Getting Angularjs ng-view to work - angularjs

I am trying to figure out how to build a SPA with angularjs. My routes are working and each partial page is loading in ng-view properly. I'm trying to load external json data. I had it working onnce but I can't figure out what I'm doing wrong. The goal is to list products and have a details page for each product. Any help would be greatly appreciated. Here's my code:
app.js
var myApp = angular.module('app', ['ngRoute']);
myApp.config(['$routeProvider','$locationProvider', function($routeProvider,$locationProvider) {
$routeProvider.
when('/home',{
templateUrl: 'partials/home.html',
controller: "storeCtrl"
}).
when('/about',{
templateUrl: 'partials/about.html',
controller: "storeCtrl"
}).
when('/computers',{
templateUrl: 'partials/computers.html',
controller: "storeCtrl"
}).
when('/smartphones',{
templateUrl: 'partials/smartphones.html',
controller: "storeCtrl"
}).
when('/tablets',{
templateUrl: 'partials/tablets.html',
controller: "storeCtrl"
}).
otherwise({
redirectTo: '/home'
});
}]);
myApp.controller('storeCtrl', ['$scope', '$http', function($scope, $http) {
$scope.homeHeading = 'Home';
$scope.aboutHeading = 'About Us';
$scope.computersHeading = 'Computers';
$scope.smartphonesHeading = 'Smartphones';
$scope.tabletsHeading = 'Tablets';
$http.get('products.json').success(function(data) {
$scope.products = data;
});
console.log($scope.products);
}]);
computers.html
<div ng-controller="storeCtrl">
<h1>{{computersHeading}}</h1>
<div ng-repeat="item in products">
<p>{{ item.name }}</p>
</div>
</div>

You should try this
$http.get('products.json').then(function(result) {
$scope.products = result.data;
});
And remove ng-controller from the view as you have already defined it in myApp.config()

Try to use $http.get service which returns a promise object.

broadcast and emit does not work with ng-router?

I want pass the value to one nerds controller to geek controller but unable to pass in ng-router.
<button type="Submit" ng-click="showUser()">Show Details</button>
.when('/geeks', {
templateUrl: 'views/geek.html',
controller: 'GeekController'
})
.when('/nerds', {
templateUrl: 'views/nerd.html',
controller: 'NerdController'
})
In Nerds controller I have this function
$scope.showUser=function(){
$rootScope.$broadcast('btnName',{message:"msg"})
}
In geek controller I receiving the value on page load itself but i am not getting the value pls help me to find the solution
$rootScope.$on('btnName',function(event,args){
$scope.msg=args.message;
console.log("$scope.message nnnn",$scope.msg)
})
The NerdController and the GeekController are in two separate pages, only one of the controllers can be active at a time, since angular has only one page open in the tab. So what I suggest is, pass the variable as a parameter to the route, you can see this in the example below.
JSFiddle Demo
JS:
var routingExample = angular.module('Example.Routing', []);
routingExample.controller('NerdController', function ($scope, $location) {
$scope.showUser = function(){
console.log("show");
$location.path('/geek/1');
}
});
routingExample.controller('GeekController', function ($scope, $routeParams) {
$scope.id = $routeParams.id;
});
routingExample.config(function ($routeProvider) {
$routeProvider.
when('/nerds', {
templateUrl: 'home.html',
controller: 'NerdController'
}).
when('/geek/:id', {
templateUrl: 'blog.html',
controller: 'GeekController'
}).
otherwise({
redirectTo: '/nerds'
});
});

one controller is loading views from other controllers, how and why?

I have the following div in my index.html, whose controller is MainCtrl. This is the div used to load views from different controllers.
<div ng-controller="MainCtrl">
<div ng-view></div>
</div>
And these are my controllers:
.config(['$routeProvider', function($routeProvider) {
$routeProvider.
when('/main', {
templateUrl: 'views/main.html',
controller: 'MainCtrl'
}).
when('/about', {
templateUrl: 'views/about.html',
controller: 'MainCtrl'
}).
when('/services', {
templateUrl: 'views/services.html',
controller: 'ServicesCtrl'
}).
when('/contact', {
templateUrl: 'views/contact.html',
controller: 'ContactCtrl'
}).
otherwise({redirectTo: '/main'})
}])
.controller('MainCtrl', ['$scope', '$http', function($scope, $http) {
$http.get('data/services.json').then(function(response){
$scope.services = response.data;
});
}])
.controller('ServicesCtrl', ['$scope', '$http', function($scope, $http) {
$http.get('data/services.json').then(function(response){
$scope.services = response.data;
});
}])
.controller('ContactCtrl', ['$scope', '$http', function($scope, $http) {
$http.get('data/locations.json').then(function(response){
$scope.locations = response.data;
});
}]);
It all works fine, but I do not understand how do all the views from different controllers get loaded automatically inside the <div ng-controller="MainCtrl"> ?
So for example if I go to mysite/services, it loads services.html, even though its controller is ServicesCtrl.
It seems logical to me that it should only load the view from MainCtrl, which is main.html and about.html, yet it loads them all irrespective of controller names, how come?
There shouldn't be an ng-controller="MainCtrl" because the controllers for each route are defined in your routing configuration.
If you have this in your page then when about or main load you will actually initialize 2 instances of MainCtrl. One instance will be invoked by the router and the other by ng-controller and this can be problematic.
That being said you could have an outer controller but it wouldn't be the same as the ones used in the routes

Redirect using AngularJS MVC4

Already done research and looked up doc. How can I use AngularJS to go from page1 to page2
Module (I'm not sure am I suppose to put in Index.cshtml)
var myApp = angular.module('app', ['ngRoute', 'Anj.FormController'])
.config(function ($routeProvider, $locationProvider) {
$routeProvider.
when("/home",
{ templateUrl: "/Index.cshtml" }).
when("/form",
{ templateUrl: "/Form" }).
otherwise({ redirectTo: "/Form.csthml" });
});
Index.cshtml
<div class="container" ng-app="app" ng-controller="FormCtrl"> Go to Form.</div>
Form.cshtml
<div class="container" ng-app="app" ng-controller="FormCtrl">Go to Home.</div>
I don't think put anything in the controller, if yes please tell me or show me the code. thanks.
Try to change your templateUrl to "/[ControllerName]/Index"
Where [ControllerName] is controller that you going to call
var myApp = angular.module('app', ['ngRoute', 'Anj.FormController'])
.config(function ($routeProvider, $locationProvider) {
$routeProvider.
when("/home",
{ templateUrl: "/Home/Index" }).
when("/form",
{ templateUrl: "/Form" }).
otherwise({ redirectTo: "/Home/Form" });
});

How to pass and read multiple params in URL - angularjs

There are 2 views with respective controllers.
The links are in View1.Clicking on this link should load View2 and also read the parameters.
This is what I have tried but the alert says - undefined.
View2 can load with/without params - each case having a different workflow.
View1.html:
<div ng-controller="view1ctrl">
<a href="#/view2/pqid/775/cid/4" >Link1</a>
</div>
app.js:
var app = angular.module('app', ['ngRoute']);
app.config(['$routeProvider', function ($routeProvider) {
$routeProvider
.when('/view1', {
templateUrl: 'App/views/view1.html',
controller: 'view1ctrl'
})
.when('/view2', {
templateUrl: 'App/views/view2.html',
controller: 'view2ctrl'
})
.when('/view2/:pqid/:cid', {
templateUrl: 'App/views/view2.html',
controller: 'view2ctrl'
})
.otherwise({
redirectTo: '/view1'
});
}]);
view2ctrl.js:
app.controller("view2ctrl", ['$scope','$routeParams',function ($scope, $routeParams) {
var init = function () {
alert($routeParams.pqid);
}
init();
}]);
You are nearly there:
.when('/view2/:pqid/:cid'
maps to a URL in this format :
view2/1234/4567
1234 being the pqid and 4567 the cid.
So your routing, I think is working, just change the link to #/view2/775/4.
Or if you want to keep the same link change your routing to:
#/view2/pqid/:pqid/cid/:cid

AngularJS ng-class active by any subroute

I have a tab I want to be activated by a link like this:
http://localhost:8020/client#/content
Therefore I have this list-element:
li ng-show="showContentItemsTab" ng-class="{active: isActive('/content')}">Content</li>
But I also want it to be active when sublinks are called:
http://localhost:8020/client#/content/531443caeb3f95600ef92e3f
Is there a way to apply all sublinks after /content ?
Something like:
li ng-show="showContentItemsTab" ng-class="{active: isActive('/content/*')}">Content</li>
Following the official angular js tutorial, you can set up routing as follows.
phonecatApp.config(['$routeProvider',
function($routeProvider) {
$routeProvider.
when('/phones', {
templateUrl: 'partials/phone-list.html',
controller: 'PhoneListCtrl'
}).
when('/phones/:phoneId', {
templateUrl: 'partials/phone-detail.html',
controller: 'PhoneDetailCtrl'
}).
otherwise({
redirectTo: '/phones'
});
}]);
The controller will be
var phonecatControllers = angular.module('phonecatControllers',[]);
phonecatControllers.controller('PhoneDetailCtrl', ['$scope', '$routeParams', '$http',
function($scope, $routeParams, $http) {
$http.get('phones/' + $routeParams.phoneId + '.json').success(function(data) {
$scope.phone = data;
});
}]);
So your can be fetched by using $routeParams
