your approach seems a bit too complicated to me.
first of all you would have to make sure that your template has been loaded to $templateCache. this only happens when the template is rendered for the first time somewhere in the app (for example by using the "templateUrl" property)
alternatively you could fetch the data from the file by an ajax call on your own and compile it with the given $interpolate, $compile functions from angular. but then again: this seems way too complicated for this case.
secondly you would have to use ng-bind-html instead, because the way you did it there would be sanitized html to be seen. so there would be stuff like
etc instead of a compiled html version of it.
probably you should simply use the ng-include directive instead and everything will be fine in a blink of an eye ;)
As raised by #Patrick Kelleter, your approach is overly complex including working manually with the $templateCache and compiling HTML.
Why not use the router the way it's designed?
First, rename the state's view so that you can reference it explicitly:
.state('main.create', {
url: '/create',
views: {
'create': {
templateUrl: 'app/views/home/ads/create.html',
controller: 'CreateAdController'
}
}
})
Then change state using ui-sref= on the tab, and insert the state's template using <ion-nav-view ...> with the specially named view.
<ion-tabs tabs-type="tabs-icon-only">
<ion-tab ...>
<ion-tab title="Create" icon-on="ion-android-create" ui-sref="main.create">
<ion-content padding="true" class="has-header">
<ion-nav-view name="create"></ion-nav-view>
</ion-content>
</ion-tab>
<ion-tab ...>
</ion-tabs>
The router will then insert the content of app/views/home/ads/create.html into the <ion-nav-view name="create"> element when the tab is clicked.
Here is a full walkthrough: Build an App with Navigation and Routing - Part 1
Simply use $http.get:
$http.get($scope.template.url).then (function(response) {
console.log(response);
$scope.contents = response.data;
});

Creating views outside ion-tabs on Ionic Framework

I'm new to Ionic but it's been a long time since I wanted to try it. I'm just playing around so maybe I'm not getting the full concept.
I'm trying to do a simple application with three tabs at the bottom and a settings icon that will be there for all three tabs. When you click into that icon, supposedly the tabs should hide and show the settings screen.
Since I don't want the user to loose any content, all the views inherit from a global one:
angular.module('app', ['ionic', 'debug']).config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('app', {
url: "/app",
abstract: true,
controller: 'AppController',
templateUrl: "ui/modules/tabs/view.html"
})
.state('app.compose-text', {
url: '/text',
views: {
'compose-text': {
templateUrl: 'ui/modules/text-composer/view.html'
}
}
})
.state('app.compose-draw', {
url: '/draw',
views: {
'compose-draw': {
templateUrl: 'ui/modules/draw-composer/view.html'
}
}
})
.state('app.compose-photo', {
url: '/photo',
views: {
'compose-photo': {
templateUrl: 'ui/modules/photo-composer/view.html'
}
}
})
.state('app.settings', {
url: '/settings',
views: {
'settings': {
controller: 'ui/modules/settings/ctrl.js',
templateUrl: 'ui/modules/settings/view.html'
}
}
});
// if none of the above states are matched, use this as the fallback
$urlRouterProvider.otherwise('/app/text');
});
angular.module('app').run(function($rootScope) {
});
Then, tabs/view looks like this:
<ion-nav-view name="settings"></ion-nav-view>
<ion-tabs class="tabs-assertive tabs-icon-only">
<ion-tab title="Text" icon="icon ion-ios7-compose-outline" href="#/app/text">
<ion-nav-view name="compose-text"></ion-nav-view>
</ion-tab>
<ion-tab title="Draw" icon="icon ion-edit" href="#/app/draw">
<ion-nav-view name="compose-draw"></ion-nav-view>
</ion-tab>
<ion-tab title="Photo" icon="icon ion-ios7-camera-outline" href="#/app/photo">
<ion-nav-view name="compose-photo"></ion-nav-view>
</ion-tab>
</ion-tabs>
And one of the views:
<ion-view title="Example" class="slide-left-right">
<ion-nav-buttons side="left">
<a class="button button-icon button-clear ion-ios7-gear-outline" href="#/app/settings"></a>
</ion-nav-buttons>
<ion-content padding="true">
<h1>Text</h1>
</ion-content>
</ion-view>
First thing I wonder is: Is there any way to reuse those buttons between all views? Seems useless to keep defining them over and over.
But that's not the real thing™. When I click on Settings, something get injected into the ion-nav-view however it contains a lot of stuff (which is not on the template) and also, it doesn't hide the other view nor the tabs.
Some screenshot:
(source: ionicframework.com)
What should be the right approach for this?
This is my first time answering a question here so please bear with me.
To navigate to a view without the tab bar:
Remove the "app" prefix from the settings state, so it is no longer a child to the parent abstract state (app).
.state('settings', {
url: '/settings',
views: {
'settings': {
controller: 'ui/modules/settings/ctrl.js',
templateUrl: 'ui/modules/settings/view.html'
}
}
});
**If you add any states after this one, be sure to delete semicolon, whereas semicolon denotes the end.
THAT IS A BAND-AID SOLUTION.
The full solution to your problem is to start with an ionic project template. Fortunately they have a tabs option, which is a global tab bar.
Command-line:
ionic start appName tabs
That should give you a proper starting template with everything you need. It also has sample controllers.js, services.js, and app.js files so you can just build from there. It will also help you structure your project correctly to prevent unexpected data from injecting into your tag.
Source 1: http://ionicframework.com/getting-started/
Source 2: http://ionicframework.com/docs/api/directive/ionNavView/
**Bonus: There is also a neat trick in source 2 that shows you how to keep all templates inside your index.html file to speed up the app and simplify your workflow.
Goodluck.
