$ rootScope：infdig 10 $ digest（）迭代达成。使用event.preventDefault（）时中止

Question

我在角应用中检查身份验证，下面给出了代码 当我在代码中取消注释event.preventDefault（）时，它会给出[$ rootScope：infdig] 10 $ digest（）迭代。中止错误代码中的问题是什么建议

    var app = angular.module('sss', ['ui.router', 'ui.bootstrap', 'ngResource', "ngStorage", "ngProgress", "ngCookies", 'angular-jwt', 'ngLodash','tagged.directives.infiniteScroll']);
app.config(['$stateProvider', '$urlRouterProvider', '$locationProvider', "$httpProvider", function ($stateProvider, $urlRouterProvider, $locationProvider, $httpProvider) {
    $locationProvider.html5Mode(true);
    $urlRouterProvider.otherwise(function ($stateParams) {
        console.log("val check", $stateParams, window.location);
        window.location.href = "/undefined";

    });
    $stateProvider.state("jobs", {
        url: "/jobs",
        templateUrl: "views/dashboard.html",
        controller: "JobController as JobCtrl",
        resolve : {
            formInfo : ["AuthService",function (AuthService) {
                return AuthService.getFormInfo();
            }]
        }
    }).state("undefined", {
        url: "/undefined",
        templateUrl: "views/pagenotfound.html",
        bodyClass: "errors errors-404 errors-centered"
    }).state("login", {
        url: "/login",
        templateUrl: "views/login.html",
        controller: "LoginController as LoginCtrl",
        resolve : {
            formInfo : ["AuthService",function (AuthService) {
                return AuthService.getFormInfo();
            }]
        }
    }).state("home",{
        url:"/home",
        resolve : {
          redirect:function($window)
          {
               $window.location.href = "/jobs"
          }
        }
    })
}]);

   

app.run(['$rootScope','$urlRouter', 'ngProgressFactory', '$state', '$compile', '$location', '$cookies', 'jwtHelper','AuthService', function ($rootScope,$urlRouter ,ngProgressFactory, $compile, $state, $location, $cookies, jwtHelper,AuthService) {
    $rootScope.$on('$stateChangeStart', function (event, toState, toParams, fromState, fromParams, options) {
        $rootScope.progressbar = ngProgressFactory.createInstance();
        $rootScope.progressbar.start();
        $rootScope.location = $location;
    });

  var authPreventer =  $rootScope.$on('$locationChangeStart', function (event, toState, toParams, fromState, fromParams, options) {

        var notCheckRoute = ["/undefined", "/signin", "/login"];
          //event.preventDefault();
          AuthService.checkPermission()
            .then(function(data) {

              console.log('if',$location.path(),data.active);

                if(data.active){

                    $location.path('/jobs'); 
                }else{
                    $urlRouter.sync();
                    $location.path('/login');
                }
            });
    });

    $rootScope.$on('$stateChangeSuccess', function (event, toState, toParams, fromState, fromParams) {
        $rootScope.progressbar.complete();
        $rootScope.bodyClass = toState.bodyClass;
    });

    $rootScope.$on('$stateChangeError', function (event) {
        //$state.go('undefined');
    });
}]);
