How get some data from json?

controllers.js

var vanapp = angular.module(‘starter.controllers’, [‘ngRoute’])

.config(function($routeProvider) {
$routeProvider
.when(’/’, {
templateUrl:‘login.html’
})
.when(’/app/dashboard’, {
resolve: {
“check”: function($location, $rootScope) {
if(!$rootScope.loggedIn){
$location.path(’/’);
}
}
},
templateUrl:‘dashboard.html’
})
.otherwise({
redirectTo: ‘/’
});
})

.controller(‘AppCtrl’, function($scope, $ionicModal, $timeout) {

// With the new view caching in Ionic, Controllers are only called
// when they are recreated or on app start, instead of every page change.
// To listen for when this page is active (for example, to refresh data),
// listen for the $ionicView.enter event:
//$scope.$on(’$ionicView.enter’, function(e) {
//});

})

.controller(‘LoginCtrl’, function($scope, $location, $rootScope, $ionicPopup) {
$scope.submit = function(){

    if($scope.username == 'admin' && $scope.password == 'admin'){

    }
