在Angular JS中获取以前的URL而不是当前URL

Question

链接1 链接2

我正在尝试获取警报中的当前URL，但是我猜想角度脚本在警报之前首先运行，因此，当我单击链接2时，其显示链接1，反之亦然。在angularjs 1.7中加载页面后，我是否缺少任何内容或要获取页面的URL？

(function () {

    var app = angular.module('myApp');

    app.controller('initiativesController', ['$scope',
      function ($scope) {
          $scope.TestInitiatives = "Test";

          var url = window.location.pathname.split('/')[1];;
          alert(url)

          console.log($scope.TestInitiatives);
      }
    ]);
})();

Angular app.js

(function () {

    var myapp = angular.module('myApp', ["ui.router"]);

    myapp.config(function ($stateProvider, $locationProvider, $urlRouterProvider) {

        // For any unmatched url, send to /route1
        $urlRouterProvider.otherwise("/route1")

        $stateProvider
          .state('route1', {
              url: "/route1",
              templateUrl: "SOC/Views/route1.html",
              controller: "route1ctrl"
          })
          .state('route2', {
              url: "/route2",
              templateUrl: "SOC/Views/route2.html",
              controller: "route2ctrl"
          })

        $locationProvider.html5Mode({
            enabled: true,
            requireBase: false
        });

    });


})();
