谷歌地图信息窗口内的angularjs ng-click不会触发

Question

如何在 infowindow 中触发事件。我在谷歌地图信息窗口中有一个使用 ng-click 的按钮。当我单击它时，没有任何警报和错误。有什么想法吗？

var infoWindow = new google.maps.InfoWindow({
    maxWidth: 240,
    content: "<button ng-click=\"test()\">Click me</button>"
});

测试功能。

$scope.test = function() {
   alert('This is infowindow');
}

要触发 ng-click 事件，需要使用 $compile 服务编译信息窗口内容。

示例

angular.module('map-example', [])
    .controller('MapController', function($scope, $rootScope, $compile) {


        function initialize() {

            $scope.map = new google.maps.Map(document.getElementById('map'), {
                zoom: 4,
                center: { lat: -38.363, lng: 131.044 }
            });



            $scope.cities = [
                { title: 'Sydney', lat: -33.873033, lng: 151.231397 },
                { title: 'Melbourne', lat: -37.812228, lng: 144.968355 }
            ];


            $scope.infowindow = new google.maps.InfoWindow({
                content: ''
            });


            for (var i = 0; i < $scope.cities.length; i++) {


                var marker = new google.maps.Marker({
                    position: new google.maps.LatLng($scope.cities[i].lat, $scope.cities[i].lng),
                    map: $scope.map,
                    title: $scope.cities[i].title
                });

                var content = '<a ng-click="cityDetail(' + i + ')" class="btn btn-default">View details</a>';
                var compiledContent = $compile(content)($scope)

                google.maps.event.addListener(marker, 'click', (function(marker, content, scope) {
                    return function() {
                        scope.infowindow.setContent(content);
                        scope.infowindow.open(scope.map, marker);
                    };
                })(marker, compiledContent[0], $scope));

            }

        }

        $scope.cityDetail = function(index) {
            alert(JSON.stringify($scope.cities[index]));
        }

        google.maps.event.addDomListener(window, 'load', initialize);

    });

 html, body {
        height: 400px;
        margin: 0;
        padding: 0;
      }
      #map {
        height: 400px;
      }
