Question

我正在为带有自定义标记的网站制作谷歌地图。制作标记，但是当点击标记时，我需要为每个标记打开信息框。我在互联网上搜索并尝试了很多东西，但它不会工作。

以下是代码：

有人有任何建议如何使信息框工作吗？

Answer 1

您需要为每个标记设置info属性，如此

marker.info = new google.maps.InfoWindow({
  content: 'Add some info here'
});

google.maps.event.addListener(marker, 'click', function() {
  marker.info.open(map, marker);
}

你可以而且应该为所有标记重新使用一个InfoWindow，但这非常简单。

运行下面的代码段进行测试：）

看看这个简单的解决方案。我试过这个，它工作正常。相应地修改你的代码。

 for (i = 0; i < latitude_longitude_array.length; i++) {      
        var data = latitude_longitude_array[i];
        var myLatlng = new google.maps.LatLng(data.latitude, data.longitude);

        var marker = new google.maps.Marker({
                position: myLatlng,
                map: map,
        });

        var geocoder = new google.maps.Geocoder();
            (function (marker, data) {
                geocoder.geocode(
                                {
                                    'latLng': myLatlng
                                },
                                function (results, status) {

                                    if (status == google.maps.GeocoderStatus.OK) {
                                        if (results[1]) {
                                            var infoWindow = new google.maps.InfoWindow();      

                                            infoWindow.setContent("Address" + ": " + results[1].formatted_address + " ");    

                                            google.maps.event.addListener(marker, "click", function (e) {
                                                infoWindow.open(map, marker);
                                            });
                                        }
                                        else {
                                            alert("No results found");
                                        }
                                    }
                                    else {
                                        alert("Geocoder failed due to: " + status);
                                    }
                                });
            })(marker, data);
    } //end of for
