Question

在这里，当我点击storeAreaInCookie，这将导致城市的纬度和长度，这些结果我必须存储在cookie中，需要使用我想在我的网站中使用的地方。但是当我试图使用这个代码时不存储cookie，并在控制台中说没有定义cookie存储。我可以解决这个问题吗？

 <div ng-app="MyApp" ng-controller="MyCtrl">
    <div ng-repeat="x in names">
     <div ng-click="storeAreaInCookie(x.city)" >{{x.city}}</div>
    </div>
    </div>
    <script>
    angular.module('MyApp', ['ngCookies'])
    .controller('MyCtrl', ['$scope', '$http',"$rootScope", "$cookieStore", function($scope, $http, $rootScope, $cookieStore) {
    $scope.storeAreaInCookie = function (area) {
            var geocoder =  new google.maps.Geocoder();
            var lat="";
            var long="";
            geocoder.geocode( { 'address': area}, function(results, status) {
                 if (status == google.maps.GeocoderStatus.OK) {
                        $rootScope.lat=results[0].geometry.location.lat();
                        $rootScope.long=results[0].geometry.location.lng();
                    } else {
                       alert("Something went wrong " + status);
                     }
                codeLatLng($rootScope.lat,$rootScope.long);
                 $(document).ready(function(){
                    $("#locationView").slideToggle();
                });
             });
          $cookieStore.put('lat',$rootScope.lat);
          $cookieStore.put('long',$rootScope.long);   
          alert("lat"+$cookieStore.get('lat'));
          alert("long"+$cookieStore.get('long'));
          };
    }]);
    </script>

Answer 1

确保添加参考文件

angular-cookies.js

它可能是依赖性错误

Answer 2

可能是你正在搞乱角度cookie依赖。在更改$ rootScope中的值后，您需要使用$rootScope.$apply()

手动运行摘要周期

<强> CODE

angular.module('MyApp', ['ngCookies'])
    .controller('MyCtrl', ['$scope', '$http', "$rootScope", "$cookieStore", "$q", function ($scope, $http, $rootScope, $cookieStore, $q) {
    $scope.names = [{
        "id": 1,
        city: "abc",
        lat: 123,
        long: 345
    }, {
        "id": 2,
        city: "asd",
        lat: 123,
        long: 345
    }, {
        "id": 3,
        city: "dfg",
        lat: 123,
        long: 345
    }];
    //mock ajax
    $scope.storeAreaInCookie = function (area) {
        var geocoder = new google.maps.Geocoder();
        var lat = "";
        var long = "";
        geocoder.geocode({
            'address': area.city
        }, function (results, status) {
            if (status == google.maps.GeocoderStatus.OK) {
                $rootScope.lat = results[0].geometry.location.lat();
                $rootScope.long = results[0].geometry.location.lng();
                $rootScope.$apply()
                $cookieStore.put('lat', $rootScope.lat);
                $cookieStore.put('long', $rootScope.long);
                alert("lat" + $cookieStore.get('lat'));
                alert("long" + $cookieStore.get('long'));
            } else {
                alert("Something went wrong " + status);
            }
            //codeLatLng($rootScope.lat, $rootScope.long);
            $(document).ready(function () {
                $("#locationView").slideToggle();
            });
        });

    };
}]);
