Showing 'details' of specific object- pass JSON value from one page to another to query API

Question

I want to pass a value from one element, to another html page.

Very simply- I want to click an object (within an ng-repeat), and be directly to a page with more detail about that object only.

1. Take a value (product_id) from the $http getUrl (a value not a directive in my html- can javascript still find it?). Pass this value so it can be accessed if "more info" is requested.

2. Using a value from take the current product_id, and use that number to fill a getURL to pull a json object for the following "detail" page.

3. Using ui-sref it opens a new page (not a new URL address, just a different HTML document)

4. In this new page it should have the product details

This is my my attempt:

.factory('cardsApi', ['$http', function ($http) {
    var apiUrl = 'http://stashdapp-t51va1o0.cloudapp.net/api/item/';

    function productId(min, max) {
        return Math.floor(Math.random() * (max - min + 1) + min);
    }

    var getApiData = function () {
        return $http.get(apiUrl + productId(1, 50000))
    };

    var postRecordLikes = function (product_id) {
        return $http.post('http://test.com/analytic/' + product_id);
    }

    return {
        getApiData: getApiData,
        postRecordLikes: postRecordLikes
    };
}])

.controller('CardsCtrl', ['$scope', 'TDCardDelegate', 'cardsApi', '$http',
    function ($scope, TDCardDelegate, cardsApi, $http) {
        console.log('CARDS CTRL');
        $scope.cards = [];

        $scope.onSwipeRight = function (product_id) {
            console.log(product_id)
        }


        $scope.onSwipeLeft = function (product_id) {
            console.log(product_id)
        }


        // <======  Rewrite with accounts preferences
        for (var i = 0; i < 7; i++) {
            cardsApi.getApiData()
                .then(function (result) {
                    //console.log(result.data) //Shows log of API incoming
                    $scope.cards.unshift(result.data);
                    $scope.product_id = result.data.product_id;
                })
                .catch(function (err) {
                    $log.error(err);
                });
        }
        // Rewrite with accounts preferences =====>

        $scope.$watchCollection('cards', function (newVal, oldVal) {
            if (newVal < oldVal) {
                cardsApi.getApiData()
                    .then(function (result) {

                        // console.log(JSON.stringify(result.data)); Shows log of API results

                        $scope.cards.unshift(result.data);

                        // console.log($scope.cards);

                    })
                //.catch(function (err) {
                //    console.log(err);
                //});
            }
        });

        $scope.cardSwiped = function (card) {
            console.log(card);
            postRecordLikes(card);
        };

        //$scope.cards = Array.prototype.slice.call(cardTypes, 0);

        //Removes card from top of stack
        $scope.cardDestroyed = function (index) {
            $scope.cards.splice(index, 1);
        };

        $scope.addCard = function () {
            var newCard = $scope.cards[$scope.cards.length];
            //newCard.id = Math.random();
            $scope.cards.push(angular.extend({}, newCard));
        };

        var postRecordLikes = function (product_id) {
            cardsApi.postRecordLikes(product_id)
                .then(function successCallback(product_id) {
                    // this callback will be called asynchronously
                    // when the response is available
                }, function errorCallback(response) {
                    // called asynchronously if an error occurs
                    // or server returns response with an error status.
                });
        };

    }

My routing.js (trying to configure it to direct to any URL containing integers/numbers). This always redirects back to login...: c .config(['$stateProvider', '$urlRouterProvider', function($stateProvider, $urlRouterProvider) {

        $urlRouterProvider.otherwise("/login");

        $stateProvider

            .state('login', {
                url: '/login',
                views: {
                    'menuContent': {
                        templateUrl: 'app/core/login/login.html'
                    }
                },
                controller: function ($ionicHistory, $scope) {
                    console.log('Clearing history!');
                    $ionicHistory.nextViewOptions({
                        historyRoot: true,
                        disableBack: true
                    });
                }


            })

            .state('product', {
                url: '/product',
                when:('/product/?:product_id'),
                views: {
                    'menuContent': {
                        templateUrl: 'app/components/product/product.html'
                    }
                }

Answer 1

a query string adds data to the end of a url, after a question mark. you then navigate to that url:

var myvar=234;
location="http://www.example.com/?"+myvar;

and in the second page get the variable by accessing the query string and stripping away the question mark:

var newvar=location.search.replace("?", ""); // 234

you would then use the 234 to make the specific ajax call, get the JSON, etc, etc
