I have a problem when I try to use ion-nav-view. When I try to use it, it shows me black screen in the emulator but in ionic serve, it works perfectly for me.
I think it is a syntax error.
Also, when I create a blank project, it works perfectly in the emulator.

});
Try to make your templateUrl: 'templates/apps/index.html'. The forward slash makes the path absolute, which will work on ionic serve because its a web server running at the root of the domain. It doesn't work in app because files are loaded over the file:// protocol and are not at the root, so it might crash because you are referencing a file that doesn't exist and would be outside of the app and thus perhaps a permission issue.

I am new to AngularJs and very new to ui-router.
I seem to be having problems creating several routes. This is how I proceed, inspiring myself from a tutorial but failing to reproduce the result.
Here are my different files:

angular
.module('app', []);
3/about.js
angular
.module('about', ['ui.router']);
4/about.component.js
const about = {
template: '<div class="about">About</div>'
};
angular
.module('about', ['ui.router'])
.component('about', about)
.config(function ($stateProvider) {
$stateProvider.state({
name: 'about',
url: '/about',
component: 'about',
// template: "<div>About</div>"
})
});
There are 2 similar files for home and another 2 for contact.
There is obviously something wrong as we are only calling the app module and not the contact, home, about modules, but this is the way the tutorial was done.
It's not working (the different templates of each routed module are not showing) and I can't figure it out.
To ensure all the modules get bootstrapped accordingly, just simply set them all as the deps for app module:
angular
.module('app', ['home', ...])
One more thing is about setting the directive attribute ui-sref for <a ui-sref="home" /> to work best with ui-router module instead of #/home which works with ngRoute
Am absolutely new to Ionic and Firebase and was trying to create a Sample Project where I am trying to query from the Firebase Database using a check on a value. To make it clear since Firebase doesn't allow a WHERE clause in the SELECT query like conditions, so was trying to learn how to deal with that.
Here is a snapshot of my Firebase database.
My intention is simply to display on my View whichever data has the address value of 700030 in an array as we do in AngularJS using ng-repeat.
var app = angular.module('starter', ['ionic', 'firebase'])
app.run(function($ionicPlatform) {
$ionicPlatform.ready(function() {
if(window.cordova && window.cordova.plugins.Keyboard) {
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
cordova.plugins.Keyboard.disableScroll(true);
}
if(window.StatusBar) {
StatusBar.styleDefault();
}
});
})
app.controller('MainCtrl', function($scope, $firebaseArray){
var ref = new Firebase('https://helpee-70271.firebaseio.com');
$scope.result = $firebaseArray(ref);
ref.orderByChild("address").on("child_added", function(data) {
console.log("Initially :" + JSON.stringify($scope.result));
//console.log(data.val().address);
if(data.val().address == "700030"){
console.log(data.val().address);
$scope.result.push(data.val());
}
console.log(JSON.stringify($scope.result));
});
});

Here is my Code snippet. The problem am getting is that while the checking and retrieving of data is being done properly but at the View am seeing that the array containing all the elements irrespective of the Address check is getting printed first followed by the values that should be printed.
Here is the snapshot of the View and the console of the browser
Can anyone please help me how to correct this issue and explain me where am going wrong? Would be highly indebted as am really new to this and am willing to learn. Thanks in advance!!
Your problem is that you are filling your array twice.
First with all the data using this line:
$scope.result = $firebaseArray(ref);
And secondly you add the data you actually want in the child_added listener:
$scope.result.push(data.val());
So the simple solution is to change that first line to:
$scope.result = [];
Heres My code for my index page, I added ui-view and my app file is called "route-app.js" and have used bower angular ui-router.

UI router Js file
angular.module('router', ['ui.router'])
.config([function($urlRouterProvider, $StateProvider){
$urlRouterProvider.otherwise('/');
$StateProvider
.state('home', {
url: '/',
templateUrl: 'home.html'
})
}]);
Every time I click on the links not pops up. What have I done wrong here.
$StateProvider should be $stateProvider (the first letter is lowercase)
Refer to the documentation here for reference: https://github.com/angular-ui/ui-router.
Also open up your development console, there may be some console errors that might assist you in figuring out what the problem is
angular.module('router', ['ui.router'])
.config(['urlRouterProvider', '$stateProvider', function($urlRouterProvider, $StateProvider){
$urlRouterProvider.otherwise('/');
$StateProvider
.state('home', {
url: '/',
templateUrl: 'home.html'
});
}]);
The thing is that, you have used array notation for dependency injection but you actually did not inject anything.
Ok so you have a couple errors.
The first, and the most important, is that you define your custom scripts prior to including angular itself. So if you look at the console you will see a 'Reference Error: angular is not defined' error.
Second and third, as Alex and Vishal noted, the injection is wrong.
Here are the updated HTML (I removed all the unecessary comments from your code to make it clear where I changed anything. You can of course keep them in your page):
<!DOCTYPE html>
<html lang="en" ng-app="router">

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="js/bootstrap.min.js"></script>
</body>
</html>
and the script:
angular.module('router', ['ui.router'])
.config(['$urlRouterProvider', '$stateProvider', function($urlRouterProvider, $stateProvider){
$urlRouterProvider.otherwise('/');
$stateProvider
.state('home', {
url: '/',
templateUrl: 'home.html'
});
}]);
As an advice, make use of the browser console (by pressing F12). It will give you the errors occuring in your scripts.
Note: It is possible to include the custom scripts prior to the angular library, but it's pointless and needs extra code to make it work, so don't do it.
In the script file , change the value oftemplateUrl attribute from 'home.html' to './home.html'. You have to give root directory.Just giving the file name will not work.
angular.module('router', ['ui.router'])
.config([function($urlRouterProvider, $StateProvider){
$urlRouterProvider.otherwise('/');
$StateProvider
.state('home', {
url: '/',
templateUrl: './home.html'
})
}]);
First of all, you should use the ui-sref attribute and not a plain href attribute to make ui-router work properly. Second, your link should not contain a hashtag. In this case, it has to be "/", not "#/".
I'm using the latest ionic and I want to implement a firebase backend for my app. I followed the ionic get started guide, then used bower install to install firebase and angular fire.
The error produced is:
Uncaught Error: [$injector:modulerr] Failed to instantiate module starter due to:
Error: [$injector:modulerr] Failed to instantiate module starter.controllers due to:
Error: [$injector:modulerr] Failed to instantiate module firebase due to:
Error: [$injector:nomod] Module 'firebase' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.
So adding the firebase links to the index.html does not fix this issue at least for me. Using bower to install firebase it should bundle automatically just by passing in 'firebase' into the controller.js, however it produces this error. Any ideas? Thanks in advanced!
This is all that I've changed in the app thus far:

// TV Shows Table
var moviesRef = new Firebase("https://moviehunt.firebaseio.com/");
var sync = $firebase(moviesRef);
$scope.movies = sync.$asArray();
})
Okay, here was my solution, I started from scratch completely, instead created the ionic app with a side menu:
ionic start myApp sidemenu
then used bower and bower install firebase install angularfire
and then added the following html links to the index.html:
<script src="lib/firebase/firebase.js"></script>
<script src="lib/firebase-simple-login/firebase-simple-login.js"></script>
<script src="lib/angularfire/dist/angularfire.js"></script>
I'm working on an app that uses the ionic framework. This in-turn uses the ui-router. Currently, I have a pretty basic two-page app. However, it will expand to be much larger. At this time, I get an error when I transition from my first view to my second view. The error says:

I am using 1.0.0 beta 3 of the Ionic Framework. My app.js file looks like this:
"use strict";
var myApp = angular.module('myApp', ['ionic', 'ngRoute']);
myApp.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('intro', { url: '/', templateUrl: 'app/account/welcome.html', controller: 'WelcomeController' })
.state('login', { url: '/account/login', templateUrl: 'app/account/login.html', controller: 'LoginController '})
;
$urlRouterProvider.otherwise("/");
});
function WelcomeController($scope) {
}
function LoginController($scope) {
}

</ion-view>
The view transitions just fine. However, the error I showed above concerns me. I'm afraid its going to bite me in the ass later. Does anyone know what would be causing this? Does anyone know how I can fix this?
Thank you!
If your using the bundle ionic.js file, you don't need to include ui-router, it already is included. You also don't need to include ng-router too.
Heres the codepen
ngRoute refers to the normal default router angular uses.
While you put that as your dependency, you cannot use the UI-router method, i.e stateProviders and the states.
In your case you have to remove ngRoute from your dependencies, or [ ]
var myApp = angular.module('myApp', ['ionic', 'ngRoute']); to
var myApp = angular.module('myApp', ['ionic']);
and then troubleshoot further since its a null value, something else is broken.
