How to transfer my data to another page from ul menu menu in angular js

Question

I have a navigation menu with a submenu. My menu has the name of my product group, and it gets data from the JSON code that it selects from my SQL database.

I want to store the "product group identifier" in a variable in order to send it to another page that selects from the product table ProductGroup.productGroupId == Product.ProductGroupId.

I want to display my product name in a submenu. This is my HTML code:

<ul class="sub-menu">
    <div ng-app="firstApp" ng-controller="FirstController">
        <li ng-repeat="x in result">
            <a class="haschild" title="" href="">{{ x.GroupName }}</a>
            <ul>
                <div ng-controller="ProductController">
                    <li ng-repeat="x in names">
                        <a title="" href="">{{ x.name }}</a>
                    </li>
                </div>
            </ul>
        </li>
    </div>
</ul>

My angular app

<script>
    var rootApp = angular.module('rootApp', ['firstApp', 'secondApp', 'ProductApp']);
    var firstApp = angular.module('firstApp', []);
    firstApp.controller('FirstController', function($scope, $http) {
      $http.get("select2.php")
    .then(function (response) {$scope.result = response.data.records;});
    });

    var secondApp = angular.module('secondApp', []);
    secondApp.controller('SecondController', function($scope, $http) {
      $http.get("selectSource.php")
    .then(function (response) {$scope.result2 = response.data.records;});
    });
    var ProductApp = angular.module('ProductApp', []);
    ProductApp.controller('ProductController', function($scope, $http) {
      $http.get("selectProduct.php")
    .then(function (response) {$scope.names = response.data.records;});
    });

  </script>

You can use $ sessionStorage

For instance:

$sessionStorage.projectId = Product.ProductGroupId;

Each page will be associated with a controller. You can insert $ sessionStorage into the appropriate controller and get the resulting value.
