angularjs - 模态内的 NgMap(谷歌地图) - 不显示第二次

Question

我正在使用 NgMap 在我的 Angular 应用程序的模态内生成 map 。模式是使用 Controller 中的 $modal 注入(inject)器生成的，并使用模板 View 构建 html 代码。

模态框第一次出现时效果很好。虽然，第二次 map 完全乱了。 它显示了 map 的一些部分，其余部分覆盖着浅灰色。

这是初始化模态的内容

$modal.open({
    templateUrl: 'views/partials/modals/storeShowModal.html',
    controller: 'ModalShowStore',
    resolve: {
        store: function() {
            return store;
        }
    }
}); 

这是模态 Controller

appControllers.controller('ModalShowStore', ['$scope', '$modalInstance', 'store', 'NgMap', function ($scope, $modalInstance, store, NgMap) {

    $scope.center = store.latitude+","+store.longitude;
    $scope.position = store.latitude+","+store.longitude;

    NgMap.getMap().then(function(map) {});

    $scope.store = store;

    $scope.cancel = function () {
        $modalInstance.close();
    };

}]);

这是模板html

<div class="modal-header">
    <button type="button" class="close" data-dismiss="modal" data-ng-click="cancel()" aria-hidden="true">&times;</button>
    <h4 class="modal-title text-align-center fw-bold mt" id="myModalLabel18">{{ store.name }}</h4>
</div>
<div class="modal-body bg-gray-lighter">
    <div class="row">
        <div class="col-md-12">
            <ng-map center="{{ center }}" zoom="15">
                <marker position="{{ position }}"></marker>
            </ng-map>
        </div>
    </div>
</div>

任何想法，任何想法都非常欢迎。我想这与 html 的动态加载有关。 谢谢。

更新

当不使用模式而只是使用 div 时，问题仍然存在。当我隐藏 div 并再次显示它时， map 全部变灰。有趣的是，当我打开 Chrome 的控制台时， map 出现了。

Answer 1

尝试在 map 初始化后显式调用 resize 事件:

NgMap.getMap().then(function (map) {
     google.maps.event.trigger(map, "resize"); 
});

例子

angular.module('app', ['ngMap', 'ui.bootstrap'])

    .controller('myCtrl', function ($scope, $uibModal) {
       


        $scope.showModal = function () {
            $scope.modal = $uibModal.open({
                templateUrl: 'storeShowModal.html',
                controller: 'ModalShowStore',
                resolve: {
                    store: function () {
                        return { "latitude": 51.5285578, "longitude": -0.242023 };
                    }
                }
            });
        };

        $scope.closeModal = function () {
            $scope.modal.close();
        };
    })

    .controller('ModalShowStore', function ($scope,$uibModalInstance, NgMap, store) {
        
        
        $scope.center = [store.latitude,store.longitude];
        $scope.position = [store.latitude,store.longitude];
        

       
        NgMap.getMap().then(function (map) {
             google.maps.event.trigger(map, "resize"); 
        });
        
        $scope.store = store;

        $scope.cancel = function () {
            $uibModalInstance.close();
        };
    });
