Angularjs 方向改变不'；我不能在有角度的地方工作

我试图检查角度方向改变的工作，但它不起作用

var myApp = angular.module('myApp',['ngTouch','matchmedia-ng']);

function checkOrientation($scope){
    if($scope.landscape){
        $scope.isLandscape="landscape";
        alert($scope.isLandscape);
    }
    else{
        $scope.isLandscape="portrait";
        alert($scope.isLandscape);
    }
}

myApp.controller('MainController', ['$scope', '$window','matchmedia',
    function($scope, $window, matchmedia) {
    $scope.submit = function() {
        alert("submitted!");
    }
    $scope.desktop = matchmedia.isDesktop();
    $scope.tablet =matchmedia.isTablet();
    $scope.phone = matchmedia.isPhone();
    $scope.landscape = matchmedia.isLandscape();

        if($scope.desktop){
            alert("desktop");
        }
        else if($scope.tablet){
            alert("tablet");
        }
        else if($scope.phone){
            $scope.isDevice = 'phone';
        }

        checkOrientation($scope);

        /*screen.bind('orientationchange', function () {
            $route.reload();
        });*/
        angular.element($window).bind('orientationchange', function ($scope) {
            checkOrientation($scope);
        });
}]);

我还尝试了$route.reload（）选项，但它也不起作用。它可以工作，但当我改变方向时就不行了

在checkOrientation中，您只需查看以下值即可查看您所处的方向：

$window.screen.orientation.type
